MK677 is the latest product from TWP Nutrition, the growth hormone secretagogue. Ibutamoren also known as ibutamoren mesylate or MK-677, promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1).

Ibutamoren increases levels, by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors in the brain. Activated ghrelin receptors stimulates growth hormone release from the brain.

Benefits of increased GH and IGF-1 include:
  • Increased bone turnover and eventually bone density
  • Improved sleep quality and REM (rapid eye movement) sleep duration.
  • Reduced muscle wasting
  • Increased muscle mass
  • Reduced fat
  • Possible healing of tendons, joints and ligaments

Also included in the product is;


Alpha-GPC is a cholinergic compound that is used for its cognitive-promoting properties, and to enhance power output in athletes. It appears to also support cellular membranes, and may aid in preventing cognitive decline.

Oral supplementation of alpha-GPC is of interest for nootropic purposes, as it appears to have cognitive-enhancing properties.

Athletes are at times interested in alpha-GPC due to its ability to enhance growth hormone production and to also enhance power output.

And also;


Huperzine-A is a cognitive enhancer that inhibits an enzyme that degrades the learning neurotransmitter, acetylcholine; and so due to this, a relative increase occurs.

Acetylcholine is known as the learning neurotransmitter, and is involved in muscle contraction as well. Increasing levels of acetylcholine is routinely used as a technique amongst weight-lifters and those undertaking extensive studying (college and university students).
