Provibolic 25 mg also known as mesterolone is used mainly as an antiestrogen. It acts as an aromatase inhibitor in the body preventing or slowing the conversion of steroids to estrogen.

The anti-aromatization effect is preferred since it is more direct and efficient in dealing with the problem of estrogenic side effects.

Most athletes prefer to use Proviron 25 mg and Nolvadex (Tamoxifen), especially during heavily estrogenic cycles. With each attacking estrogen from different angles, side effects are often minimized.

Provibolic 25 mg is especially beneficial when anabolics such as Winstrol or Oxandrolone and Primobolan are being used alone since the androgenic content of these substances is relatively low.

Provibolic 25 mg can supplement a much-needed androgenic load and give an increase in muscle hardness and density.




The typical dosage for men is 1 to 2 25 mg tablets daily and is used frequently throughout a heavy cycle.

Women with a 25 mg tablet will efficiently reach the androgen/estrogen ratio and can have a great impact on the physique.

As mentioned before, it is frequently combined with tamoxifen when taking strongly estrogenic steroids (Dianabol, Testosterone), etc.
