MK677 Australia stock from Vi Corpus comes as GROWTH, a 25 mg/ml research solution of ibutamoren. MK-677 is a non-peptide growth hormone secretagogue that activates the ghrelin receptor, so it is widely used in studies of GH pulses, IGF-1 and body composition.
Key research features of MK-677
- Ghrelin receptor agonist. It mimics ghrelin at GHS-R1a, which triggers pituitary growth hormone release.
- Orally active molecule. Unlike peptide secretagogues, it is a small molecule with good oral bioavailability in animal models.
- Long activity window. Human studies reported a half-life of around a day, with raised IGF-1 over long periods.
- Not a true SARM. It is often sold with SARMs but works on a completely different receptor.
- Third-party tested. Batch reports are available through our Lab Tests page.

Research applications
Merck developed ibutamoren in the 1990s, and clinical studies examined it in older adults, in diet-induced muscle loss and in GH-deficient children. For example, one two-year trial measured raised GH and IGF-1 levels alongside changes in lean mass. Researchers also study its effect on sleep architecture and appetite, because ghrelin signalling influences both. In addition, it is often compared with injectable peptides such as Ipamorelin.

Frequently asked questions
Is MK-677 the same as somatropin?
No. Somatropin is growth hormone itself, whereas MK-677 stimulates the body to release its own GH.
Is MK-677 a SARM?
No. It is a growth hormone secretagogue, although it is usually listed with SARMs.
Is MK-677 approved in Australia?
No. It is not TGA-approved, so we sell it for laboratory research use only.
