MK-677
Ibutamoren - oral ghrelin receptor agonist · Growth Factor Research
Orally active growth-hormone secretagogue, supplied as capsules.
MK-677 (ibutamoren) is a non-peptide, orally bioavailable growth-hormone secretagogue that mimics ghrelin at the GHS-R1a receptor. It is studied as an oral alternative to injectable secretagogues in GH-axis research. Supplied as capsules. Research use only.
Available sizes: 12.5mg · Form: Capsules (12.5 mg x 60)
Every lot ships with an independent third-party Certificate of Analysis - see the linked report for measured values.
How it is studied
- Ghrelin receptor agonism (Secretagogue) - Acts at GHS-R1a, the same receptor engaged by endogenous ghrelin.
- GH and IGF-1 axis (Endocrine) - Studied for pulsatile growth-hormone release and downstream IGF-1 elevation.
- Oral bioavailability (Pharmacology) - Non-peptide structure survives first-pass metabolism, unlike injectable secretagogues.
Research Use Only. Not for human or veterinary use.
