MK-677
Catalog no. PH-MK677-001Size 10mgMW (reference) 528.7 Da
Description
MK-677 (Ibutamoren) is an orally active growth hormone secretagogue that mimics ghrelin signaling. This non-peptide compound stimulates sustained GH and IGF-1 elevation.
Mechanism of Action
MK-677 acts as a ghrelin mimetic, activating GHS-R1a receptors to stimulate GH release. Studies demonstrate reversal of diet-induced catabolism (Murphy et al., 1998) and effects on body composition (Falk et al., 2022).
Research Applications
- GH secretagogue studies (Murphy et al., 1998)
- Body composition research (Falk et al., 2022)
- Anti-catabolic effects
- IGF-1 elevation studies
