Proviron is composed of mesterolone dosed at 25 mg per tablet.

It is not an anabolic but a very powerful anti-estrogen.

Proviron acts as an anti-aromatic: it prevents the aromatization (transformation) of anabolic steroids into estrogen. It thus avoids gynecomastia and can be combined with Novaldex to increase its effectiveness.

It should indeed be specified that Proviron and Novaldex are two anti-oestrogens whose mechanisms of action are different and complementary, and it is for this reason that the association of these two products is so effective: while Proviron prevents the anabolic aromatizer, Novaldex clogs estrogen receptor cells, preventing it from working.

It is therefore a formidable tandem.

Proviron is also not only an excellent anti-estrogen: by maintaining a low level of estrogen, Proviron also reduces water retention.
It thus gives the user the skinned look sought after by so many bodybuilders, especially when preparing for competitions.

It should be noted that Proviron tends to limit muscle gains from a steroid cycle, as it attaches to androgen receptor cells instead of other steroids in the body, which then get stuck on the outside. and therefore without effect.

This is why many bodybuilders take a minimal dose of Proviron, just to avoid gynecomastia. As for mesterolone side effects, they are rare below 100mg per day.

Indeed, the tablets of Proviron are not alpha-alkylated 17 and do not present any harmfulness for the liver.

On the other hand, if we start to exceed 75 to 100 mg per day, we frequently see phenomena appear such as priapism in men or virilization in women.

We cannot emphasize enough that if the side effects depend on the product used, they depend even more on the dose used and that the bodybuilder who decides to take large doses of the products mentioned in this book does so at his own risk and peril.

Anti-estrogen stack: Proviron + Novaldex. 1 to 2 tablets of 25 mg per day are enough to prevent gynecomastia.

Proviron is manufactured by Schering laboratories in tablets of 10 or 25 mg, the latter being the most common.
