Ibutamoren (MK-677)

🧬 Clinical Overview

What it is:

Ibutamoren (also known as MK-677) is an orally administered growth hormone secretagogue designed to stimulate the body’s natural production of growth hormone and IGF-1. Unlike injectable peptides, Ibutamoren is taken as a once-daily capsule and works by mimicking ghrelin at the receptor level, signaling the pituitary to increase endogenous hormone release.

This program is intended for patients seeking support with recovery, sleep quality, body composition, and overall metabolic resilience under clinician guidance.

⚙️ How It Works

Ibutamoren binds to the ghrelin receptor (GHS-R1a), which signals the body to increase pulsatile growth hormone secretion without suppressing natural production. This leads to downstream increases in IGF-1 while maintaining normal pituitary function.
