Peptide & blend guide

The short version

Why people discuss it
Discussed for longevity, telomere-related claims and sleep/circadian rhythm support. Community interest does not establish benefit or a suitable treatment.
What it is
Epitalon, also transliterated epithalon, is the synthetic tetrapeptide Ala-Glu-Asp-Gly.
Biggest caution
Sequence names and product spellings do not establish pharmaceutical identity. The selected evidence does not support a validated lifespan, sleep or age-related treatment claim in humans.
Stack context
Related profiles reflect adjacent community topics or biological context. They do not establish combination benefit, compatibility or a validated regimen.

Dose and frequency reference

Reference only — not a recommendation. Amounts describe source-specific community examples, selected study regimens or the named product label. They do not establish safety, effectiveness, product identity, or a suitable dose for any person. Never convert mg, mcg, or IU into syringe “units” without the exact product concentration.

Sources report different amounts or schedules; the reference below is a named example, not a consensus.

Subcutaneous injection

Community reference · Not clinical guidance
Amount
5 mg
Frequency
Once daily
Duration / phase
20 days; reported breaks of 4–6 months

This example appears in both new publishers. Older community synthesis uses 0.5–1 mg/day and disputes transfer of epithalamin extract doses to synthetic epitalon. Repetition does not resolve that evidence disagreement or establish safety. Reference only; this does not establish safety, effectiveness or individual suitability.

Subcutaneous injection — lower reported convention

Community reference · Not clinical guidance
Amount
500 mcg–1 mg
Frequency
Once daily
Duration / phase
10–20 days

Older community convention for synthetic epitalon. It conflicts with the 5–10 mg range in the new sources; no dose-finding study settles the difference.
