Epitalon
Epitalon scored 6.7 / 10 (👍 Worth trying) on the BioHarmony scale as a Substance → Peptide.
Epitalon is a synthetic AEDG tetrapeptide with in vitro telomerase and telomere data, animal lifespan signals, and Russian pineal-peptide melatonin studies. The score stays 6.8/10 because the strongest human claims are not independently replicated, and the 2025 Al-dulaimi paper adds mechanistic support plus cancer-cell ALT caution.
What is Epitalon?
Epitalon, also called Epithalon or AEDG, is a synthetic four-amino-acid peptide modeled after epithalamin, a pineal-gland peptide extract from the Russian bioregulator tradition. Its core claim is unusual: a short peptide cycle may influence telomerase, telomere length, melatonin rhythm, and age-related neuroendocrine decline. Khavinson 2003 reported telomerase activity and telomere elongation in cultured human somatic cells, while Al-dulaimi 2025 independently found telomere-length extension in normal epithelial and fibroblast cells and in breast-cancer cell lines.
That sounds stronger than it is. The telomere evidence is still in vitro, not a human telomere trial. The human circadian evidence is also messier than older Epitalon writeups implied. The audit confirmed that several v0.x PubMed links were wrong, and the most source-stable elderly melatonin paper is Korkushko 2004, which studied epithalamin, the pineal extract precursor, rather than clean synthetic Epitalon.
Animal evidence adds signal but not certainty. Anisimov 2000 supports 11-16% mean lifespan extension in Drosophila. The SHR mouse paper supports tumor and maximum or last-survivor lifespan findings, but it should not be summarized as a clean mean-lifespan win. This is why Epitalon remains a 6.8/10: interesting, relatively low-burden, and mechanistically sharp, but still resting on narrow and uneven evidence.
The practical intervention is usually a short subcutaneous peptide cycle, not daily indefinite supplementation. Typical community dosing is 5-10 mg/day for 10-20 days, repeated once or twice per year. Sublingual and nasal versions exist, but they are protocol experiments rather than clinical evidence.

Upside Rationale
Epitalon earns a solid efficacy read once its real-world record is credited the way Russian clinical-record peptides like bromantane and semax are credited, rather than discounted for lacking a Western trial. The most-cited human-adjacent signal is telomere biology, where Khavinson 2003 reported telomerase activation and telomere elongation in human somatic cells, work that Al-dulaimi 2025 independently extended in human cell lines. Decades of multi-year clinical and geroprotective use under the Khavinson program, summarized in Anisimov and Khavinson 2010, report improved vitality and aging biomarkers in elderly cohorts. Telomerase is the mechanism, but Epitalon's claimed longevity and vitality outcomes are credited at real-world strength here, not collapsed to a pure surrogate, which puts Epitalon clearly above the midpoint on efficacy.
Epitalon shows real breadth across several aging-related systems, which is one of the most genuinely encouraging parts of its profile. The peptide carries signals spanning telomere biology, pineal melatonin rhythm, antioxidant defense, retinal cell biology, and gene expression. Kozina 2007 supports antioxidant-system effects in aged tissue, and Khavinson 2020 supports AEDG-peptide gene-expression activity in neurogenesis models. That multi-system reach is what makes Epitalon compelling to longevity self-experimenters who want one bioregulator touching many aging pathways. The honest temper on Epitalon is translation depth: several arms are cell, animal, or single-lineage clinical signals rather than broadly replicated outcomes, so the breadth is real and well documented while the strength of each individual arm still varies.
Epitalon's evidence base is a real, multi-year clinical and real-world record that simply concentrates in one research tradition, and it is credited consistently with the other Russian clinical-record peptides rather than penalized for the absence of a large randomized trial. The Khavinson 2003 telomere work, the Anisimov and Khavinson 2010 summary of the geroprotective clinical program, and the Al-dulaimi 2025 independent confirmation in human cell lines, all cited above, anchor that record. The single-group, single-lineage concentration of the flagship data is why confidence in Epitalon stays Low, but that concentration is treated as a confidence ceiling, not an evidence floor. The body of work justifies cautious testing on its own merits rather than being discounted simply for not matching a Western trial format.
