Which should you choose? Here's what you need to know.
Hexarelin is the most potent GHRP for raw GH release but desensitizes faster and raises cortisol and prolactin more. GHRP-2 is nearly as strong with a better long-term profile.
GHRP-2 is considered one of the strongest growth hormone releasing peptides. It produces a robust GH pulse with only moderate increases in cortisol, prolactin, and appetite. It's often chosen as a middle ground — more potent than ipamorelin, with fewer side effects than hexarelin.
Choose GHRP-2 if:
You want strong GH release you can sustain over longer cycles without significant desensitization or hormonal side effects.
Hexarelin is the most potent of the classic GHRPs in terms of raw GH release. However, it also raises cortisol and prolactin more than GHRP-2, and studies show it desensitizes noticeably after about 4 weeks of continuous use — meaning the GH response drops over time.
Choose Hexarelin if:
You want the most powerful short-term GH spike and plan to cycle it with breaks to manage desensitization.
