Creatine Monohydrate earns 8.6/10 for strength and power because Lanhers 2015 reports Lower-limb global SMD 0.235 (small-to-moderate). Chilibeck 2017 points in the same direction, but route, dose, baseline status, and outcome tracking…
Read the Creatine Monohydrate report →The strongest strength and power argument for Essential Amino Acids is 7.8/10 because Hagiyama 2024 reports 12 RCTs; 622 patients; low-certainty improvement in patient-reported outcomes and very-low-certainty strength signal after lower-limb surgeries.…
Read the Essential Amino Acids report →Mechanistically, TRT (Testosterone Replacement Therapy) fits strength and power at 7.5/10 because Bhasin 1996 reports Classic androgen dose-response trial; supports anabolic mechanism but used supraphysiologic dosing in normal men, not standard TRT.…
Read the TRT (Testosterone Replacement Therapy) report →Grass-Fed Whey Protein scores 7.0/10 for strength power because protein sufficiency supports resistance-training adaptation better than most supplement categories. The strongest support comes from Shimomura Y. et al. 2006, but the practical…
Read the Grass-Fed Whey Protein report →Glycine strength power earns 6.8/10 because Soh 2024 anchors the most relevant signal. Glycine fits strength power because glycine participates in sleep signaling, glutathione, collagen, methylation, and nervous-system balance, depending on the…
Read the Glycine report →Strength Power is a 6.5/10 fit for Blood-Flow Restriction Training, based on the evidence summarized in Liu et al. 2024. Gronfeldt 2020 supports BFR as a viable strength stimulus, but heavy loading…
Read the Blood-Flow Restriction Training report →Taurine looks most relevant to strength and power at 6.5/10 because Tzang 2024 reports 25 RCTs and 1024 participants; lower SBP, DBP, fasting blood glucose, and triglycerides; no significant adverse-effect excess. Tzang…
Read the Taurine report →Full-Body EMS gets 6.5/10 for strength power; the evidence supports a narrow read. Kemmler 2021 and Rodrigues-Santana 2023 support strength gains in adults, but Puttner 2026 found no significant added jump, sprint,…
Read the Full-Body EMS report →Strength-power with Whole-Body Vibration scores 6.5/10, based on data from Peng et al. 2024. Whole-Body Vibration can serve as an adjunct to conventional resistance training, offering acute potentiation of muscle output without…
Read the Whole-Body Vibration report →Strength-power lands at 6.2/10 because Leal-Junior 2015 supports performance and recovery effects, but Red Light Therapy is stronger for recovery than acute force output. The likely value is better readiness, less soreness,…
Read the Red Light Therapy report →Shilajit strength power earns 6.0/10 because Keller 2019 anchors the most relevant signal. Shilajit fits strength power when purified resin is matched to hormones, sperm parameters, strength fatigue, bone markers, or energy…
Read the Shilajit report →Strength and power earn 6.0/10. Maximal sprinting recruits fast-twitch fibers and trains anaerobic power and rate of force development in a way steady cardio never does, and Burgomaster 2005 showed sprint work…
Read the Sprinting (Sprint Interval Training) report →A 5.8/10 for strength-power fits Tongkat Ali because Talbott 2013 supports direction more than certainty. The existing rationale points to this narrower claim: the cited study reported lean-mass and strength gains in…
Read the Tongkat Ali report →TB-500 (Thymosin Beta-4 Fragment) earns 5.5/10 for strength power; this is a targeted fit score. Strength-power benefits are indirect: faster injury recovery may preserve training continuity. There is no direct strength, hypertrophy,…
Read the TB-500 (Thymosin Beta-4 Fragment) report →On strength-power, Infrared Sauna deserves 5.5/10 because Oosterveld 2009 makes the claim plausible but incomplete. The existing rationale points to this narrower claim: Infrared sauna is not a direct strength ergogenic. It…
Read the Infrared Sauna report →Strength scores 5.5. Carrying 20 to 45 lb over distance, especially uphill or on stairs, loads the legs, hips, and posterior chain enough to build muscular endurance and modest strength in untrained…
Read the Rucking (Weighted Walking) report →On strength-power, Ca-AKG (Calcium Alpha-Ketoglutarate) deserves 5.5/10 because Demidenko 2021 makes the claim plausible but incomplete. The existing rationale points to this narrower claim: Indirect support from frailty and muscle-health mechanisms, but…
Read the Ca-AKG (Calcium Alpha-Ketoglutarate) report →Electrolytes's 5.0/10 strength-power score starts with Borra 2025, then gets narrowed by the evidence gap. The existing rationale points to this narrower claim: this verified source supports the direction that meaningful dehydration…
Read the Electrolytes report →PEMF (Pulsed Electromagnetic Field Therapy) fits strength power at 5.0/10 when the baseline problem is real. PEMF is not a primary strength tool. Any strength or power benefit is likely secondary to…
Read the PEMF (Pulsed Electromagnetic Field Therapy) report →The strength power case for Ashwagandha lands at 5.0/10 because the evidence points to a plausible use case without proving a universal response. Ferreira et al. 2025 is the best anchor here…
Read the Ashwagandha report →Strength scores 5.0/10 because Kumar 2023 reported significant grip-strength and chair-rise improvements in older adults, a genuine functional endpoint. The signal is real but limited to small trials in an older, glutathione-depleted…
Read the GlyNAC (Glycine + N-Acetylcysteine) report →For readers prioritizing strength power, Ephedrine scores 5.0/10 today. Jacobs 2003 resistance training study (n=13 males) showed first-set leg press reps improved from 13 to 19 with caffeine plus ephedrine, but effect…

Head-to-head reports and category rankings that name a winner on this use case.
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…
Shilajit scores 7.4 and ashwagandha 6.8, but that gap is the least useful number here. These two do different jobs. Shilajit is the mineral and androgen play: male…
Spermidine scores 7.6 and urolithin A 6.5, and they clean up different messes. Spermidine drives broad autophagy: autophagy 8.0, cardiovascular 7.8, longevity 7.5. Urolithin A drives selective mitophagy…
Ashwagandha scores 6.8 and tongkat ali 7.0, so the overall numbers do not decide it. Pick ashwagandha when stress, anxiety, or sleep is the complaint: its subratings there…
Metformin scores 6.9 and berberine 6.8, so the gap is meaningless. Metformin owns blood sugar with decades of outcome trials behind it. Berberine owns fatty liver, needs no…
Whey scores 8.3 and collagen 7.6, but they do different jobs. Whey is a complete protein that builds muscle. Collagen has no tryptophan, so it cannot. Pick whey…
Creatine Monohydrate, at 8.6 out of 10 for strength and power. Creatine Monohydrate earns 8.6/10 for strength and power because Lanhers 2015 reports Lower-limb global SMD 0.235 (small-to-moderate).
Of the top-scoring options, Glycine is the least expensive at about $2 a month, scoring 6.8 out of 10 for strength and power.
