Mechanism of Action

Ipamorelin is a growth hormone releasing peptide that acts through ghrelin/GHS receptor signaling to stimulate growth hormone secretion. Its clinical relevance is mostly exposure and GH-response modeling, so ProtoComp treats it as a GH-axis signal with limited direct outcome evidence.
