What is MK-677 12.5MG (60 capsules)?
Chemical Structure of MK-677 12.5MG (60 capsules)
MK‑677 is a small-molecule growth hormone secretagogue with a spiro-aminoamide backbone, rather than a peptide structure. It has the chemical formula C₂₇H₃₆N₄O₅S and a molecular weight of approximately 528.7 Da. PubChem lists the compound under CID 9939050 (free base) and CID 178024 (mesylate salt), with synonyms including MK‑677, MK‑0677, Oratrope, and L‑163,191.
What Are the Effects of MK-677 12.5MG (60 capsules)?
Research studies indicate that MK‑677:
- Stimulates GH and IGF‑1 Secretion: Maintains elevated IGF‑1 levels for over 24 hours in animal and human research models, confirming its activity on the GH axis.
- Promotes Lean Mass and Nitrogen Balance: In calorie-restriction studies, MK‑677 improved nitrogen retention and increased fat-free mass without affecting cortisol.
- Supports Bone Metabolism: Demonstrated ability to elevate bone turnover markers and bone mineral density in preclinical models.
- Improves Sleep Architecture: Shown to increase REM and slow-wave sleep in laboratory trials.
- Enhances Muscle and Metabolic Research Outcomes: Used in studies on muscle recovery and metabolic health, reinforcing its value in experimental protocols.
