What is Ibutamoren?
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.
Key Benefits & Mechanisms
raises GH/IGF-1
increases appetite
supports lean mass retention
oral non-peptide secretagogue
Research Summary
Clinical studies show oral ibutamoren reliably elevates GH and IGF-1 over 24 hours with once-daily dosing. Body composition and appetite effects vary by population, and development has been limited by metabolic side effects.

Anamorelin
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.
