Independent · Evidence-graded

The peptide evidence, graded. Not sold.

Mechanism, human data, and honest uncertainty for every longevity peptide that matters. Every claim graded by strength of evidence. Nothing for sale.

Independent and educational. We grade the evidence and flag where it's animal-only.

Which peptide fits your goal?

Four quick questions, then a plain-English, sourced match — no fluff.

Epitalon

GHK-Cu

Copper tripeptide-1

GHK-Cu

A naturally occurring copper-binding tripeptide with solid evidence for topical skin benefits — but injectable/systemic 'longevity' use is largely unstudied in humans.
