CJC-1295 vs Sermorelin
A long-acting GHRH analog engineered to stretch GH pulses. The GHRH(1-29) fragment once approved to assess and treat GH deficiency. 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.
