Testosterone Boosters Ranked by Evidence (2026)
How far up the ladder do I need to go to fix low testosterone?
Shilajit at 7.4, phosphatidylserine at 7.3, tongkat ali at 7.0. TRT ranks seventh at 5.7 and wins nine of the eleven use cases outright. That inversion is the whole page: replacement works better than any herb, and costs you the production you were trying to protect.
- TRT holds the top score on hormonal (9.0), libido (8.0), muscle growth (7.5), strength (7.5), body composition (7.0), bone (7.0), energy (7.0), mood (6.5) and metabolic health (6.0). It still ranks seventh of eight.
- It ranks seventh because the score charges for what the herbs do not cost you: your own production shuts down, fertility usually goes with it, and stopping means going back to a baseline that is now lower than where you started.
- Shilajit is first at 7.4 and is the only member that beats TRT on anything physiological, taking male fertility at 7.5 against TRT's 2.0.
- Ashwagandha wins stress resilience at 7.5, which is the row that matters if cortisol is what is suppressing your axis in the first place.
- Phosphatidylserine ranks second at 7.3 and wins nothing here. Read the methodology note before you buy it for testosterone.
- The ranking is the live score. When a member's score moves, this page moves with it.
The Ranking
8 interventions ranked by live BioHarmony score.
Rank 1: Shilajit
7.4 / 10 🛡 Strong RecommendFulvic and humic acid mineral resin. Retail supplement. BioHarmony 7.4, strong recommend.
Rank 2: Phosphatidylserine
7.3 / 10 🛡 Strong RecommendSecond on the composite and the row most likely to mislead you. Its 7.3 is a whole-report score built on cognition and memory in older adults, where the 1991 Crook trial at 300 mg a day is still the anchor, plus cortisol-axis work including Starks 2008 at 600 mg a day for exercise-induced cortisol. Inside this category it wins nothing: libido 2.0, male fertility 1.5, hormonal 5.5. Pick it when high cortisol load is what is flattening you and you want the phospholipid rather than the adaptogen, and only then. If you came here for testosterone, this row is not your answer, and the methodology note explains exactly why it ranks this high.
Phospholipid, cortisol-axis support. Retail supplement. BioHarmony 7.3, strong recommend.
Rank 3: Tongkat Ali
7.0 / 10 🛡 Strong RecommendThird, and the most direct testosterone play among the supplements. Tambi 2012 normalised testosterone into the reference range in 90.8% of hypogonadal men after 200 mg a day for one month, and the distinctive mechanism is reducing sex-hormone-binding globulin, which raises free testosterone and is notoriously hard to shift. It takes second place on libido (6.3), muscle growth (5.5) and body composition (5.2), behind TRT in each. Pick it over shilajit when free testosterone and libido are the target rather than fertility. Use a standardised extract that matches the trials, because cheap bulk powder carries both active-marker and heavy-metal uncertainty.
Eurycoma longifolia root extract, SHBG and cortisol effects. Retail supplement. BioHarmony 7.0, strong recommend.
Rank 4: Ashwagandha
6.8 / 10 Worth tryingFourth, and the winner of the one row no hormone on this page can take: stress resilience at 7.5. Arumugam 2024 pooled nine randomised trials in 558 participants and found reduced perceived stress, anxiety and serum cortisol against placebo, and Fatima 2024 found lower HAM-A anxiety scores across five RCTs. Pick it first if chronic stress is what is suppressing your axis, because lowering cortisol addresses the cause rather than the readout. It carries the most specific safety list in the category: documented liver-injury reports, thyroid stimulation, and pregnancy avoidance. Extracts differ enormously, and some sedate where others energise.
Adaptogenic herb, cortisol reduction. Retail supplement. BioHarmony 6.8, worth trying.
Rank 5: Kisspeptin-10
6.4 / 10 Worth tryingFifth, and the most elegant mechanism here attached to the thinnest file for the form people actually buy. Kisspeptin is the master upstream switch of the reproductive axis, and Abbara 2015 showed a single subcutaneous kisspeptin-54 dose triggered egg maturation in 95% of women at high risk of ovarian hyperstimulation. The problem is that the strong data used kisspeptin-54, the kisspeptin-10 studies used infusion, and kisspeptin-10's half-life is minutes, which makes a home subcutaneous shot poorly aligned with the evidence. Pick it only inside a supervised fertility setting or a documented central hypogonadism workup.
Investigational neuropeptide, upstream HPG trigger. Gray market. BioHarmony 6.4, worth trying.
Rank 6: Gonadorelin (GnRH)
6.3 / 10 Worth tryingSixth, and the only member here that was once an approved drug and is now mostly bought for a use it was never tested for. It is synthetic GnRH, the decapeptide that tells the pituitary to release LH and FSH, and Belchetz 1978 established that the pulse pattern is what makes it work. The demand driver, keeping the testes running during testosterone therapy, is extrapolated from hCG data in Hsieh 2013 rather than proven directly. Pick it as a deliberate adjunct alongside TRT, with the pulsatile schedule its minutes-long half-life demands, not as a set-and-forget shot.
