Benefit categories

Growth Hormone

Ibutamoren's defining research application — the only compound in this category taken orally rather than injected.

IGF-1 elevation

Provides sustained, 24-hour IGF-1 elevation, unlike the short pulses produced by injectable secretagogues.

Appetite stimulation

Reliably increases appetite through the same ghrelin receptor pathway used by injectable growth hormone secretagogues like GHRP-2.
