in SARMs
MK 677, or as it’s more commonly known, Ibutamoren is a SARM that was designed by Reverse Pharmacology. It’s an orally administered SARM whose main purpose is to work as a growth hormone. It’s also a secretagogue (a substance that stimulates the production of another substance) and it’s designed to cause the pituitary gland to work even harder and release the growth hormone.
