What it is
A synthetic hexapeptide growth hormone secretagogue, structurally related to GHRP-6.
How it works
Agonist of the ghrelin/growth hormone secretagogue receptor (GHS-R1a), stimulating pituitary GH release; also acts at cardiac CD36 receptors in preclinical studies.
Where it's used
Studied in research as a potent growth hormone secretagogue.
Regulatory status
Not FDA-approved; research compound.
Reconstitution
Supplied as a lyophilized powder requiring reconstitution with bacteriostatic water prior to use.
Tracking it
Hexarelin is injectable, so two things matter in a log: when you dosed and where. Rotating sites and writing both down prevents the classic “did I already pin the left side?” problem. with a half-life of about 48 minutes, a dose log also lets a tracker model the relative amount still in your system between doses.
