OLIMP ACETOSTERON is a combined product in which the synergism of combined ingredients with toning properties and facilitating the development of muscle mass and strength through the influence on the synthesis, activity, and metabolism of endogenous testosterone has been used. Steroid saponins of Tribulus terrestris (diosgenin, ruscogenin, gitogenin and tigogenin) display structural similarity to human steroid hormones, act on their metabolism and affect the level of endogenous testosterone. Acetyl-carnitine (ALC) provides acetyl groups for condensation of acetates – an important stage in testosterone synthesis. Zinc and magnesium control the activity of dehydrogenase, the key enzyme in testosterone synthesis. Zinc, as an ingredient of steroid receptors (so-called “zinc fingers”), determines the response of muscle tissue to the anabolic effect of testosterone action. Magnesium, as a stabiliser of acetyl groups, catalyses condensation of acetates and stimulates the production of endogenous testosterone. Vitamin B6, a coenzyme of a number of enzymes catalysing transformations of amino acids, facilitates the absorption of chelates from the gastrointestinal tract and the release of elements from chelates after their penetration into tissues. OLIMP ACETOSTERON is designed for high-performance athletes and for persons practicing recreational sports, aiming at the rapid development of muscle mass and strength Caution: the product is intended only for adults.
