Ibutamoren (developmental code names MK-677, MK-0677, L-163,191) is a potent, long-acting, orally-active, selective, and non-peptide agonist of the ghrelin receptor and a growth hormone secretagogue, mimicking the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin. 

It has been shown to increase the secretion of several hormones including GH and insulin-like growth factor 1 (IGF-1) and produces sustained increases in the plasma levels of these hormones without affecting cortisol levels. Ibutamoren can help increase muscle growth, burn fat and improve recovery. Those who use SARMs and SARM-like compounds commonly follow 8 week cycles for lean muscle gain and strength enhancement then take the following 8 weeks off. Ibutamoren works well at lower doses.

A peptide is a short sequence of chained amino acids. Amino acids in a peptide are linked to one another in a sequence called a peptide bond. Proteins are distinguished from peptides by the amount of aminos in a chain. Peptide chains are much shorter than proteins. Two or more amino acids are typically regarded as a peptide bond. Proteins are long molecules made up of peptide chains that contain fifty or more bonds of aminos. Enzymes within the body break down and digest protein into peptides. These peptides are then utilised throughout the body to serve a multitude of functions. For example, some peptides are adapted to deliver hormones around the bodily system.

Cells require proteins and peptides to serve their individual functions. Proteins serve to structure cells, tissue and organs, whereas peptides dictate and regulate the activities of different cell types.
