Nutrabol also known as MK-677, is an selective agonist of the ghrelin receptor in the body and a growth hormone secretagogue which helps stimulates the growth hormone. It is currently under development as a potential treatment in individuals with reduced levels of growth hormone (Growth hormone deficiency), and frailty in elderly. Human studies has shown Nutrabol to sustain activation of GH-IGF-1, Which lead to an increase in lean body mass and bone mineral density.
Nutrabol helps promote the secretion of the growth hormone (GH) and increases insulin like growth factor 1(IGF1). It can increase the growth hormone by selectively mimicking the hormone Ghrelin. It binds to one of the ghrelin receptors GHSR in the brain. When GHSR is activated it releases spikes of growth hormone in the body.
GHSR controls your appetite, biological rhythms, and the general feelings of pleasure and mood. Most who take Nutrabol report an increase in appetite.
