Nutrobal (Mk-677) is an orally administrated growth hormone secretagogue originally developed by Reverse Pharmacology. 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, so there are a myriad of studies done on safety.
