Pharmacological Profile & Mechanism of Action
What it is: MK-677 (also known as Ibutamoren) is an orally active, non-peptide growth hormone secretagogue that functions as a potent, long-acting ghrelin receptor agonist.
How it works: It binds to the ghrelin/GHS-R1a receptor in the brain and pituitary gland, sustained by a long biological half-life of 24 hours. A single oral dose stimulates continuous, multi-pulsatile growth hormone and IGF-1 secretion around the clock, without requiring any injections.
Why researchers study it: Studied for combating muscle wasting, improving bone mineral density, increasing deep sleep stages, accelerating tendon repair, and enhancing overall body vitality through simple oral administration.
