Epitalon

Emerging

Also known as: Epithalon · Ala-Glu-Asp-Gly

A synthetic tetrapeptide associated with pineal peptide research and aging biology conversations. Evidence is largely historical/preclinical with limited modern RCT coverage.

Longevity / aging Sleep / recovery adjunct Recovery

Mechanism (plain language)

Linked in older literature to telomerase and pineal regulatory hypotheses. Mechanistic certainty in humans is low.

What research suggests

Russian and preclinical literature discusses geroprotective and circadian themes. Independent, large modern trials in athletic populations are lacking.

Uncertainties & risks

Longevity marketing often outruns reproducible evidence. Translation, replication, and product identity issues are significant. Treat as curiosity for diligence, not established practice.