Epitalon is a slow, cumulative intervention, so anyone expecting a fast subjective effect should reset expectations. The protocol is cycle-based, typically a short course of injections repeated once or twice yearly, and the proposed benefits work through telomere, pineal, and circadian biology that does not announce itself quickly. Korkushko 2004 measured pineal melatonin-producing function before and after pineal-peptide treatment in older adults, the kind of marker that shifts over a course rather than overnight. Epitalon offers no stimulant-like, same-day feedback, and its headline telomere and longevity effects are not personally observable within a single cycle. That slow onset is why speed is the weakest dimension in Epitalon's upside, even though the underlying clinical record is genuinely credited elsewhere.
Epitalon's durability is attractive because the documented effects are described as persisting between courses, not just during them. Dosing is cyclical rather than daily and indefinite, so a single short course followed by months off is far easier to sustain than most everyday supplements, which is a meaningful adherence advantage. The Russian clinical model reflected in the Anisimov and Khavinson 2010 geroprotective record reports effects that carry across the interval between courses rather than reverting the moment dosing stops. Credited consistently with the other clinical-record peptides, this between-course persistence is treated as a real durability signal for Epitalon rather than discounted. The remaining caveat is that long-term independent follow-up outside the originating lineage is still thin, which keeps the durability read confident but not maximal.
Epitalon fits a broad range of users with relatively few responder or interaction constraints, which lifts its bioindividuality score. The peptide does not depend on a specific genotype, has no well-documented drug-interaction minefield, and is most rationally targeted at older adults with age-related pineal decline, disrupted sleep timing, or low nighttime melatonin. Younger adults with intact circadian function have a weaker rationale because Epitalon's clearest human signal is rhythm and aging-biomarker restoration rather than performance enhancement. Cancer history, pregnancy, drug-tested athletics, and tolerance for gray-market sourcing meaningfully change the calculus. In practice Epitalon suits advanced longevity experimenters more than beginners, but for its intended older population it is broadly applicable with low individual-variability friction.

Downside Rationale
Epitalon carries genuinely low intrinsic safety risk, and the corrected read treats it as a benign, well-tolerated peptide rather than a dangerous one. Published Russian and community use does not show a clear fatal, organ-failure, or severe systemic adverse-event pattern at standard injectable doses, so Epitalon has no intrinsic severe-harm floor. The class-wide cancer worry from telomerase activation is theoretical and is not supported as a demonstrated harm. The one real caveat is extrinsic, not intrinsic: the FDA lists epitalon among bulk substances that may pose compounding risks tied to peptide impurities and sourcing, which is a gray-market purity problem rather than a property of the molecule. Use a verified source and Epitalon's safety profile is reassuring.
Epitalon's side-effect profile is near the benign floor, with only minor, self-limiting issues reported. The common practical complaints are injection-site redness, transient swelling, and occasional mild fatigue, and no verified source shows a meaningful gastrointestinal, cardiovascular, neurological, or psychiatric side-effect pattern. This is genuinely one of the cleaner side-effect profiles among injectable peptides. The honest qualifier is evidence capture rather than hidden danger: because most Epitalon use happens through gray-market channels, it is not monitored by large pharmacovigilance systems, so rare events would be underreported. Even allowing for that, the known side-effect burden of Epitalon is small, and the low score reflects a benign tolerability picture rather than a lack of investigation masking serious problems.
Epitalon sits at a moderate financial cost, cheaper than most peptide interventions but not trivial as a recurring expense. Purchased as gray-market injectable powder, a common 10 mg vial often runs roughly 30 to 80 dollars, so a short course can be relatively inexpensive next to advanced diagnostics, devices, or prescription longevity drugs. The catch with Epitalon is that price and authenticity are linked: third-party certificate of analysis, cold-chain handling, and vendor reliability all add real cost or real risk. Sublingual protocols get far more expensive because users take 50 to 100 mg per day to offset poor oral bioavailability, without clinical evidence that the extra spend buys results. Budget Epitalon as a modest, repeating outlay where paying for verified quality is the smart move.
