Ibutamoren MK-677

Meaning

Ibutamoren, chemically known as MK-677, is a non-peptide, potent, long-acting, orally active secretagogue that stimulates the release of growth hormone (GH). It functions by mimicking the action of the endogenous hormone ghrelin, binding to the ghrelin receptor (GHSR) in the brain. Clinically, it has been studied for its potential to increase fat-free mass, improve bone mineral density, and alter lipid profiles, primarily through the resultant increase in both GH and Insulin-like Growth Factor 1 (IGF-1) levels. It is not a SARM but is often discussed within that pharmacological context.
