  Ibutamoren (also known as MK-677), promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1). A great thing about Ibutamoren is that it increases growth hormone levels with little or no increase in other hormones, like cortisol.

Our MK-677 is a high quality 99% powder measured precisely and attractively priced. Other SARMs and performance enhancers on offer in our shop are Andarine S4 and Cardarine GW-501516.


Potential Uses of Ibutamoren

 1) Building Muscle

 Ibutamoren is frequently used as an anabolic substance, to increase lean body mass. It is orally active and can be taken once a day.

In 24 obese men, a two-month treatment with ibutamoren increased lean mass, and transiently increased basal metabolic rate (BMR) [1].

  2) Bone Density

 Growth hormone increases bone turnover and eventually bone density.

In one study with 292 post-menopausal women, ibutamoren increased bone mineral density, which helps increase bone strength and prevent osteoporosis [2].

  3) Sleep

 A study showed that in both younger and elderly subjects, ibutamoren improved sleep quality and REM (rapid eye movement) sleep duration [3]. Apart from scientific studies, there have been many reports of subjective improvements in sleep quality, across various online forums.

  4) Wound Healing and Tissue Regeneration

 Growth hormone increases tissue regeneration and wound healing, so ibutamoren may help with these.

Side Effects are an increase in appetite and transient, mild lower extremity edema and muscle pain. Most studies report little or no side effects.
