Epitalon
Also known as Epithalon · AEDG peptide
Evidence comes from cell culture or biochemical assays. This can establish that a compound does something to cells in a dish. It establishes nothing about what it does in a living body.
What it is
A four-residue peptide developed in the Soviet Union and later Russia, derived from work on pineal gland extracts. It is widely marketed on longevity claims that its evidence base does not support.
How it is thought to work
Proposed to influence telomerase activity and circadian regulation. The mechanistic account is not well established outside the group that developed it.
What the studies found
-
Reports of telomerase activation in cell culture
Laboratory studies from the originating research programme reported increased telomerase activity and extended replicative capacity in cultured human cells.
-
Claims of extended lifespan in rodents and humans
Long-running Russian studies reported reduced mortality in rodents and, in one much-cited report, in elderly human participants. These have not been independently replicated.
What the evidence does not show
- Essentially the entire evidence base comes from one research programme, published largely in Russian-language journals, and has not been replicated by independent groups.
- The human studies most often cited do not meet contemporary standards for randomisation, blinding or reporting.
- Telomerase activation is not straightforwardly desirable. It is a recognised feature of many cancers, and the long-term consequences of pharmacologically increasing it are unknown.
- Of everything on this site, this has the largest gap between marketing claims and credible evidence.
Reported risks and adverse effects
- No adequate human safety data from studies that would satisfy a regulator.
- Theoretical concern regarding telomerase activation and neoplasia is unresolved.
- Absence of reported harm in poorly designed studies is not evidence of safety.
