Explained simply

Epitalon is a peptide — a short chain of amino acids. It is not an approved medicine. Products sold online labelled “for research use only” are not checked by FDA for what they contain.

What it's being researched for

Every claim about Epitalon will sit in exactly one of these boxes, so you can see how strong it is:

  • Established medical useApproved by FDA for a specific condition
  • Human clinical researchStudies in people
  • Animal researchStudies in animals only
  • Laboratory researchCells or tissue in a dish
  • Anecdotal claimsPersonal stories, not studies
  • Unsupported claimsClaims with no study behind them

The sorted list of claims hasn't passed scientific review yet, so we don't show it. Why?

How it works

A simple explanation of how it works hasn't passed scientific review yet, so we don't show it. Why?

What the evidence actually shows

Each study will show its type, size, who was studied, what was found, its limits, its date and a link to the original.

The study list hasn't passed scientific review yet, so we don't show it. Why?

Safety and limitations

For unapproved compounds, the honest answer is usually that long-term safety in people is unknown.

A sourced safety summary hasn't passed scientific review yet, so we don't show it. Why?

Approval and regulatory status

Compounding under review

Not approved. FDA reviews and advisory votes are steps in a process — only an FDA approval means a product is approved.

    FDA announces removal of 12 peptides from the Category 2 list

    FDA published a notice scheduling a Pharmacy Compounding Advisory Committee meeting and said it would remove twelve peptides from Category 2 of its interim 503A bulks list after nominators withdrew their nominations.

    What this doesn't mean: Removal from Category 2 does not make a substance eligible for compounding, and it is not FDA approval.

    Advisory vote

    PCAC recommends Epitalon and Semax; does not recommend DSIP

    Epitalon was recommended 7–4 (1 abstention) and Semax 8–5 (1 abstention). Emideltide (DSIP) was not recommended, 6–7 (1 abstention).

    What this doesn't mean: A 'yes' vote is not approval and does not yet permit compounding; a 'no' vote is not a safety finding against a substance.