Epitalon imposes a moderate execution burden concentrated into short windows rather than a constant lifestyle tax. Subcutaneous use requires sourcing the peptide, reconstituting it, refrigerating it, maintaining sterile technique, and self-injecting daily across a 10 to 20 day cycle. That is clearly more involved than swallowing a capsule, and the injection requirement is a real friction point for needle-averse users. The redeeming structure is that Epitalon is cyclical: after the active course, users typically take months off, so the annual time commitment stays low. The effort score for Epitalon reflects short-term, in-cycle friction around injections and handling rather than an ongoing daily routine, which keeps it well below the burden of device-based or strict-diet protocols.
Epitalon's opportunity cost is moderate because better-supported substitutes exist for its most practical endpoints. For sleep and circadian complaints, low-dose melatonin, morning outdoor light, CBT-I, caffeine timing, and consistent sleep scheduling all carry far stronger human evidence than Epitalon. For longevity, rapamycin, metformin, resistance training, cardiorespiratory fitness, and metabolic-health fundamentals are more defensible places to spend effort and money. Epitalon's unique angle is telomere and pineal bioregulation, credited here on its real-world clinical record, but that record concentrates in one research tradition, so committing to it before the basics risks displacing higher-yield work. The reasonable sequencing is to use Epitalon as an add-on after fundamentals are in place, not as a substitute for them.
Epitalon has no known dependency or withdrawal pattern, which puts it near the bottom of the risk scale on this dimension. The course-based protocol structurally avoids the daily, indefinite dosing that drives most dependence problems, and no verified mechanism suggests receptor downregulation, endocrine suppression, rebound insomnia, or a withdrawal syndrome when Epitalon is stopped. If benefits occur, they would be expected to fade gradually as the biological signal fades rather than crash below baseline. There is no craving, escalation, or physiological need to keep using Epitalon. This earns a true baseline dependency score, and it is one of the clearer points in the peptide's favor: stopping Epitalon simply means not starting the next cycle.
Epitalon is highly reversible at the practical level, which keeps its downside on this dimension low. A short peptide cycle can be stopped at any time without tapering, and Epitalon is not a permanent implant, ablation, or gene therapy, so discontinuation carries no structural commitment. The only nuance worth flagging is not day-to-day reversibility but the theoretical question of whether telomerase or ALT-related activity could matter in cancer-prone tissue, and that concern is properly handled under safety rather than reversibility. For the large majority of users, stopping Epitalon simply means declining to repeat the next cycle, with no lingering intervention to undo, which is why reversibility scores near the floor.
Is Epitalon worth it?
Epitalon is a 6.7 / 10 fit for people using longevity, sleep quality, and healthspan as a measured experiment, not a belief-based staple. The best anchors are Al-dulaimi et al. 2025, which reports independent in vitro study and normal epithelial and fibroblast cell telomere extension plus cancer-cell ALT activation caution, and Khavinson, Bondarev, Butyugov 2003, which reports in vitro human fetal fibroblast telomerase and telomere finding and preclinical clinical evidence. That gives Epitalon a real signal, but the report should stay narrow because responder fit, baseline status, and outcome tracking drive the practical value. Use Epitalon when the target is specific, measurable, and worth the tradeoff. Skip or stop Epitalon when the expected symptom, lab, or performance marker stays flat.
✅ Best for: Adults over 55 with documented age-related sleep disruption, low nighttime melatonin, or interest in cyclical pineal-axis support; advanced longevity self-experimenters who already have exercise, sleep hygiene, metabolic health, protein intake, and stronger geroprotective options handled; people who understand that Khavinson 2003 and Al-dulaimi 2025 are cell evidence, not human lifespan proof; and researchers comfortable with gray-market peptide sourcing, third-party testing, and low-confidence self-experimentation.
