What is MK-677 powder?

MK-677 (Ibutamoren) is a growth hormone secretagogue, which mimics the growth hormone. It also increases insulin-like growth factor 1 (IGF-1). Researchers have found MK-677 to help build muscle, reduce muscle wasting, increase bone density, and reverse aging.

Growth hormone pulse intensity can be increased through 4 possible mechanisms:

Increasing GHRH (growth hormone releasing hormone) release.
Amplifying GHRH signaling in somatotrophs of the anterior pituitary gland.
Reducing somatostatin release (somatostatin turns off GH release).
Inhibiting of somatostatin receptor signaling.Mk-677 was found to work through all 4 of these mechanisms. After ingestion, Growth Hormone (GH) was shown to increase dose dependently, at doses starting at 5 milligrams (mgs) a day.
