MK-677 (Ibutamoren) is a research liquid that is a growth hormone secretagogue. It elevates growth hormone and IGF-1 levels in dogs after oral administration.

However, this stimulatory effect appears to depend on the presence of an intact pituitary.

Buy MK-677 (Ibutamoren) from Loti Labs, your trusted source for research liquids. It is sold in liquid form in 25mg per ml vials for research purposes only and not for human consumption.


MK-677 (Ibutamoren) is a non-peptide agonist of the ghrelin receptor that is potent, long-acting, and orally active. 

Research in animals shows it acts like the endogenous hormone ghrelin increasing the secretion of several hormones, including Growth Hormone and insulin-like growth factor 1 (IGF-1). It increases the plasma levels of these hormones without affecting cortisol levels, a very beneficial effect.

MK-677 (Ibutamoren) also reverses diet-induced nitrogen wasting and increases muscle mass, as seen in catabolic animals because of acute or chronic diseases.


MK-677 (Ibutamoren) acts like the ghrelin hormone released in the walls of the stomach during hunger. Ghrelin binds itself to the growth hormone secretagogue-receptor type 1a (GHS-R1a), which increases appetite. 

This whole mechanism affects the pituitary and hypothalamus, which play a role in enhancing growth, and burns the fat associated with the thighs, waist, and abdomen in research animals.

MK-677 (Ibutamoren) is active after oral administration in animals with a half-life of more than twenty (20) hours (almost 24 hours).


Based on available research, the benefits of MK-677 (Ibutamoren) may include

  • Enhancing lean muscle
  • Fat burning
  • Reducing bone injuries
