High doses of testosterone increases the number of androgen receptors in muscle fibers

   What is a molecule of testosterone, you know, once again we are on the characteristics of its structure will not stop. Just recall that by virtue of these features easily aromatize testosterone, that is, converted to estradiol. Besides estrogen testosterone by the enzyme.  Reductase is easily converted to dihydrotestosterone (DHT), which means the strengthening of its androgenic properties (action on the prostate body hair and scalp, sebaceous glands, as well as increased libido), but the erosion of the cells of skeletal muscles.

   According to studies, the use of high doses of testosterone increases the number (upregulation) of androgen receptors in muscle fibers. Results from another study also deserve to play them here in full. Here they are: "anabolic steroids in combination with strength training provokes an increase in muscle size as a result of their hypertrophy, and due to the formation of new muscle fibers. The key to this, obviously, must be regarded as the activation of satellite cells, which significantly increases with high doses of steroids. " Furthermore, it was also established experimentally that the use of testosterone enanthate at a dose of only 3 mg per kg of body weight per week raises the level of growth hormone in the blood by 22% and insulin-like growth factor by 21%.
