Lower numbers = closer to natural. Higher numbers = more enhanced.
Why this rating?
An endogenous hormone that regulates circadian timing, taken to improve sleep. It is a hormone in the strict sense, but it has no anabolic, androgenic or ergogenic action and does not touch the HPT axis. It does not raise the natural ceiling. Rated 1 (basically natty).
Overview
The most commonly used sleep aid, and relevant here because sleep is where recovery actually happens. The compounds people obsess over do far less than a consistently good night. It is also directly useful against the sleep disruption caused by several compounds in this archive, from late caffeine to trenbolone night sweats.
Important Warnings
- •Commonly sold at doses far above the ~4mg where the dose-response effect peaks
- •Morning grogginess usually means the dose is too high, not too low
- •It is a chronobiotic more than a sedative. Timing matters more than milligrams
- •Will not overcome stimulants taken too late in the day
- •Prescription-only in some countries despite OTC status in the US
- •Supplement-grade content can deviate from the label
Purpose & Use Cases
Reducing Time To Fall Asleep
The best-supported use. Meta-analysis of primary sleep disorders found melatonin significantly reduced sleep latency, with a weighted mean difference of 7.06 minutes, alongside increased total sleep time and improved sleep quality.
Circadian Realignment
Used at much lower doses and earlier timing to shift the body clock, for shift work, jet lag or delayed sleep phase. This is a different protocol from using it as a sleep inducer.
Offsetting Compound-Driven Sleep Disruption
Several compounds here degrade sleep: caffeine late in the day, stimulant fat-burners, and trenbolone's well-known night sweats and insomnia. Protecting sleep protects recovery.
Benefits
- Decreases sleep onset latency, increases total sleep time and improves overall sleep quality
- A dose-response meta-analysis found effects on sleep onset latency and total sleep time peaking at 4 mg/day
- Effects are modest but do not appear to dissipate with continued use
- No dependence or withdrawal syndrome of the kind associated with sedative hypnotics
- Very mild side-effect profile
- Cheap and available without prescription in many countries
Good to Know
The dose most people take is far too high
A dose-response meta-analysis found melatonin's effect on sleep onset latency and total sleep time peaking at around 4mg/day. Retail products are routinely sold at 10mg and higher. Beyond the peak you are adding grogginess, not sleep.
Timing beats dose
Melatonin is primarily a clock signal, not a sedative. Used as a sleep inducer it goes in 30 minutes before bed at 1-3mg. Used to shift the clock it goes in 2-3 hours earlier at 0.2-0.5mg. Escalating the dose is the wrong lever when the timing is wrong.
The effect is real but modest
The meta-analytic reduction in sleep latency was a weighted mean difference of about 7 minutes. That is a genuine effect and a small one. Melatonin is not a sleeping pill and will not overpower a stimulant taken too late.
Sleep is the recovery variable that actually matters
Most of the compounds in this archive are chasing recovery and growth. Sleep does more for both than nearly anything else here, and several compounds (trenbolone especially, plus late caffeine and stimulant fat-burners) actively degrade it.
Dosage Guidelines
| Experience Level | Dosage Range |
|---|---|
| Beginner | 0.5 – 1 mg/day |
| Intermediate | 1 – 3 mg/day |
| Advanced | 3 – 5 mg/day |
Two distinct protocols that are frequently confused. As a SLEEP INDUCER, 1-3mg administered 30 minutes before bedtime, increased slowly up to 5mg at night if there is no effect. As a CHRONOBIOTIC for shifting the body clock, a much smaller 0.2-0.5mg is given 2-3 hours before dim light melatonin onset, earlier and smaller, not larger. A dose-response meta-analysis found effects peaking around 4mg/day, so the 10mg and 20mg products widely sold are past the point of additional benefit. More melatonin is not more sleep; the common mistake is escalating the dose when the real problem is timing.
The short half-life of immediate-release melatonin is why it is much better at helping you fall asleep than at keeping you asleep. It has largely cleared by the middle of the night. Extended-release formulations exist for that reason.
Side Effects
Morning grogginess
commonResidual sleepiness on waking, most often from taking too large a dose or taking it too late at night.
Reduce the dose (this is usually a signal to go down, not up) and take it earlier relative to bedtime.
Vivid dreams
commonFrequently reported and generally harmless, though some find it disruptive.
Reduce dose if bothersome.
Headache / dizziness
uncommonOccasionally reported.
Usually resolves with a lower dose.
Supplement dose accuracy
commonSold as a supplement rather than a regulated medicine in many markets, so actual content can differ from the label. This matters more than usual here because the effective dose range is narrow and low.
Choose products with third-party testing.
General Mitigation Strategies
A benign supplement with a mild side-effect profile and no dependence pattern. The most common problem is self-inflicted: taking far more than needed. Products are widely sold at 10mg when the dose-response data peaks around 4mg, and grogginess is usually a signal to reduce rather than increase. If timing is the problem, no amount of extra milligrams will fix it.
Post Cycle Therapy (PCT)
No HPT axis interaction. No PCT implications.
How It Works
Melatonin is secreted by the pineal gland in response to darkness and acts on MT1 and MT2 receptors to signal biological night, lowering core temperature and promoting sleep onset. It is primarily a chronobiotic, a clock-setting signal, rather than a sedative, which is why timing relative to your intended sleep window matters as much as dose.
Hormonal & Androgenic Profile
N/A: a pineal hormone with no androgen receptor activity.
Not an aromatase or estrogen tool.
No adverse cardiovascular effect at typical doses.

Common Stacks
- Melatonin 1-3mg 30 minutes before bed for sleep onset
- Melatonin alongside trenbolone or stimulant cycles that disrupt sleep
- Fix stimulant timing before escalating melatonin dose
Legal Status
Sold over the counter as a dietary supplement in the US and many other countries. In parts of Europe, Australia and elsewhere it is a prescription medicine. Not a controlled substance.
Legal status varies by country and changes over time. This is a general summary, not legal advice.
WADA Status
Melatonin is not listed on the WADA Prohibited List and has no performance-enhancing action.
