CJC-1295 and Ipamorelin 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 Ipamorelin is a selective growth-hormone secretagogue studied for its clean GH-release profile. 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 Ipamorelin work?
Ipamorelin is a selective growth-hormone secretagogue that mimics ghrelin at its receptor to trigger growth-hormone release. It is valued in research for a relatively "clean" profile, with less effect on appetite, cortisol, and prolactin than some older secretagogues.
CJC-1295 vs Ipamorelin: how to choose
Choosing between CJC-1295 and Ipamorelin 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 Ipamorelin leans toward Growth hormone release and Recovery. Where they overlap, the practical differences are usually in mechanism and how far the research has actually progressed. The two are also commonly discussed together as a stack rather than as either/or.

Frequently asked questions
Both are Growth Hormone peptides. CJC-1295 is a growth-hormone-releasing hormone analog studied for GH support; Ipamorelin is a selective growth-hormone secretagogue studied for its clean GH-release profile. They're most researched for Growth hormone release, Body composition (CJC-1295) and Growth hormone release, Recovery (Ipamorelin), 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.
CJC-1295 and Ipamorelin are commonly discussed together as a stack in the research and community, based on complementary mechanisms. Selpho provides no dosing or protocols — any combination should only be considered with a licensed professional.
