MK-677 (Ibutamoren)

The Oral GH Booster

MK-677 is an orally active growth hormone secretagogue that mimics ghrelin to stimulate GH and IGF-1 release. While not technically a peptide, it is universally researched and discussed alongside peptides. It promotes sustained GH elevation without suppressing natural production, making it popular for muscle growth, deep sleep enhancement, and anti-aging protocols.

If You Take This

  • Increases growth hormone and IGF-1 levels
  • Dramatically improves deep sleep quality
  • Promotes lean muscle mass gains
  • Enhances bone mineral density
  • Boosts appetite (beneficial for bulking)
  • Supports skin elasticity and hair health

Protocol

Dosing
10-25mg oral daily. Start at 10mg for 2 weeks to assess tolerance, then increase to 15-25mg. Take at night to maximize sleep-related GH pulse.
Cycle Length
8-12 weeks on, 4 weeks off. Some users run extended cycles of 3-6 months at lower doses (10-15mg) under monitoring.
Half-Life
24 hours (oral, once-daily dosing)
Best Time
Before bed (maximizes sleep GH pulse) or morning if appetite increase is desired
