Hexarelin and Ipamorelin are both Growth Hormone peptides, but they're studied for different things. In short, Hexarelin is a potent GH secretagogue also studied for cardiac tissue effects, 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 Hexarelin work?
Hexarelin is a potent growth-hormone-releasing peptide. Beyond stimulating GH, research has examined direct effects on cardiac tissue through the CD36 and ghrelin receptors, making it of interest in cardiovascular studies.
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.
Hexarelin vs Ipamorelin: how to choose
Choosing between Hexarelin 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. Hexarelin is most associated with Growth hormone release and Cardiac tissue studies, 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.

Frequently asked questions
Both are Growth Hormone peptides. Hexarelin is a potent GH secretagogue also studied for cardiac tissue effects; Ipamorelin is a selective growth-hormone secretagogue studied for its clean GH-release profile. They're most researched for Growth hormone release, Cardiac tissue studies (Hexarelin) 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.
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.
