MedKoo product information:
Ibutamoren, also known as MK-677 (L-163,191), is a drug which acts as a potent,
orally active growth hormone secretagogue, mimicking the GH
stimulating action of the endogenous hormone ghrelin. It has been
demonstrated to increase the release of, and produces sustained
increases in plasma levels of several hormones including growth hormone
and IGF-1, but without affecting cortisol levels. It is currently
under development as a potential treatment for reduced levels of these
hormones, such as in growth hormone deficient children or elderly
adults, and human studies have shown it to increase both muscle mass and
bone mineral density, making it a promising therapy for the
treatment of frailty in the elderly. It also alters metabolism of body
fat and so may have application in the treatment of obesity. See
L 163191; MK-0677; MK-677.
