TWP Nutrition MK-677 (Ibutamoren) promotes muscle mass by the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1). The TWP Nutrition MK677 is the growth hormone secretagogue. Ibutamoren increases levels, by mimicking the action of the hormone ghrelin, and binding to one of the ghrelin receptors. Activated ghrelin receptors stimulates growth hormone release.
Benefits of increased GH and IGF-1 include:
- Increased muscle mass
- Increased bone turnover and eventually bone density
- Reduced fat
- Improved sleep quality and REM (rapid eye movement) sleep duration.
- Reduced muscle wasting
- 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.
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.
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.
