§ 01 — Context

The longevity peptide stack centres on mitochondrial function (MOTS-c, humanin), telomerase modulation (epitalon), NAD+ precursors, and senescent-cell clearance pipelines. None are FDA-approved for longevity; all are research-grade.

We compare what's actually buyable today. Most of the longevity-peptide internet is theory; we focus on the 8-10 compounds that have real vendor offers and an emerging evidence base.

What to look for

01Whether the vendor publishes per-batch COAs

02Half-life and dosing protocol — longevity stacks are taken for months

03Stack interactions (epitalon × NAD+, MOTS-c × hgh)

04Cost per cycle, not per vial — most protocols run 8–12 weeks