Synthetic GnRH, formerly FDA approved. Compounded prescription. BioHarmony 6.3, worth trying.
Rank 7: TRT (Testosterone Replacement Therapy)
5.7 / 10 🤷 NeutralSeventh of eight, and the winner of nine of the eleven use-case rows. Nothing else on this page comes close on effect: hormonal 9.0, libido 8.0, muscle growth 7.5, strength 7.5. Bhasin 1996 established the muscle-size and strength effect, the T Trials support sexual function and mood, and TRAVERSE lowered the cardiovascular concern. It ranks here because the score charges for dependency and reversibility, and those charges are real: your own production downregulates, fertility usually goes with it, and the ordinary case is lifelong. Pick it when two early-morning tests document symptomatic hypogonadism and the lifestyle work is already done, not before.
Testosterone replacement therapy. Prescription, lifelong. BioHarmony 5.7, neutral.
Rank 7: Pine Pollen
5.7 / 10 🤷 NeutralTied at the bottom, and included precisely because it is the most marketed testosterone claim in this category with the least behind it. Saden-Krehula 1971 found trace androgens in pine pollen, and that single chemistry finding carries almost the entire hormonal story. No PubMed-indexed human trial shows it raises testosterone, and its hormonal subrating of 3.5 is the lowest on the page. The real evidence is animal antioxidant and liver-protective data plus centuries of use as a tonic food. Pick it as a cheap nutrient-dense whole food. If testosterone is the goal, pick something else.
Whole-food tonic with trace androgens. Retail supplement. BioHarmony 5.7, neutral.
Best Pick by Use Case
| Use Case | Winner | Runner-Up | Why |
|---|---|---|---|
| Hormonal | TRT (Testosterone Replacement Therapy) 9.0 | Shilajit 7.5 | The widest gap on this page, and it should be. Giving someone testosterone raises their testosterone; that is not a claim requiring interpretation. Shilajit's 7.5 is the best any supplement manages. Pine pollen sits last at 3.5, which is the honest score for a hormonal claim resting on trace androgen content and no human trial. |
| Libido | TRT (Testosterone Replacement Therapy) 8.0 | Tongkat Ali 6.3 | Tongkat ali's 6.3 is the best non-prescription answer, on stress-linked libido rather than raw androgen. Note phosphatidylserine at 2.0, second in the overall ranking and second to last in this row. If low desire is the symptom, the overall ordering on this page will point you at the wrong product. |
| Fertility Male | Shilajit 7.5 | Ashwagandha 6.0 | The one row where the top of the ranking beats testosterone outright, and the most important row on the page. TRT scores 2.0 here because exogenous testosterone suppresses spermatogenesis. If you want children in the next few years, this row outranks every other row, and shilajit's sperm parameter data in Biswas 2010 is why it sits first. |
| Muscle Growth | TRT (Testosterone Replacement Therapy) 7.5 | Tongkat Ali 5.5 | A two-point gap, and Bhasin 1996 is the reason: supraphysiologic testosterone increased muscle size and strength even without exercise. No herb in this category has produced anything comparable. Pine pollen is not scored for this use case. |
| Body Composition | TRT (Testosterone Replacement Therapy) 7.0 | Tongkat Ali 5.2 | Same shape as the muscle row and the same explanation. What the numbers do not show is that the body-composition benefit lasts exactly as long as the therapy does, which is the trade the ranking is charging for. Pine pollen is not scored here. |
| Strength Power | TRT (Testosterone Replacement Therapy) 7.5 | Shilajit 6.0 | Shilajit's 6.0 is a genuine second place rather than a courtesy one, on preserved fatigue-related strength at the higher dose in Keller 2019. Only six of the eight members are scored for this use case: kisspeptin-10 and pine pollen have no strength data at all. |
| Bone Joint | TRT (Testosterone Replacement Therapy) 7.0 | Shilajit 6.5 | The closest of TRT's nine wins, half a point. Bone density is one of the documented reasons to treat hypogonadism rather than a cosmetic one, and shilajit's collagen-turnover and bone-marker data puts it unusually close here. Phosphatidylserine's 1.5 is the floor. |
| Energy | TRT (Testosterone Replacement Therapy) 7.0 | Shilajit 6.5 | Another half-point row, and the one most people are actually describing when they say they think their testosterone is low. Worth noting that fatigue has many more common causes than hypogonadism, and both winners here score below what fixing sleep would. |
| Mood | TRT (Testosterone Replacement Therapy) 6.5 | Tongkat Ali 6.0 | Half a point between a prescription hormone and a root extract, which is the narrowest justification for replacement anywhere on this page. Ashwagandha's 6.0 ties tongkat ali. If mood is the presenting complaint rather than a hormone panel, the ordering here argues for starting at the supplement end. |
