Products of this group are based on the compound called MK-677, commonly referred to as ibutamoren. Its main property is imitating the activity of ghrelin, and consequently, increasing the concentrations of growth hormone (GH) and insulin-like growth factor (IGF-1). Another advantage of ibutamoren is that unlike ghrelin, which increases the level of cortisol, that is a stress hormone with catabolic properties, it helps to reduce cortisol concentration. Preparations containing MK-677 are safe, as they have been clinically tested multiple times and proven to exert no negative effects on the human organism.
Their anticatabolic and anabolic properties make preparations containing MK-677 versatile agents recommended for the period of perfecting muscle definition, developing muscle mass, as well as for regeneration periods. Ibutamoren can be used independently or serve as an aid in various training cycles and stages. Because it is administered orally, its supplementation is safe and easy.
