Mechanism of Action and Pharmacokinetics Testosterone Enantate

Testosterone, the main sexual androgen, is responsible for the development and maintenance of male secondary sexual characteristics, exerting significant anabolic action.

This last property contributes, above all, to the acceleration of the growth process at puberty by the stimulation of bone growth and the modulation of the welding process of the epiphysis of the long bones.

In the normal man it stimulates the activity of the RNA polymerase enzyme and the synthesis of the specific RNA resulting in an increase in the production of Proteins.

Testosterone stimulates erythrocyte production because it favors the synthesis of erythropoiesis stimulating factors.
