Description
MK‑677 (Ibutamoren) is a non‑peptide, orally‑active growth hormone secretagogue designed for laboratory research. Acting as a ghrelin (GHS‑R1a) receptor agonist, it stimulates sustained release of growth hormone and insulin‑like growth factor‑1 (IGF‑1) in both humans and animal models
Clinical studies show that daily oral MK‑677 can significantly increase serum GH and IGF‑1 levels, improving nitrogen balance under caloric restriction and promoting lean body mass—though evidence of long-term growth effects remains varied
Researchers conduct studies on MK‑677 to explore:
- GH/IGF‑1 axis stimulation
- Muscle preservation and anti-catabolic effects
- Improved sleep architecture (REM and slow-wave sleep)
- Metabolic and recovery applications
Key Features:
- 25 mg oral-dose ready powder
- Non-suppressive mechanism with oral convenience
- High stability for reproducible lab results
