Ghrelin-receptor agonism

Acting on the ghrelin / GH-secretagogue receptor to release growth hormone.

Growth-hormone-releasing peptides (GHRPs) act on the ghrelin (GH-secretagogue) receptor — a pathway distinct from GHRH. Some also influence appetite signalling. They are frequently studied alongside GHRH analogs because the two pathways can act together.

FAQ

What does ghrelin-receptor agonism do?

Growth-hormone-releasing peptides (GHRPs) act on the ghrelin (GH-secretagogue) receptor — a pathway distinct from GHRH. Some also influence appetite signalling. They are frequently studied alongside GHRH analogs because the two pathways can act together.

Which peptides act through ghrelin-receptor agonism?

Ipamorelin, Hexarelin, Ghrp 2, Ghrp 6. They share this pathway but differ in evidence, approval, and safety.

Does this mechanism prove a peptide works?

No. Mechanistic plausibility is not proof of clinical benefit — a plausible pathway is a reason to study a compound, not evidence that it works in humans.
