Epitalon testing round-up: what our latest samples measured
A close reading of the Epitalon evidence, without the marketing layer.
Dr. Alan Mercer··10 min read
Epitalon is a synthetic pineal tetrapeptide with a development status of "preclinical / limited foreign trials". The Institute rates the strength of its published evidence as limited. A tetrapeptide studied primarily in Russian longevity research; Western replication remains minimal.
This report covers the Epitalon samples processed in our most recent testing cycle. Every specimen was purchased anonymously at retail, transferred under chain-of-custody documentation, and analysed by an independent contract laboratory.
The Institute has independently tested 1 Epitalon sample from 1 company. 0% met their label claims on purity and content. Measured purity ranged from 93.7% to 93.7%, averaging 93.7%. Every specimen is published in full, including the laboratory that ran it.
The Peptide Institute is an independent research institute. We do not sell products, we do not accept vendor sponsorship, and we publish results that reflect badly on companies as readily as results that do not.
The two halves of the Wolverine stack just won a big vote from an FDA advisory committee. Here is what happened, why it matters, and the White House review that could come next.
23 samples, 12 sellers, one compound with almost no human evidence behind it. Measured purity ranged from 61% to 98.9%.
