The weakening of the AU action

Many authors, for example, A. Vasilenko, and others point to the use of Proviron and anabolic steroids (AS) of the same receptors that supposedly reduces the effect of the latter. For the first time, this information came from Dan Duchaine’s Underground Steroid Handbook II. However, the pharmacokinetics of elementary knowledge can deny it.

Selection of anti-estrogens

Often the question is raised, what an antiestrogen drug should be preferred.

Tamoxifen – this means that blocks estrogen receptors, but does not prevent the formation of estrogens. Tamoxifen is more conducive to the restoration of natural testosterone as well as a way to directly affect the pituitary gland. Among the shortcomings – slightly reduces the anabolic activity of steroid agents. It is used only during the PBC .

Proviron® increases the concentration of androgens by binding to SHBG, thus increasing the efficiency rate. Proviron However, as has been shown in studies, is not conducive to restore testosterone secretion, unlike tamoxifen. Repeatedly performed tests of hormone levels have shown that the anti-estrogen effect on the course of Proviron hardly manifested.

Considering the advantages and disadvantages of both drugs, the best course of steroids is constructed as follows (actual for flavoring speakers only):

  • Starting from 2 weeks of the course Proviron administered at a dose of 50 mg per day. Further, to control the level of estrogen to be applied inhibitors of aromatase .
  • Immediately after completion of the course, stops Proviron reception and after elimination of steroids from the body appointed by tamoxifen for 2-3 weeks at a dose of 10-20 mg per day.
