Epitalon: what it is, what the evidence says, and its real status
A short peptide studied for sleep and circadian support.
Short version: the boldest longevity folklore in the peptide world. We separate folklore from evidence, which keeps it firmly in education-and-waitlist territory.
Can you actually get it?
Plain-English verdict: Waitlist.
Regulatory status: Under PCAC review · PCAC · Jul 23–24, 2026.
Not available to prescribe today. On the PCAC agenda; the claims outrun the data, so it stays education and waitlist only.
How does Epitalon work?
A tetrapeptide proposed to influence the pineal gland and telomerase activity.
What it does — and what it does not do
What it does: Studied for sleep, circadian, and general longevity-support interest.
What it does not do: It is not proven to extend how long you live, and it is not available to prescribe today.
How honest is the evidence?
Evidence grade D — preclinical or animal-dominant; no controlled human efficacy data. Read our grading methodology for what each grade means.
What we still don't know: Most data is older and methodologically limited; claims outrun the evidence.
WADA status: Not prohibited.
How it is taken
No established human clinical dosing; research-stage.
Who should not take it
Not characterized in humans; lifespan and telomerase claims are unproven.

Compounded medications are not FDA-approved. We keep two signals separate and never collapse them: whether you can get something, and what the rule currently says. See the live FDA Peptide Tracker or the knowledge base.