| Stress Resilience | Ashwagandha 7.5 | Phosphatidylserine 6.5 | The only row no hormone wins, and TRT scores 4.0 in it. This matters more than its position suggests: chronically elevated cortisol suppresses the HPG axis, so for a meaningful number of men this row is the cause and the hormonal row is the symptom. Gonadorelin is not scored here. |
| Metabolic Health | TRT (Testosterone Replacement Therapy) 6.0 | Ashwagandha 4.0 | A two-point win on the lowest-scoring row in the table, which is the right way to read it: nothing in this category is a metabolic intervention. TRT's 6.0 reflects the evidence in hypogonadal men with type 2 diabetes or metabolic syndrome, not a general effect in men with normal levels. |

Cost Comparison
| Intervention | Monthly Cost | Notes |
|---|---|---|
| Ashwagandha | $15 to $30 | Retail supplement, priced 2026-09-07 at 600 mg a day of a standardised third-party-tested extract. The cheapest line on the table and the winner of the stress row. Generic root powder runs $5 to $15 and carries real adulteration risk, so the premium here buys testing rather than potency. |
| Tongkat Ali | $20 to $40 | Retail supplement, priced 2026-09-07 at 200 mg a day of a verified standardised extract, which is the dose Tambi 2012 used. Cheap bulk powder is far less and does not match the trial material on active markers or heavy-metal testing. |
| Pine Pollen | $20 to $45 | Retail, priced 2026-09-08 at 5 to 10 g of powder a day. Reasonable value as a nutrient-dense tonic food, which is what the evidence supports. Poor value per unit of testosterone, because no human trial shows it moves testosterone at all. |
| Phosphatidylserine | $20 to $50 | Retail supplement, priced 2026-09-08 at 300 mg a day, the dose behind the older memory trials. The exercise-cortisol work in Starks 2008 used 600 mg a day, so the cortisol use case costs roughly double what this line shows. |
| Shilajit | $25 to $50 | Retail supplement, priced 2026-09-08 at 300 to 500 mg a day of purified capsules, which matches the trial dose. Resin runs $50 to $100 per jar lasting four to eight weeks. Do not buy on price here: heavy-metal contamination is the real risk and only lot-specific testing rules it out. |
| Kisspeptin-10 | $25 to $65 | ESTIMATE, priced 2026-09-08, research-chemical channel, at 100 to 200 mcg per subcutaneous shot plus roughly $15 a month for bacteriostatic water and syringes. Cheaper than most of the supplements above it, which tells you nothing good: there is no approved product and no product standard behind the label. |
| Gonadorelin | $50 to $150 | ESTIMATE, priced 2026-09-08, compounding-pharmacy channel, at 100 to 300 mcg several times weekly to daily. This sits on top of the testosterone protocol it accompanies rather than replacing any of it, so the real monthly figure for its main use is this line plus the TRT line. |
| TRT | $50 to $300 | Priced 2026-09-08. Generic injectable testosterone with insurance and documented hypogonadism runs under $50 a month; cash-pay telehealth clinics bundling medication, labs and visits run $150 to $300. Monitoring is not an optional add-on, and the cost is indefinite rather than a course you finish. |
| The difference | $15 to $300, and price is the wrong axis here | Six of the eight have a real published price, which is unusually good coverage for a BioHarmony ranking. Only kisspeptin-10 and gonadorelin are estimated, and gonadorelin's estimate is a compounding-pharmacy price rather than a vial guess.The spread is narrow enough that cost should not decide this. A month of the highest-scoring supplement and a month of cash-pay TRT differ by about $250, and the actual difference between them is that one is reversible and one is a commitment. Note also that the cheapest line on the page belongs to the row that wins stress resilience, and the cheapest peptide belongs to the member with the thinnest data for the form sold. Every figure carries a pricing date. |
Who Should Pick What?
You feel flat and have never had your testosterone measured
Tie
None of the eight, yet. Get two early-morning tests before you buy anything on this page, because the symptoms that send men here, fatigue, low mood, low drive, have many more common causes than hypogonadism. Every member of this category is a different answer depending on what the number says, and four of them are the wrong answer if the number is normal.
Documented low testosterone on two morning tests, lifestyle already handled
TRT (Testosterone Replacement Therapy)
This is the population every guideline on this page was written for, and the nine use-case wins are real. Go in knowing the terms: your own production shuts down, fertility usually goes with it, monitoring is not optional, and the ordinary case is lifelong. Nick's own recorded position is to exhaust the natural optimisation route first, because people regularly double or triple their levels doing that.