❌ Avoid if: You are pregnant, breastfeeding, under 18, actively fighting cancer, or have a strong cancer history without clinician oversight. Avoid Epitalon if you expect proven human telomere elongation, human lifespan extension, or a first-line sleep treatment. Tested athletes should avoid it because WADA S0 can apply to non-approved pharmacological substances. Also avoid if you are unwilling to inject, since sublingual and nasal protocols are unvalidated, or if you cannot verify vendor purity, sterility, and storage conditions.

What is Epitalon best for?
The overall BioHarmony score reflects the intervention's primary evidence profile. These subratings are independent assessments per use case.
Longevity / Lifespan: 6.5/10
Score: 6.5/10The longevity case for Epitalon lands at 6.5/10 because the evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor here because it reports independent in vitro study and normal epithelial and fibroblast cell telomere extension plus cancer-cell ALT activation caution. Al-dulaimi et al. 2026 adds context, but the exact longevity outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
Sleep Quality: 6.5/10
Score: 6.5/10For sleep quality, Epitalon earns 6.5/10 because the evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor here because it reports independent in vitro study and normal epithelial and fibroblast cell telomere extension plus cancer-cell ALT activation caution. Al-dulaimi et al. 2026 adds context, but the exact sleep quality outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
Healthspan: 5.5/10
Score: 5.5/10Population fit explains the 5.5/10 healthspan score for Epitalon because the evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor here because it reports independent in vitro study and normal epithelial and fibroblast cell telomere extension plus cancer-cell ALT activation caution. Al-dulaimi et al. 2026 adds context, but the exact healthspan outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
Circadian Rhythm / Chronobiology: 6.5/10
Score: 6.5/10For circadian rhythm, Epitalon earns 6.5/10 because the evidence points to a plausible use case without proving a universal response. Korkushko et al. 2004 is the best anchor here because it reports source-verified epithalamin melatonin paper and relevant precursor evidence, not clean synthetic Epitalon randomized trial proof. Al-dulaimi et al. 2025 adds context, but the exact circadian rhythm outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
Telomere / DNA Repair: 5.5/10
Score: 5.5/10The main limitation behind Epitalon's 5.5/10 telomere dna score is that the evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor here because it reports independent in vitro study and normal epithelial and fibroblast cell telomere extension plus cancer-cell ALT activation caution. Al-dulaimi et al. 2026 adds context, but the exact telomere dna outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
Geriatric / Aging Population: 6.5/10
Score: 6.5/10Mechanistically, Epitalon scores 6.5/10 for geriatric because the evidence points to a plausible use case without proving a universal response. Kozina et al. 2007 is the best anchor here because it reports old-rat antioxidant-system evidence for pineal geroprotective peptides. Al-dulaimi et al. 2025 adds context, but the exact geriatric outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
Sleep Architecture (Deep/REM): 5.5/10
Score: 5.5/10Mechanistically, Epitalon scores 5.5/10 for sleep architecture because the evidence points to a plausible use case without proving a universal response. Al-dulaimi et al. 2025 is the best anchor here because it reports independent in vitro study and normal epithelial and fibroblast cell telomere extension plus cancer-cell ALT activation caution. Al-dulaimi et al. 2026 adds context, but the exact sleep architecture outcome still needs baseline-matched tracking. That makes Epitalon most defensible as a short, measured trial for someone with a clear target. Track the relevant symptom, lab, or performance marker, then stop Epitalon if the expected change does not appear.
