What is MK-677?
Ibutamoren (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. 
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.
How does Ibutamoren work?
Ibutamoren MK-677 is a nonpeptide spiropiperidine and it is functionally indistinguishable in vitro as well as in vivo from the GHRP-6. However, ibutamoren stimulates GH release via a pituitary and hypothalamic receptors (not the same as the GH-delivering hormone receptors), and has the capacity to sustain GH plasma levels and IGF1 release without having affected endogenous cortisol.
Growth hormones pulse intensity could be elevated through 4 possible ways:
Growing GHRH release (growth hormones releasing hormone).
Increasing GHRH signaling in somatotrophs from the anterior anterior pituitary gland.
Reducing somatostatin release (somatostatin turns off GH release).
Suppressing somatostatin receptor signaling.
Ibutamoren MK-677 was shown to function through all of these four mechanisms. After ingestion, Growth Hormones (GH) was proven to improve dose dependently, at doses beginning at 5 mg (mgs) each day.
Dosages range from 10-40 mg per day. The most commonly used is 20-30 mg.
Clinical trials have demonstrated the efficacy of 25 mg to increase IGF-1. We take the supplement in one portion once a day, because of the 24-hour half-life.

In a study on it's effects on catabolic states, a once daily oral dose of 25mgs was given to healthy young men subjected to short-term diet-induced nitrogen wasting. After 7 days of this dose, the subjects showed a sustained increase in serum concentration of IGF-1 and Growth Hormone; in addition, the nitrogen wasting was reversed, showing great potential for treatment of conditions involving muscle wasting.
A study done for the treatment of osteoporosis and bone mineral density showed some increase in bone density, so there is a true impact on bone mineral density. This can help with injury recovery during your cycle.