You want children in the next few years
Shilajit
The fertility row inverts the whole page. Shilajit scores 7.5 on male fertility against TRT's 2.0, on improved sperm parameters in oligospermic men in Biswas 2010. If replacement is indicated anyway, that is a urology conversation about preserving fertility alongside it, and gonadorelin exists for exactly that job.
Chronic stress is what is flattening you
Ashwagandha
It wins stress resilience at 7.5, the only row no hormone takes, and cortisol suppression of the HPG axis is a real mechanism rather than a wellness story. Cycle it rather than running it continuously, check it against your thyroid status first, and know that extracts differ enormously, with some sedating and some energising.
Low-normal testosterone with high SHBG
Tongkat Ali
This is the specific case tongkat ali is built for. Reducing sex-hormone-binding globulin raises free testosterone, and SHBG is notoriously hard to move, which is why Nick describes it as the interesting part of the mechanism. Use a standardised extract at 200 mg a day in the morning and retest labs at four to twelve weeks rather than guessing.
Already on TRT and want to keep your testes working
Gonadorelin (GnRH)
It is the on-label-shaped answer to an off-label question. Understand that the fertility-preservation use is extrapolated from hCG data rather than proven directly for gonadorelin, and that the dosing is fragile: minutes-long half-life, pulses required, most supply compounded. hCG is the better-tested tool for the same goal.
You bought pine pollen because it raises testosterone
Tie
It does not, on any human evidence. The claim rests on trace androgen content found in 1971 and animal work, and its hormonal subrating of 3.5 is the lowest here. Keep it if you want a cheap nutrient-dense tonic food with a clean safety record and a pine allergy check. Replace it with tongkat ali or shilajit if the hormone was the point.
You want the upstream switch rather than the hormone
Kisspeptin-10
Mechanistically it is the right answer and practically it usually is not. The strongest trial data used kisspeptin-54, the kisspeptin-10 work used infusion, and the half-life is minutes, so a home subcutaneous shot is not the evidence you think you are buying. In a supervised fertility setting it is worth knowing about. Outside one, it is a gray-market vial.
How This Ranking Is Built
- Ranked by
- the live BioHarmony overall score
- What is included
- Every published BioHarmony intervention report whose primary claimed benefit is raising, restoring or protecting male androgen status and the vitality that tracks it: testosterone itself, the hypothalamic-pituitary-gonadal axis upstream of it, sex-hormone-binding globulin, sperm parameters, and the cortisol load that suppresses the axis. Interventions that improve sexual function through another pathway are out, which is why PT-141 and melanotan II are excluded despite sharing the search cluster. Growth-hormone secretagogues are a different axis and have their own ranking. Adding a new report inside this boundary adds a row.
- Kept current
- Positions and scores are read live from each intervention report on every page load, so the order re-renders the moment any member is rescored. Membership is rebuilt nightly against the inclusion rule above.
The order on this page is the live BioHarmony overall score, read from each member's report when the page renders. It is not an editorial ranking, and nothing about it is fixed. When a member's score changes, the row moves that night.
Two members tie at 5.7. Within the tie the order is by upside total, the sum of the benefit dimensions before risk is subtracted: TRT 3.045, pine pollen 1.23. That is a wide gap for a tie, and it is the clearest signal on the page that these two arrive at the same score from opposite directions. TRT has large benefits and large costs. Pine pollen has small benefits and small costs. Treat the tie as an artefact of a single number, not as equivalence.
Why a prescription hormone ranks below a herb. This is the question the page exists to answer, so here it is directly. The BioHarmony overall combines effect size with evidence quality, safety, access, cost, reversibility and dependency. TRT wins on effect and evidence and loses badly on the last two. Starting exogenous testosterone downregulates your own production through the same feedback loop it is replacing, fertility usually goes with it, and the ordinary case is lifelong therapy where stopping returns you to a baseline lower than the one you started from. A herb you can stop on a Tuesday with no rebound is charged nothing for that. The nine use-case wins are what TRT does. The seventh-place ranking is what it costs. Both are true, and the page shows you both deliberately.
A caveat that cuts the other way. The ranking criterion is each member's overall report score, which is a whole-report judgement across all of its uses, not a score for this category. Phosphatidylserine is the clear case: it ranks second at 7.3 on the strength of cognition and memory evidence in older adults, and inside this category it scores 5.5 hormonal, 2.0 libido and 1.5 male fertility. It earns its place in the boundary through the cortisol-testosterone axis and nothing more. Read the use-case table, not the ordering, if you have a specific symptom.
The use-case table uses eleven rows drawn from the subratings the members share. Four members carry a full 66-use-case subrating set; kisspeptin-10 is scored across 15 use cases, gonadorelin across 12 and pine pollen across 21, so those three are absent from some rows. Where a member is not scored for a use case the note says so, rather than letting a blank read as a zero. The three mature supplements sweep the runner-up slots for the same reason the pilot's two approved drugs did: more of them has been measured.
