YK-11 PRO 10mg 60 caps


YK-11 Core Labs formulation based on SARM (17α, 20E) -17.20 – [(1-methoxyethylidene) bis (oxy)] – 3-oxo-19-norpregna-4,20-diene-21-carboxylic acid Methyl ester, a compound that selectively activates androgen receptors. The preparation naturally increases the level of follicles, which affects the body’s ability to create new muscle cells. Folistatin also has the ability to block the activity of myostatin, which allows for unrestricted muscle growth. YK11 binding to androgen receptors affects the growth of bone strength, preventing excessive brittleness. Increased amount of protein B kinase in the cells, during the use of the product promotes the growth of bone cells (osteoblasts, osteocytes and osteoclasts). The addition of vitamin E influences the increase in bioavailability of the active substance. N-acetyl-1-cysteine ​​supports the proper functioning of the liver and increases the level of glutathione – one of the strongest antioxidants.

YK-11- 17-alpha, 20E) 17.20 – [(1-methoxyethylidene) bis (oxy)], 19-dien-4,20-norpregna 3-oxo ester 21-carboxylic acid is the latest generation chemical compound, having all SARM properties. YK-11 binds to the androgen receptor, but does not lead to classic side effects attributed to the group of androgens, such as enlarged cortical gland, excessive hair growth or increased aggression. In a study conducted two years later, a drastic reduction in the risk of side effects was confirmed, which is attributed to the entire SARM group, however, YK 11 showed a greater anabolic effect than the identical amount of DHT nanomoles, this means that this agent causes a greater increase in lean muscle mass.

NAC- is a modified form of cysteine ​​that has been attached to the acetyl group. has the effect of raising the level of antioxidant-glutathione, which in turn causes a reduction of damage at the cellular level, accelerates post-traumatic regeneration processes and promotes the formation of dry muscle mass. The reduction of damage at the cellular level is closely correlated with the delay of aging processes. NAC binds and excretes toxic metabolites from the body when steroids pass through the liver.

Vitamin E (TPGS) – a water-soluble derivative of natural vitamin E, an innovation in the field of substance absorption. Vitamin E TPGS is a nonionic surfactant used as an absorption enhancer and antioxidant. Vitamin E TPGS is also used as an effective source of natural vitamin E for both therapeutic and nutritional purposes.
