MASS+ Rx 60 caps


Core Labs MASS + RX is one of the extremely strong anabolic agents that affect the significant development of strength and muscle mass in a relatively short time. Contains two strong ingredients building new Dymethazine muscle tissue: 2,17-dimethyl-5-androstane-17-ol-3,3′-azine and Mentabolon 7-alpha-methyl-estra-4-ene-3,17-dione enriched a powerful NAC antioxidant and vitamin E. A supplement rich in ingredients that increase lean muscle mass, increase training endurance and increase fat loss. MASS + RX provides the effect of full, hard muscles, maximally sculpting the figure. The preparation with anti-progesterone effect, reduces the negative effect of estrogen, affecting increased libido.

When using Mass + RX, we recommend consuming an increased amount of protein than normal, because during a cycle on prohormones it is much more digestible and is used for muscle building material. It is also important to provide the right amount of energy resources such as carbohydrates and fats, because the muscle building process requires a lot of energy. After using the product, it is extremely important to use Post Cycle Therapy products, e.g. PCT Rx, which will restore your body’s natural hormonal balance.

NAC – by inactivating reactive oxygen species and reducing oxidative stress, it protects cells from damage and supports the body’s immunity. Increases endurance in athletes, improving their performance and susceptibility to fatigue. Facilitates expectoration, lung ventilation, gas exchange and oxygenation. It also accelerates post-workout regeneration processes and reduces inflammation caused by overload. As a compound supplying acetyl groups, it supports testosterone production. Due to the strong stimulation of regeneration of damaged liver cells (hepatocytes), it is used by some groups of athletes during and after the cycle using pro-hormones and steroids.

2,17-dimethyl-5-androstane-17-ol-3,3′-azine – a compound twice as strong as anabolic in terms of testosterone, ensuring rapid growth of muscle mass up to 10 kg in 6 weeks. Increases strength, allowing you to train with a greater load, sculpting the figure. It is an ideal ingredient for anyone who fights for each subsequent kilogram of pure muscle mass and every kilogram of strength more while maintaining clean mass and phenomenal sculpture.

7-alpha-methyl-estra-4-ene-3,17-dione – this compound is a derivative of nandrolone, and the effects are similar to the injectable form of trestolone acetate. It is a strongly anabolic, moderately androgenic compound that causes significant strength gains and increases in lean muscle mass. A huge increase in energy and training aggression should be noticed quite quickly. Mentabolan can be used in cycles during both building muscle mass and reducing body fat.

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