This category spans four different access channels in eight rows, which no other BioHarmony ranking does. Five members are ordinary supplements, one is a gray-market research peptide, one is a compounded prescription with no marketed product, and one is a controlled substance requiring two confirmatory morning tests. The access row carries that span; the score already has it priced in.
Costs in the table are ESTIMATES with a pricing date where no retail product exists. Treat them as channel estimates, not quotes.
Research Highlights
-
Mechanism Difference
These eight act at four different points on one axis, and treating them as interchangeable testosterone boosters is the mistake this page is built to correct.At the top of the axis, kisspeptin-10 is the upstream trigger that tells the hypothalamus to release GnRH, and gonadorelin is synthetic GnRH itself, telling the pituitary to release LH and FSH. Both work by asking your body to make more. At the bottom, TRT skips the axis entirely and supplies the finished hormone, which is why it wins on effect and why feedback shuts the rest of the axis down.The supplements work sideways rather than up or down. Tongkat ali's distinctive action is reducing sex-hormone-binding globulin, which frees testosterone you already have rather than making more. Ashwagandha and phosphatidylserine lower cortisol, which removes a brake on the axis. Shilajit is a mineral and fulvic-acid matrix rather than a receptor-targeting molecule, which is why its evidence spans testosterone, sperm, bone and fatigue at once. Pine pollen contains trace androgens, which sounds like the most direct mechanism here and is the least supported.
-
Safety Comparison
There is no class-wide contraindication across these eight, because they are not a class. What repeats is hormone-sensitive cancer: shilajit, tongkat ali, kisspeptin-10 and gonadorelin all name it, and TRT excludes active prostate or breast cancer outright. Pregnancy appears on nearly every list, which matters on a male-vitality page mainly because these products end up in shared households, and TRT gels specifically carry a household-contact transfer warning.The compound-specific items are where the real decisions live. Ashwagandha carries the most active safety file: documented liver-injury reports, thyroid stimulation that conflicts with levothyroxine, and interactions with sedatives and immunosuppressants. Shilajit's exclusions include hemochromatosis and bleeding disorders alongside the heavy-metal sourcing rule. Tongkat ali names unexplained high PSA. TRT's list is the longest and the most clinical: untreated severe sleep apnea, baseline polycythemia, uncontrolled heart failure or hypertension, and fertility plans in the next twelve months without a urology plan. Pine pollen's only real one is a pine allergy.
-
Cost Comparison
This is the rare BioHarmony category where the price spread is narrow and six of eight members have a real published price rather than a research-vial estimate. A month of ashwagandha is $15 to $30. A month of cash-pay telehealth TRT is $150 to $300, and under $50 with insurance and a documented diagnosis.That is roughly a ten-to-one spread at the extremes and much less in the middle, which means cost is not the axis this decision turns on. The two estimated lines are kisspeptin-10 at $25 to $65 for research-chemical material, and gonadorelin at $50 to $150 through a compounding pharmacy. Note that gonadorelin's main use adds to a TRT bill rather than replacing it. The cost that does not appear in this table is TRT's monitoring, which is not optional, and its duration, which is usually the rest of your life.
-
Evidence Maturity
Every member of this category has been given to human beings, which separates it sharply from the more experimental BioHarmony rankings. What differs is how much and how well.TRT has the deepest file by a wide margin: TRAVERSE on cardiovascular safety, the T Trials on sexual function and mood, a 28-RCT pooled analysis on erectile function, and formal guidelines from both the Endocrine Society and the American Urological Association. Ashwagandha has multiple meta-analyses. Phosphatidylserine has trials going back to 1991 and a recent largely null result in healthy children, which is a useful reminder that its evidence is population-specific.The thinner files are thinner in a specific way. Shilajit's testosterone and fertility trials are small and funded by the branded ingredient supplier. Tongkat ali's headline 90.8% normalisation figure comes from a one-month study in hypogonadal men, and newer reviews still rate the broader booster category as uncertain. Kisspeptin-10's strongest data used a different molecule, kisspeptin-54. And pine pollen has no PubMed-indexed human trial for the claim it is sold on.
-
Editorial Verdict
The honest answer for most men who land on this page is that the question is wrong. You do not need to know which testosterone booster is best. You need a morning blood test, and then one of two very different conversations.If the number is normal, none of these eight is treating a problem you have. Ashwagandha for a genuine cortisol load and tongkat ali for high SHBG are the two defensible reasons to buy anything here, and both are specific rather than general.If the number is low and confirmed on two morning tests, TRT is what works, and the seventh-place ranking is not an argument against it. It is a full accounting of the trade: nine use-case wins on one side, and dependency, suppressed fertility and an indefinite commitment on the other. The supplements above it in the ranking are not better treatments for hypogonadism. They are cheaper, reversible, lower-ceiling options that score well because they cost you almost nothing when they do not work.
