What It Is

Ibutamoren (MK-677) is an oral compound that mimics ghrelin, stimulating growth hormone release. It's unique because it's taken as a capsule, not an injection.

How It Works

By activating the ghrelin receptor, it signals the pituitary to release GH. Unlike injectable peptides, its effects last 24 hours per dose, maintaining elevated GH and IGF-1.

Who It's For

Those who prefer oral dosing over injections. People looking for sustained GH elevation for muscle growth, recovery, and sleep improvement.

Who Should Avoid It

May increase appetite significantly. Monitor blood sugar. Not for diabetics without careful management. Avoid with active cancer.