| Use Case | Score | Summary |
|---|---|---|
| ○ Eye / Vision Health | 4.0 | Russian clinical and cell-literature interest in retinal tissues gives Epitalon a stronger eye-vision signal than most categories. Khavinson 2003 reported peptide effects on retinal and pigmented epithelial cell proliferative activity, but v1.0 tempers this because clinical ophthalmology claims were not cleanly source-verified. |
| ○ Antioxidant / Oxidative Stress | 4.0 | Antioxidant status improvement is one of the better-supported secondary signals. Kozina 2007 specifically investigated antioxidant properties of pineal geroprotective peptides, but the strongest evidence remains animal and Russian-lab centered rather than independently replicated human data. |
| ○ Hormonal / Endocrine | 3.5 | Melatonin secretion restoration in elderly adults is the most relevant hormonal signal, but the audit found the human citation trail blends Epitalon with epithalamin. Korkushko 2004 confirms pineal extract modulation of nocturnal melatonin, so the direction is supportive but not clean direct Epitalon evidence. |
| ○ Cellular Senescence | 3.5 | Telomerase activation and telomere effects point toward cellular-senescence relevance, but no human senescence-marker RCT exists. Khavinson 2003 and Al-dulaimi 2025 support cell-line mechanisms; they do not prove reduced p16, SASP, tissue aging, or clinical senescence burden. |
| ○ Immune Function | 3.0 | Thymus restoration and T-cell normalization are mainly aged-animal and Khavinson-lab claims, not verified human immune RCT outcomes. The 2010 Anisimov and Khavinson peptide-bioregulation review supports broad immune-aging context, but v1.0 keeps the score modest because independent human immune endpoints are absent. |
| ○ Anti-Inflammatory | 3.0 | Antioxidant and oxidative-stress findings imply possible downstream anti-inflammatory effects, but direct inflammatory-marker evidence is thin. No verified human Epitalon trial measured CRP, IL-6, TNF-alpha, pain inflammation, or disease-specific inflammatory outcomes. |
| ○ Energy / Fatigue | 3.0 | Quality-of-life improvements in Russian elderly peptide literature included energy and vitality-like outcomes, but objective energy-metabolism endpoints are absent. Any energy effect is likely secondary to sleep or circadian rhythm rather than direct mitochondrial enhancement. |
Frequently Asked Questions
How does Epitalon actually work in the body?
Epitalon appears to affect telomere biology in cell models and pineal signaling in the Russian peptide-bioregulator literature. Khavinson 2003 reported telomerase activation and telomere elongation in human somatic cells, while Al-dulaimi 2025 found telomere extension in normal and cancer cell lines. Human melatonin evidence is less clean because audit-confirmed sources often involve epithalamin, the pineal extract precursor.
What dose of Epitalon should I take, and does the route matter?
The most defensible protocol is subcutaneous 5-10 mg/day for 10-20 days, repeated one or two times per year. That matches the Russian clinical-style protocol lineage better than oral or sublingual use. Sublingual users often take 50-100 mg/day to compensate for low peptide bioavailability, but no clinical trial validates that route. Nasal spray dosing is also anecdotal.
What does the human evidence actually show for Epitalon?
Human evidence for Epitalon is weaker than most marketing implies. The strongest source-verified human-adjacent melatonin evidence is Korkushko 2004, but that paper studied epithalamin, a pineal extract, not clean synthetic Epitalon. Direct telomere evidence remains in vitro. No independent Western RCT, Cochrane review, or major medical-society guideline supports Epitalon for aging or sleep.
Is Epitalon safe to use long-term?
Epitalon has a quiet published side-effect profile, but long-term safety is not proven. Russian literature and community use do not show a clear severe adverse-event pattern at 5-10 mg injectable doses, yet trial sizes are too small to rule out rare harms. FDA lists epitalon among bulk drug substances that may present compounding safety risks, including immunogenicity, impurities, aggregation, and limited route-specific safety information.
Who should avoid Epitalon?
Avoid Epitalon if pregnant, breastfeeding, under 18, actively fighting cancer, or at high cancer risk without clinician oversight. Al-dulaimi 2025 found cancer-cell telomere extension through ALT activation, which does not prove harm but strengthens caution. Tested athletes should also avoid gray-market Epitalon because WADA's S0 category can apply to non-approved pharmacological substances.
How fast should I expect to notice effects from Epitalon?
Sleep and circadian effects, if they happen, are the only effects you could plausibly notice within days to weeks. Russian pineal-peptide protocols often use a 10-day course, and Korkushko 2004 studied melatonin rhythm before and after epithalamin. Telomere, healthspan, and lifespan claims cannot be meaningfully self-assessed during one cycle.
How does Epitalon compare to simply taking melatonin?
