Sermorelin

GHRH(1-29) — the original, gentler GHRH research peptide. Milder than Tesamorelin.

Sermorelin is the original GHRH fragment — just the first 29 amino acids of natural growth-hormone-releasing hormone, the minimum needed to do the job. It's the gentlest, most physiologic option in the family: it nudges your pituitary rather than hammering it, which makes it a popular entry point for people who mainly want better sleep and recovery without pushing GH hard. The flip side of that gentleness is a very short half-life and milder effects than Tesamorelin, so it's best understood as the easy-going starter GHRH.
