Mesterolone tablets 25mg/50 tab. 

Mesterolone (Provirolone) is one of the most undervalued drugs in bodybuilding. This  is not a classic anti-estrogen. Mesterolone is an anabolic steroid preparation, a derivative of dihydrotestosterone. According to the structure, Mesterolone molecule is very similar to Methenolone,the difference between the two drugs is approximately the same as between men and women. This drug is partially blocker of estrogen receptors. Proviron has the ability to increase the amount of free testosterone in the blood by attaching to binding globulin sex hormones, and reducing the last activity. Due to this property to increase th amount of free testosterone, many athletes use Proviron for 5-7 days in the middle of the cycle of AAS. Some researchers refer to Mesterolone more as anti-androgen, highlighting its inappropriate to apply during the reception cycle of anabolic steroids, but this is not entirely correct. Proviron is used in precompetitive preparation for increasing the rigidity of the muscles, it has an amazing ability to give muscles definition. Another Proviron feature is its ability to significantly increase the libido in men (often drug causes spontaneous erections), which makes its application simply unavoidable in conjunction with drugs, which are lowering libido (Trenbolone, Nandrolone, Norethandrolone). Using Proviron in recovery alone can not be entirely justified – here his best results will be combined with Tamoxifen or Clomiphene.
