Ibutamoren (also known as MK-677 and Oratrope) is an oral Growth Hormone Secretagogue and an agonist of the Ghrelin Receptor. It was developed by Reverse Pharmacology for the treatment of growth hormone deficiency, muscle wasting conditions and osteoporosis.
This is an extremely popular compound used as a replacement for regular HGH injections. It is not as powerful as elevated doses of HGH, but it is way cheaper, rarely faked and orally bioavailable. It also has some properties that make it a very interesting, unique and versatile drug.
