MK-677 (Ibutamoren)

Growth Hormone & Recovery Research

MK-677 (Ibutamoren) is an orally active growth hormone secretagogue studied for its ability to stimulate the body’s natural release of growth hormone (GH) and Insulin-like Growth Factor-1 (IGF-1) by activating the ghrelin receptor. Researchers have explored its potential to support lean muscle mass, recovery, sleep quality, bone health, and healthy aging.

Key Research Areas

  • Supports natural growth hormone and IGF-1 production
  • Promotes lean muscle development and recovery
  • Encourages deeper, more restorative sleep
  • Supports bone health and tissue repair
  • Studied for body composition, performance, and healthy aging

For Research Use Only. Not for human consumption.
