Are the MK-677 capsules an oral growth hormone?

MK-677 (Ibutamoren) capsules are not a growth hormone themselves, but they are often referred to as an oral growth hormone secretagogue. This means they stimulate the body to naturally increase the natural release of growth hormone and IGF-1 (Insulin-like Growth Factor 1). Research has found that MK-677 use impacts body composition, causing lean muscle mass growth. Unlike direct growth hormone injections, MK-677 works by mimicking the action of ghrelin, a hormone that stimulates hunger, and binding to ghrelin receptors, which stimulates the pituitary gland to release growth hormone.

What is the recommended dose for MK-677 Ibutamoren?

Peptide Works supplies research compounds for research use only and are not classed as a dietary supplement. MK677 capsules are supplied in 10mg capsules. Furthermore, each peptide capsule contains a set 10mg dosage of MK-677, reducing the risk of inaccurate dosing. View the full range of Peptide Capsules available for research use from Peptide Works.

About this compound

MK-677 Capsules are a laboratory research material containing ibutamoren, a synthetic, non-peptide small-molecule growth hormone secretagogue. Published research has investigated ibutamoren across growth hormone research, endocrine research, ghrelin receptor pharmacology, growth hormone secretagogue activity, GH–IGF-1 axis research, metabolic research, body composition research, bone metabolism, bone turnover, and growth hormone signaling. Research has also examined IGF-related biomarkers, growth hormone isoforms, and endocrine regulation in experimental research.
