CJC-1295 and Tesamorelin are both Growth Hormone peptides, but they're studied for different things. In short, CJC-1295 is a growth-hormone-releasing hormone analog studied for GH support, while Tesamorelin is a GHRH analog approved for HIV-associated lipodystrophy and studied for visceral fat. This page compares the two side by side — what each is researched for, how mature the evidence is, and how they're typically used — so you can see where they overlap and where they differ. It's educational information only, not medical advice, and neither is a substitute for a conversation with a licensed professional.

How does CJC-1295 work?
CJC-1295 is a synthetic analog of growth-hormone-releasing hormone (GHRH). It stimulates the pituitary to release the body's own growth hormone in a more sustained way, and is often researched together with a ghrelin-type secretagogue for a more pulsatile release pattern.
How does Tesamorelin work?
Tesamorelin is a stabilized GHRH analog that boosts the body's growth-hormone axis. Unlike most research peptides, it is FDA-approved for a specific indication — reducing excess visceral (abdominal) fat in people with HIV-associated lipodystrophy — and has also been studied for cognitive and metabolic outcomes.
CJC-1295 vs Tesamorelin: how to choose
Choosing between CJC-1295 and Tesamorelin really comes down to your specific goal — and it's a decision for you and a licensed professional, not something to settle from a web page. CJC-1295 is most associated with Growth hormone release and Body composition, while Tesamorelin leans toward Visceral fat reduction and Metabolic health. Where they overlap, the practical differences are usually in mechanism and how far the research has actually progressed.

Frequently asked questions
Both are Growth Hormone peptides. CJC-1295 is a growth-hormone-releasing hormone analog studied for GH support; Tesamorelin is a GHRH analog approved for HIV-associated lipodystrophy and studied for visceral fat. They're most researched for Growth hormone release, Body composition (CJC-1295) and Visceral fat reduction, Metabolic health (Tesamorelin), respectively.
There's no universal "better" — it depends on your goal, and for most of these compounds robust head-to-head human evidence doesn't exist. The right choice is one made with a licensed professional. Selpho does not rank or prescribe; it offers educational information and a research-backed advisor.
They're in the same category, and combining research compounds is something to approach only with a licensed professional, since interactions and individual context matter. Selpho provides no dosing or protocols.
