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…. GHRP-6 is a growth hormone / igf-1 axis that ghs-r1a receptor agonism ghrp-6 binds the growth hormone secretagogue receptor type 1a (ghs-r1a) - the same receptor targeted by endogenous ghrelin, ghrp-2, hexarelin, ipamorelin,…. The two differ in mechanism, half-life (~15-30 minutes vs ~20–30 minutes), and typical dose range. ### Which has the longer half-life, GHRP-2 or GHRP-6? GHRP-2 has a half-life of ~15-30 minutes. GHRP-6 has a half-life of ~20–30 minutes. Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, GHRP-2 or GHRP-6? Current lowest live price on BodyHackGuide: GHRP-2 from $29.00, GHRP-6 from $29.00. 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 GHRP-6? Stacking depends on mechanism overlap, safety profile, and goals. GHRP-2 and GHRP-6 should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds. ## See current vendor prices Live listings from the vendors we track, refreshed continuously.
