We are one of the renowned manufacturers, traders, and exporters of Ibutamoren powder. This powder is a potent and long acting drug that may improve strength, bone density, cognitive ability, longevity, and metabolism. It is categorized as a growth hormone secretagogue as well as selective agonist of the ghrelin receptor. This non-peptidic drug binds to the ghrelin receptor and mimics its effects. Ibutamoren powder is administered orally and promotes the nocturnal pulses of growth hormone.


  • Protection of the heart

  • Increased appetite and muscle mass

  • Modulation of glucose and energy homeostasis

The development codes of Ibutamoren (INN) are L-163,191, MK-677 and MK-0677. This compound is widely known as a non-peptidic, orally active, potent and long-acting agonist of the ghrelin receptor. It also works as a growth hormone by mimicking its action and can be used for increasing the level of plasma in various hormones such as insulin without having any affect on the level of cortisol.

MK677 is capable of increasing body mass without changing the visceral fat ( also called as total fat mass). Moreover, it helps in sustaining the activation of GH-IGF-1 axis. It has also been observation for minimizing the level of aforementioned hormones in elderly adults and children that possess deficiency of growth hormones.
