Hexarelin has no approved label, so every figure here traces back to published human pharmacology studies rather than a prescribing guideline. Those studies gave it intravenously at about 1 to 2 mcg/kg and subcutaneously at similar mcg/kg doses, which works out to roughly 100 mcg for many adults.[1][2][3]
Reviewed for accuracy · Last reviewed July 8, 2026Doses below describe what human studies used, not a recommendation. Hexarelin is investigational and has no approved dose:
A dose-response study found a half-maximal GH response near 0.48 mcg/kg IV, with the curve plateauing at higher doses. Treat these numbers as a description of what was studied, not a recommendation.
A documented caveat for GHRPs is that the GH-releasing effect partially desensitizes with continued use, more so with continuous than intermittent dosing. Reviews note this attenuation without endorsing any specific cycling schedule.
