Testosterone is an endogenous hormone necessary for the normal development of male genital organs and secondary sexual characteristics, to maintain normal function of the testicles, the prostate gland and seminal vesicles, maintaining libido and potency. The use of the drug for the treatment of hypogonadism in men leads to a clinically significant increase in the concentration in the plasma of testosterone, dihydrotestosterone and androstenedione and a decrease in globulin binding sex hormones (SHGG). In men with primary (hypergonadotropic) hypogonadism, the use of the drug leads to normalization of gonadotropin concentration.
After ingestion, a large part of the testosterone undecanoate together with the lipophilic solvent is absorbed into the small intestine and enters the lymphatic system, thus avoiding the primary passage through the liver. With the absorption of Testosterone Undecanoate kaufen is partially reduced with the formation of dihydrotestosterone undecanoate. From the lymphatic system, he enters the plasma. In the plasma and tissues, as a result of the hydrolysis of testosterone undecanoate and ditrotestosterone undecanoate, the natural male sex hormones testosterone and dihydrotestosterone are released.
