Proviron is actually one of the oldest anabolic androgenic steroids on the market. It is not the most powerful anabolic steroid, however, it is still a very beneficial anabolic steroid. It shares similarities to Masteron, Anavar and Winstrol, but overall it is very unique. Proviron is not used to promote large buildups in mass, however it’s far more common in cutting cycles. Among athletes, Proviron is primarily used to increase androgen levels when dieting or preparing for a contest.

Proviron effects

Proviron is best during the cutting phase. It has the ability to enhance the hardening effects of other steroids. It will also enable the individual to burn body fat at a far more efficient rate. Due to the anti-estrogen effect of Proviron, the individual will be less prone to water retention and it could eliminate the need for a traditional anti-estrogen.

Thanks to the enhancement of circulating free testosterone, Proviron has great benefits when testosterone levels are low. In fact, with a low dosed testosterone cycle that includes other anabolic steroids, the total results will be greater for the individual who includes Proviron compared to the one who does not. In the end, the primary base benefit is the increased androgenicity of other steroids being used in order to promote a much harder and far more defined physique.

An added benefit of Proviron is its ability to have a high affinity for SHBG (Sex Hormone Binding Globulin), which is a protein that binds to anabolic steroids in the bloodstream (namely, Testosterone) and renders them completely inactive once bound. The use of Proviron in this case alongside other anabolic steroids may magnify the activity and effects of other anabolic steroids through this pathway, leaving more unbound and free Testosterone to perform its job.

A well-known benefit of Proviron is also its ability to act as an anti-estrogen via its activity as an aromatase inhibitor. It should be noted, however, that its activity as an aromatase inhibitor is not regarded as strong as Aromasin, Arimidex, or Letrozole, but it still works and can be used as such.

Proviron administration

In a performance capacity, Proviron doses normally range from 50-150mg per day. Most men will find 100mg per day to be the minimum beneficial dose with both 100mg and 150mg being highly effective. Total use will normally last between 8-12 weeks.

Proviron stacks well with all anabolic steroids. During the cutting phase, it will be most beneficial in conjunction with steroids like Anavar, Masteron and Winstrol as well as Primobolan. It will greatly promote the androgenicity of these steroids in order to provide and promote the hard look desired.

Proviron side effects

Proviron carries one of the highest safety ratings among all anabolic steroids. Most men will be able to use this steroid without any negative issue, but some possible side effects do exist.

The Mesterolone hormone does not aromatize and it carries no progestin nature and thus side effects such as gynecomastia or excess water retention should not occur.  This will also greatly reduce the risk of high blood pressure as high blood pressure associated with anabolic steroid use.

Androgenic side effects of Proviron include acne, accelerated hair loss in those predisposed to male pattern baldness and body hair growth. Such effects are highly dependent on genetic predispositions.

Due to very high virilization, Proviron should be avoided by females. This will include body hair growth, a deepening of the vocal chords and clitoral enlargement. There are other steroids that carry much lower virilization ratings such as Anavar and Primobolan.

Proviron can negatively affect cholesterol at a far more pronounced rate than most anabolic steroids. If you suffer from high cholesterol you should not use this steroid. If you are healthy enough for use you will need to keep a close eye on your levels.

All anabolic androgenic steroids are suppressive to natural testosterone on some level. Mesterolone hormone however does not significantly reduce  natural testosterone production. Due to minimal testosterone suppression, it is possible to use this anabolic steroid without exogenous testosterone. An individual could implement a cycle of Anavar along with Proviron and keep his testosterone levels from falling to a very low testosterone range. However, most will be using other anabolic steroids that are highly suppressive to natural testosterone production along with Proviron making the use of exogenous testosterone imperative. Regardless of the specifics of the cycle, once all anabolic steroid use has come to an end natural testosterone production will begin again. Users are encouraged to implement a Post Cycle Therapy (PCT) plan at this stage.

Proviron is not hepatotoxic and does not cause any stress or damage to the liver.

Why buy Proviron

Buy Proviron, a synthetic, oral androgen with no anabolic characteristics. Many athletes often use Proviron at the end of a steroid treatment to increase the reduced testosterone production. It also successfully blocks water retention in the body, which is the most common side effect of many anabolic steroids.