-
Ranking Stability
This ranking is not an opinion that gets refreshed quarterly. The order is the live BioHarmony overall score for each member, resolved when the page loads, so a rescoring of any one report reorders the page that night without an editorial pass.Expect this category to move less than the experimental ones. Six of the eight are mature interventions with settled evidence bases, and the gap between first and last is 1.7 points. The two that could move are kisspeptin-10, where a trial of kisspeptin-10 itself rather than kisspeptin-54 would resolve the central ambiguity, and gonadorelin, where a dedicated trial of the TRT-adjunct use would replace an extrapolation from hCG data with direct evidence. A larger independent shilajit trial, not funded by the ingredient supplier, would move the top of the page in either direction.
Frequently Asked Questions
- What is the best testosterone booster?
- Shilajit scores highest at 7.4, with tongkat ali at 7.0 the most direct testosterone play among the supplements. But the honest answer is that TRT wins nine of the eleven use cases on this page including hormonal at 9.0, and it ranks seventh. Nothing you can buy over the counter comes close to the effect of the hormone itself. What the supplements offer is a much smaller effect at almost no cost if it does not work.
- Why does TRT rank below shilajit if it works better?
- Because the score charges for what the intervention costs you, not just what it does. TRT wins on effect and evidence and loses on reversibility and dependency: your own production downregulates, fertility usually goes with it, and the ordinary case is lifelong therapy where stopping returns you to a baseline lower than where you started. A herb you can stop on a Tuesday with no rebound is charged nothing for that.
- Will any of these raise my testosterone if it is already normal?
- Probably not meaningfully, and none of these reports claims otherwise. Tongkat ali's headline 90.8% normalisation figure came from hypogonadal men, and shilajit's trials were small and supplier-funded. The two defensible reasons to take something here with a normal panel are a genuine cortisol load, where ashwagandha wins stress resilience at 7.5, and high sex-hormone-binding globulin, which is tongkat ali's specific mechanism.
- Does pine pollen raise testosterone?
- No human trial shows that it does. The claim rests on trace androgen content identified in 1971 plus animal work, and its hormonal subrating of 3.5 is the lowest of the eight. Its real evidence is animal antioxidant and liver-protective data plus a long history as a tonic food. It is a reasonable cheap nutrient source and a poor hormone lever.
- What if I want children?
- That single fact reorders this entire page. TRT scores 2.0 on male fertility because exogenous testosterone suppresses sperm production, while shilajit scores 7.5 on improved sperm parameters in oligospermic men. If replacement is indicated anyway, preserving fertility alongside it is a urology conversation, and gonadorelin and hCG exist for exactly that, with hCG the better-tested of the two.
- Should I try supplements before TRT?
- Get tested first, then decide. If the number is normal, the supplements are not treating a problem you have. If it is low and confirmed on two morning tests, the guidelines and the score both point at treatment, and Nick's own recorded position is to exhaust the natural optimisation route first, because people regularly double or triple their levels doing the fundamentals properly.
- Is gonadorelin the same as hCG?
- No. Gonadorelin is synthetic GnRH acting one level higher, telling the pituitary to release LH and FSH, while hCG acts directly on the testes as an LH analogue. They are used for the same goal during testosterone therapy, and the evidence gonadorelin's use rests on is hCG's, not its own. Gonadorelin's half-life is minutes and requires pulsed dosing, which makes it harder to run correctly.
- How often does this ranking change?
- Whenever any member's score changes. The order is the live BioHarmony overall pulled from each report at render time, and a rescoring reorders the page that night with no editorial pass. Expect this category to move less than the experimental ones, because six of the eight are mature interventions with settled evidence bases and the gap from first to last is 1.7 points.
Evidence Sources
- RCT Clinical evaluation of purified shilajit on testosterone levels in healthy volunteers (2016) Testosterone and DHEAS increases in healthy men after 500 mg a day for 90 days. The anchor for shilajit's 7.5 hormonal subrating, and funded by the branded ingredient supplier.
- RCT Clinical evaluation of spermatogenic activity of processed shilajit in oligospermia (2010) Improved sperm parameters in oligospermic men. The basis for shilajit's 7.5 male-fertility subrating, the only score on this page that beats testosterone itself.
- RCT Shilajit supplementation and connective-tissue and fatigue-related strength in overweight and obese adults (2019) Better preservation of fatigue-related strength at the higher dose. Supports shilajit's 6.0 strength-power subrating, second only to TRT.
- Regulatory FDA: lead, chromium and arsenic in some traditional Ayurvedic medicines (2026) Heavy-metal contamination in traditional Ayurvedic preparations. The reason unpurified shilajit without lot-specific testing is not an acceptable product regardless of price.
- RCT Standardised water-soluble extract of Eurycoma longifolia in late-onset hypogonadism (2012) Testosterone normalised into the reference range in 90.8% of hypogonadal men after 200 mg a day for one month. The single most quoted figure for tongkat ali, from a one-month study.
