Sermorelin vs CJC-1295

The GHRH(1-29) fragment once approved to assess and treat GH deficiency. A long-acting GHRH analog engineered to stretch GH pulses. 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 Sermorelin and CJC-1295?
Sermorelin is an engineered analog based on Growth-hormone-releasing hormone; CJC-1295 is an engineered analog based on Growth-hormone-releasing hormone. Sermorelin signals at GHRH receptor (GHRHR), a class B GPCR; CJC-1295 signals at GHRH receptor (GHRHR), a class B GPCR.
How do the half-lives of Sermorelin and CJC-1295 compare?
The reported circulating half-life of Sermorelin is ~11-12 min; CJC-1295 is ~6-8 days (DAC form); ~30 min without DAC. These are reference values for the native or representative form — educational only, not dosing advice.
