What it is

Hexarelin is a six-amino-acid growth hormone secretagogue, structurally related to GHRP-6 and producing a stronger response. It has been studied in humans for GH release and in cardiac research, and it is not approved. It is the strongest GH-releasing peptide in common circulation, with a specific limitation the others do not share.
