Ibutamoren (or Nutrobal) is a non-peptidic, potent, long-acting, orally-active, and selective agonist of the ghrelin receptor and a growth hormone secretagogue, mimicking the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin. The substance is an orally administrated growth hormone secretagogue originally developed by Reverse Pharmacology. Developmental code names are MK-677, MK-0677, L-163,191. A secretagogue is the term for a substance that chemically signals for the pituitary gland to secrete growth hormone. In other words, Nutrobal could be compared to peptides like GHRP-6 or Ipamorelin, only it doesn’t require any injections nor does it have any side effects like GHRP-6. This GHS (Growth Hormone Secretagogue) was developed in an aim to combat such conditions as muscle wasting, obesity and osteoporosis. It was also targeted towards treatment of elderly hip fracture patients.
