- GH secretagogues are among the most widely researched peptide classes — and the most frequently confused. Ipamorelin, CJC-1295, sermorelin, and GHRP-6 all stimulate growth hormone release but through fundamentally different mechanisms, with different receptor targets, different GH pulse profiles, different selectivity, and different appropriate research applications. This guide provides a systematic comparison to inform correct research tool selection for GH axis biology.
