UK SARMs GH Pep (MK-677) is an orally administrated GH secretagogue. A secretagogue is the term for a substance that naturally signals the pituitary gland to secrete GH. In other words, UK SARMs GH Pep could be compared to peptides like IGF-1 Lr3 or MGF(peptides), only it doesn’t require any injections nor does it have any side effects.

It has been demonstrated to increase the release of and produces sustained increases in plasma levels of several hormones including GH and insulin-like-growth-factor 1 (IGF-1) for up to 24 hours.

The product was originally developed in a laboratory, to help patients increase muscle mass and bone mineral density. Research has also suggested that MK-677 can alter your metabolism of body fat, whilst also helping to improve the subjects’ sleep.
