Hexarelin
Growth-hormone-releasing peptide (ghrelin-receptor agonist)
A potent synthetic GH-releasing hexapeptide, structurally related to GHRP-6, additionally studied for cardiovascular-tissue effects in preclinical models.
Mechanism under study
A strong ghrelin-receptor agonist driving GH release; research also notes interaction with CD36 receptors relevant to cardiac tissue. Frequent dosing is associated with receptor desensitization.
Research-reported dosing
Research references commonly cite ~100 mcg per dose; desensitization with sustained frequent use is a noted research consideration. Not established for human use.
5 mg vial + 2 mL bacteriostatic water = 2500 mcg/mL.
A 100 mcg dose ≈ 4 units (25 mcg per unit).
