Growth Hormone & Performance Peptides

Secretagogues and growth-factor analogues, split by where they act. GHRH analogues such as sermorelin and CJC-1295 work on the GHRH receptor; the GHRPs and ghrelin mimetics act at GHS-R1a; the IGF group sits downstream of both. That distinction matters for study design, because the three produce different release profiles and are rarely interchangeable. Blends that pair a GHRH analogue with a GHRP are stocked separately, pre-combined at fixed ratios, for protocols that call for the pulsatile pairing.
