Overview
MK-677 (Ibutamoren) is a ghrelin receptor (GHSR-1a) agonist that promotes the natural release of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). Studied for its impact on recovery, body composition, and sleep quality, MK-677 supports long-term research into GH/IGF-1 pathway regulation and metabolic health.
Mechanism & Research Focus
GH & IGF-1 Stimulation: Sustained, natural hormone elevation via ghrelin receptor activation.
Metabolic Support: Evaluated for effects on lean-mass gain, fat-loss modulation, and nutrient partitioning.
Sleep & Recovery: May enhance REM sleep and nighttime GH pulsatility in research models.
Durable Activity: Orally active, long half-life compound allowing once-daily use in studies.