Melatonin is the better-supported sleep tool; Epitalon is the more speculative upstream strategy. Melatonin directly supplies the hormone, is cheap, legal, and supported by a much larger Western evidence base. Epitalon's proposed advantage is restoring pineal output after a short cycle, but no head-to-head trial has compared Epitalon against low-dose melatonin for sleep, circadian entrainment, or long-term endocrine outcomes.
Does Epitalon extend telomeres in humans, or only in cells?
Epitalon telomere evidence is cell evidence, not human clinical proof. Khavinson 2003 reported telomerase activation and telomere elongation in cultured human somatic cells. Al-dulaimi 2025 independently supported telomere-length effects in normal cell lines and cancer cell lines. No published human trial has shown longer leukocyte telomeres after an Epitalon cycle.
What could change Epitalon's score?
BioHarmony scores are living assessments. New research, regulatory changes, or personal context can shift the score up or down. These are the most likely scenarios that would change this intervention's rating.

What does the evidence say about Epitalon?
Evidence on this intervention is summarized across three complementary streams: contemporary clinical research, pre-RCT-era pharmacology and observational use, and the traditional medical systems that documented it first. Convergence across streams signals higher confidence; divergence is surfaced honestly.
Modern Clinical Research
Confidence: Limited
On the Outliyr Podcast, Phil Micans noted: “Probably the most famous name in this field is epitalon, which is the pineal peptide... to me that could be the most important of all 21.” (EP106).

Holistic Evidence for Epitalon
The three lenses converge on the pineal gland, circadian aging, and telomere biology, but they disagree on certainty. Russian historical use treats the peptide-bioregulator framework as clinically meaningful. Modern evidence confirms some cellular mechanisms and animal signals while leaving human outcomes unresolved. The honest synthesis is that Epitalon is a promising, low-confidence longevity peptide: most interesting after stronger sleep, exercise, metabolic, and geroprotective fundamentals are already handled.
What to Track If You Try This
These are the data points that matter most while running a 30-day Experiment with this intervention.
How to read this section
- Pre
- Test or score before starting the protocol. Anchors a baseline.
- During
- Track while running the protocol so you can see if anything is changing.
- Post
- Re-test after a full cycle to confirm the change held.
- Up
- The marker should rise. For most positive outcomes, that is a good sign.
- Down
- The marker should fall. For most positive outcomes, that is a good sign.
- Stable
- The marker should hold steady. Big swings in either direction are a yellow flag.
- Watch
- Direction depends on dose, timing, and your baseline. Pay close attention to the trend.
- N/A
- No expected direction. The entry is there to anchor a baseline reading.
- Primary
- The Pulse dimension most likely to shift. Track this first.
- Secondary
- Also relevant, but a smaller or less consistent shift. Track if Primary is unclear.

See all ratings →📊 How BioHarmony scoring works
BioHarmony translates a weighted expected-value calculation into a reader-facing 0–10 score. Tier bands: Skip 0–2.9, Caution 3.0–4.4, Neutral 4.5–5.7, Worth Trying 5.8–6.9, Strong Recommend 7.0–8.7, Top-tier 8.8–10.0.
Harm-type downsides (safety risk, side effects, reversibility, dependency) carry a 1.4× precautionary multiplier. Harm weighs more than benefit. Opportunity-type downsides (financial cost, time/effort, opportunity cost) are subtracted at face value.
Use case subratings are independent assessments of how well the intervention addresses specific health goals. They are not components of the overall score. Each subrating reflects the scorer's judgment based on use-case-specific evidence, safety, and effect sizes.
Every dimension is evaluated on a 1–5 scale, and the baseline (1) is subtracted before weighting. A perfect intervention with zero downsides contributes zero penalty rather than a residual floor, so top-tier scores are actually reachable.
EV = Upside − Downside
EV = 2.185 − 0.797 = 1.388
Formula v2.0 maps EV = 0 to score 5.0. Above neutral, EV = +4.00 reaches 10.0; below neutral, EV = −5.36 reaches 0.0. Both sides use the full 5-point half-scale.
Score = 5 + (1.388 / 4.00) × 5 = 6.7 / 10
