MK-677 (Ibutamoren) is an orally active, non-peptide growth hormone secretagogue. It mimics the action of ghrelin by binding to ghrelin receptors in the brain, which signals the pituitary gland to increase endogenous growth hormone (GH) and insulin-like growth factor 1 (IGF-1) secretion without altering cortisol levels.

What It Is Commonly Used For

• IGF-1 & Growth Hormone Research: Studied for its ability to sustain elevated serum levels of GH and IGF-1 in research models over prolonged evaluation periods.

• Lean Tissue Preservation: Evaluated in metabolic studies for supporting nitrogen retention and maintaining lean body mass during caloric deficits.

• Sleep Quality & Recovery: Researched for its influence on deep REM sleep architecture and biological cellular repair processes.

General Purpose

To provide a non-hormonal, orally bioavailable compound for investigating natural growth hormone elevation, metabolic regulation, and recovery pathways in laboratory research.
