How Does Tesamorelin Compare to Sermorelin and CJC-1295?

Published 2026-07-13 · REVIVE Peptides Research Desk · 2 min read

Short answer: Tesamorelin, Sermorelin, and CJC-1295 are all GHRH-class research peptides that stimulate pulsatile endogenous growth-hormone release, but they differ substantially in half-life and clinical trial history: Tesamorelin (~26 min half-life) has completed Phase 3 trials, Sermorelin (~10-20 min) is a shorter native GHRH fragment, and CJC-1295 with DAC is long-acting (~6-8 days) via albumin binding.

All three belong to the GHRH-analogue class, meaning they act on the same pituitary GHRH receptor to stimulate the body's own pulsatile growth-hormone release, rather than supplying growth hormone directly. Where they differ is in structural modification and resulting half-life.

Tesamorelin carries an N-terminal stabilizing modification giving it roughly a 26-minute half-life, and it is the only one of the three to have completed a formal Phase 3 clinical trial programme (marketed pharmaceutically as Egrifta for a specific indication). Sermorelin is a shorter, unmodified GHRH(1-29) fragment with a short 10-20 minute half-life. CJC-1295 with Drug Affinity Complex (DAC) binds circulating albumin, extending its half-life dramatically to roughly 6-8 days — a fundamentally different exposure profile from the other two.

REVIVE LAB UAE currently stocks Tesamorelin specifically — Sermorelin and CJC-1295 are not part of its catalog. This comparison reflects general research literature on the GHRH-analogue class and is provided as research background only.