- RCT Eurycoma longifolia and stress hormones and mood in moderately stressed subjects (2013) Improved stress-hormone profile and mood state. Behind tongkat ali's 6.0 mood subrating, which ties ashwagandha and sits half a point under TRT.
- Systematic review Eurycoma longifolia and male reproductive and hormonal outcomes: a review (2022) The strongest single anchor on the tongkat ali report. Newer reviews still rate the broader testosterone-booster category as uncertain.
- Regulatory EFSA novel-food safety opinion on Eurycoma longifolia root extract (2021) European safety assessment of standardised tongkat ali extract. Part of the basis for its contraindication list.
- Meta-analysis Effects of ashwagandha on stress, anxiety and cortisol: systematic review and meta-analysis (2024) Nine randomised trials, 558 participants. Reduced perceived stress, anxiety and serum cortisol versus placebo. The anchor for the 7.5 stress-resilience subrating that wins the only row no hormone takes.
- Meta-analysis Ashwagandha and anxiety: HAM-A outcomes across five randomised trials (2024) Lower HAM-A anxiety scores across five RCTs. A second independent pooled result on the same axis.
- RCT A prospective, randomized double-blind, placebo-controlled study of the safety and efficacy of a high-concentration full-spectrum ashwagandha root extract in reducing stress and anxiety in adults (2012) The original cortisol-reduction RCT that started the modern ashwagandha literature.
- Systematic review Ashwagandha and physical performance: a systematic review (2021) Supports the 5.0 strength-power and 5.0 muscle-growth subratings. Real but modest, and well below TRT's 7.5 on both.
- Case series Ashwagandha-induced liver injury: case series (2020) Documented liver-injury reports. The reason current or past liver disease is a hard exclusion on the ashwagandha report rather than a soft caution.
- RCT Effects of phosphatidylserine in age-associated memory impairment (1991) The 300 mg/day AAMI trial that anchors phosphatidylserine's overall score. Cognition in older adults, which is why it ranks second here while winning nothing in this category.
- RCT The effects of phosphatidylserine on endocrine response to moderate intensity exercise (2008) 600 mg a day blunted the exercise-cortisol response. The only reason phosphatidylserine sits inside this category boundary at all.
- RCT Phosphatidylserine in mild cognitive impairment: a randomized trial (2025) 190 randomized MCI patients with positive cognitive findings, from a multi-ingredient formula, so PS-specific attribution is not separable.
- RCT Phosphatidylserine supplementation in healthy children: a randomized controlled trial (2025) 209 randomized healthy children. No total-cohort primary or secondary outcome differences. A useful reminder that phosphatidylserine's evidence is population-specific.
- RCT Efficacy of kisspeptin-54 to trigger oocyte maturation in women at high risk of ovarian hyperstimulation syndrome (2015) Egg maturation triggered in 95% of women at high OHSS risk. The strongest data in the kisspeptin file, and it used kisspeptin-54 rather than the kisspeptin-10 people buy.
- Observational The GPR54 gene as a regulator of puberty (2003) Established KISS1R as the upstream switch of the reproductive axis. The mechanism paper behind the entire kisspeptin field.
- RCT Kisspeptin-10 administration and LH release in healthy men (2011) Direct human proof of concept that kisspeptin-10 drives LH release, delivered by infusion rather than subcutaneous injection.
- RCT Kisspeptin and sexual and attraction brain processing: a randomized clinical trial (2023) Early signal on sexual desire in men, supporting kisspeptin-10's 4.8 libido subrating. Early, and again with the caveat about which kisspeptin was used.
- Animal study Hypophysial responses to continuous and intermittent delivery of hypothalamic gonadotropin-releasing hormone (1978) The foundational finding that GnRH must be pulsed, not continuous, or the pituitary desensitises. The reason gonadorelin's dosing schedule is fragile rather than convenient.
- Cohort study Concomitant intramuscular human chorionic gonadotropin preserves spermatogenesis in men undergoing testosterone replacement therapy (2013) hCG preserved spermatogenesis during TRT. This is the evidence gonadorelin's headline use is extrapolated from, not a gonadorelin trial.
- Cohort study Pulsatile gonadotropin-releasing hormone therapy for ovulation induction in hypothalamic amenorrhea (1990) True pulsatile pump delivery achieving physiological, low-hyperstimulation ovulation. The best-supported clinical use of gonadorelin, and not the one it is currently bought for.
- Systematic review Fertility induction in male hypogonadotropic hypogonadism (2024) Pulsatile GnRH for fertility induction in men with central hypogonadism, with the logistical demands that go with it.
- RCT Cardiovascular safety of testosterone-replacement therapy (TRAVERSE) (2023) Lowered concern about major adverse cardiovascular events, while leaving atrial fibrillation, pulmonary embolism and blood-pressure signals open. The largest safety trial behind TRT's score.
