GHRP-2 is a growth hormone / igf-1 axis that ghs-r1a receptor agonism ghrp-2 binds the growth hormone secretagogue receptor type 1a (ghs-r1a), the endogenous target of ghrelin, with nanomolar affinity. ghs-r1a is expressed…. Ipamorelin is a growth hormone / igf-1 axis that ipamorelin acts as a selective agonist at the growth hormone secretagogue receptor 1a (ghs-r1a), the same receptor activated by endogenous ghrelin - the "hunger hormone" secreted…. The two differ in mechanism, half-life (~15-30 minutes vs ~2 hours (plasma)), and typical dose range. ### Which has the longer half-life, GHRP-2 or Ipamorelin? GHRP-2 has a half-life of ~15-30 minutes. Ipamorelin has a half-life of ~2 hours (plasma). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, GHRP-2 or Ipamorelin? Current lowest live price on BodyHackGuide: GHRP-2 from $29.00, Ipamorelin from $24.99. Prices are pulled from the vendor listings tracked on BHG and change frequently — see the compare tables on each compound page for the current set of offers. ### Can you stack GHRP-2 and Ipamorelin? Stacking depends on mechanism overlap, safety profile, and goals. GHRP-2 and Ipamorelin should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
