Tesamorelin vs CJC-1295
An FDA-approved GHRH analog that selectively trims visceral fat. 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 Tesamorelin and CJC-1295?
- Tesamorelin is an engineered analog based on Growth-hormone-releasing hormone; CJC-1295 is an engineered analog based on Growth-hormone-releasing hormone. Tesamorelin 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 Tesamorelin and CJC-1295 compare?
- The reported circulating half-life of Tesamorelin is ~26-38 min (subcutaneous); 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.
- Is Tesamorelin the same as Egrifta?
- Egrifta is a brand name of Tesamorelin. This comparison describes the molecules, not branded products.