- RCT Effects of testosterone treatment in older men (The T Trials) (2016) Sexual-function and mood benefits in older men with low testosterone. Behind the 8.0 libido and 6.5 mood subratings that win both rows.
- RCT The effects of supraphysiologic doses of testosterone on muscle size and strength in normal men (1996) Increased muscle size and strength, with and without exercise. The evidence behind TRT's 7.5 muscle-growth and 7.5 strength-power subratings, both of which no herb comes within two points of.
- Meta-analysis Testosterone therapy and erectile function: pooled analysis of 28 RCTs (2024) 28 RCTs, 3,461 patients. Erectile-function scores improved without statistically significant intermediate-term prostate or urinary worsening.
- Meta-analysis Testosterone and depression: systematic review and meta-analysis (2009) A second independent signal on mood, supporting TRT's 6.5 mood subrating.
- Guideline Endocrine Society clinical practice guideline: testosterone therapy in men with hypogonadism (2018) The formal diagnostic standard: two separate early-morning confirmatory tests before treatment. The reason the first persona on this page is told to get tested rather than to buy something.
- In vitro Occurrence of testosterone and other sex hormones in pollen of Pinus species (1971) Trace androgens present in pine pollen. This 1971 chemistry finding carries almost the entire hormonal marketing claim, and no human trial has ever tested it as an outcome.
- Animal study Antioxidant and hepatoprotective effects of pine pollen in animal models (2012) Consistent animal antioxidant and liver-protective data. The real evidence base for pine pollen, and it is not a hormonal one.
- Case series Allergy to pine pollen: clinical characterisation and cross-reactivity (2009) Confirmed pine pollen as a genuine allergen with cross-reactivity among Pinus species. The one hard exclusion on the pine pollen report.
Glossary
Quick reference for the medical and technical terms used in this comparison.
- HPG axis Hypothalamic-Pituitary-Gonadal axis
- The three-stage feedback loop that controls testosterone: hypothalamus releases GnRH, pituitary releases LH and FSH, testes make testosterone. Every member of this ranking acts somewhere on it or on the cortisol brake attached to it.
- GnRH Gonadotropin-Releasing Hormone
- The hypothalamic signal at the top of the axis. Gonadorelin is the synthetic version, and it only works when delivered in pulses rather than continuously.
- LH Luteinizing Hormone
- The pituitary signal that tells the testes to produce testosterone. Suppressed by exogenous testosterone, which is the mechanism behind TRT's dependency cost.
- SHBG Sex Hormone-Binding Globulin
- The protein that binds testosterone and makes it unavailable. Tongkat ali's distinctive claim is lowering it, which raises free testosterone without making more total testosterone.
- Free testosterone Unbound testosterone
- The fraction not bound to SHBG or albumin, and the part that can actually act. A normal total testosterone with high SHBG can still mean low free testosterone, which is the case tongkat ali targets.
- TRT Testosterone Replacement Therapy
- Supplying the finished hormone rather than stimulating its production. The most effective member of this category and the seventh-ranked, for reasons the methodology note sets out.
- Hypogonadism Clinically low testosterone
- Low testosterone with symptoms, confirmed on two separate early-morning tests. The diagnostic standard in the Endocrine Society guideline, and the population every TRT trial on this page studied.
- Oligospermia Low sperm count
- The condition in the shilajit fertility trial. Relevant because it is also the predictable consequence of starting TRT without a fertility plan.
- KISS1R Kisspeptin receptor, formerly GPR54
- The receptor kisspeptin acts on to start the whole axis. Its discovery as the switch controlling puberty is why kisspeptin-10 is interesting despite thin data on the form sold.
- hCG Human Chorionic Gonadotropin
- An LH analogue acting directly on the testes. The better-tested tool for preserving fertility during TRT, and the source of the evidence gonadorelin's main use is extrapolated from.
- Cortisol The primary stress hormone
- Chronically elevated cortisol suppresses the HPG axis, which is how ashwagandha and phosphatidylserine qualify for a testosterone page without touching testosterone directly.
- Adaptogen Stress-modulating botanical
- A herb that blunts the stress response rather than stimulating or sedating. Ashwagandha is the classic example; tongkat ali is not technically one but behaves similarly.
First, and the only member of this category that beats testosterone itself at anything physiological: male fertility, 7.5 against TRT's 2.0. Pandit 2016 reported testosterone and DHEAS increases in healthy men after 500 mg a day for 90 days, and Biswas 2010 reported improved sperm parameters in oligospermic men. Pick it over tongkat ali when fertility is on the table or when you want the broadest mineral-resin case. Two real caveats: the flagship RCTs are small and funded by the branded ingredient supplier, and heavy-metal contamination is a genuine risk, so only purified product with lot-specific testing is acceptable.
