An androgenic preparation containing a mixture of different testosterone esters. Testosterone is essential for the formation of the testes, prostate, seminal vesicles, and the development of secondary and tertiary sex characteristics. Participates in the formation of the body constitution and sexual behavior, activates libido and potency, stimulates spermatogenesis, reduces the negative manifestations of male menopause.
Testosterone is an antagonist of female sex hormones – estrogens. It causes inhibition of the gonadotropic function of the pituitary gland and suppresses the function of the mammary glands in women. During treatment, masculinization phenomena can be observed.
Testosterone has an anabolic effect: it stimulates protein synthesis, enhances calcium fixation in bones, increases muscle mass, stimulates the formation of erythropoietin in the kidneys, and increases the level of hemoglobin in the blood.
In healthy men, the administration of exogenous testosterone inhibits the secretion of its own (endogenous) hormone by inhibiting LH secretion. In high doses, the drug suppresses spermatogenesis, affecting the reverse inhibition of FSH secretion.
In men with pituitary dysfunction, testosterone relieves the symptoms of hypogonadism. If impotence is not caused by hypogonadism, then the use of the drug does not work.
The testosterone esters included in the preparation have different rates of absorption and excretion, which ensures a rapid development of the effect and a long-term effect (up to 4 weeks) after a single injection: testosterone propionate acts during the first day, the effect of testosterone phenylpropionate and isocapronate begins 24 hours after injection and lasts up to 2 weeks. Testosterone capronate begins its action during the period when the influence of testosterone isocapronate and phenylpropionate ceases.
