What is GHRP-1?
GHRP-1 is an early synthetic growth hormone secretagogue designed to mimic ghrelin-like signaling at the GHSR-1a receptor. It is used mainly as a reference compound in endocrine and receptor-activation research.
Key Benefits & Mechanisms
growth hormone pulse support
research tool for GHSR-1a signaling
recovery and anabolic-endpoint studies
Research Summary
Preclinical and early translational work showed dose-dependent GH release and helped establish the first generation of ghrelin-mimetic secretagogues. It is far less common today than newer analogs.

Ibutamoren
Ibutamoren mesylate (MK-677)
Ibutamoren is an orally active ghrelin receptor agonist that increases pulsatile growth hormone and IGF-1 secretion. It has been studied for effects on lean mass, recovery, and age-related anabolic support.
Growth HormoneAnamorelin
Anamorelin hydrochloride (ONO-7643)
Anamorelin is a selective ghrelin receptor agonist developed to stimulate appetite and growth hormone signaling. It has been investigated primarily in cancer cachexia and other wasting states.
Growth HormoneMacimorelin
Macimorelin acetate (AEZS-130)
Macimorelin is an orally active ghrelin mimetic used as a growth hormone stimulation agent. It produces a rapid GH rise after a single dose and is used clinically to help diagnose adult GH deficiency.
Growth HormoneCapromorelin
Capromorelin hydrochloride
Capromorelin is a ghrelin receptor agonist that stimulates growth hormone release and increases appetite. It is best known in veterinary medicine, but it has also been explored in human research settings.
