CJC-1295 vs Growth-hormone-releasing hormone

A long-acting GHRH analog engineered to stretch GH pulses. The hypothalamic signal that tells the pituitary to release GH. Side by side: type, evidence tier, receptor, molecular weight, and half-life — the same fields as each monograph, rearranged so the engineering difference is visible.

Common questions

What is the difference between CJC-1295 and Growth-hormone-releasing hormone?
CJC-1295 is an engineered analog based on Growth-hormone-releasing hormone; Growth-hormone-releasing hormone is an endogenous hormone. CJC-1295 signals at GHRH receptor (GHRHR), a class B GPCR; Growth-hormone-releasing hormone signals at GHRH receptor (GHRHR), a class B GPCR.
How do the half-lives of CJC-1295 and GHRH compare?
The reported circulating half-life of CJC-1295 is ~6-8 days (DAC form); ~30 min without DAC; Growth-hormone-releasing hormone is ~7–50 min. These are reference values for the native or representative form — educational only, not dosing advice.
