In many ways, Proviron is a very unique anabolic steroid. It shares some strong similarities to Masteron (Drostanolone) and to a degree Anavar (Oxandrolone) and Winstrol (Stanozolol) but in totality it is its own unique animal. In a performance capacity, Proviron is not used to promote large buildups in mass, although it can serve an important purpose during such a phase of training. We will, however, find Proviron to be far more common in cutting cycles, but once again its purpose will be somewhat unique.
Proviron (mesterolone) is an interesting anabolic steroid, though it is not of much value to bodybuilding. It seems that the most common reason for many to consider including it in a steroid stack is for anti-estrogenic activity. In the days before anti-aromatases and the use of SERMs (selective estrogen receptor modulators) such as Clomid and Nolvadex, there was some merit to this.
The main downside of Proviron is that since it contains no anabolic properties, it will not result in much muscle growth if used alone. It truly is a “kicker” to other steroids, most notably testosterone. And although it doesn’t cause water retention, it can increase blood pressure. DHT can also increase irritability if duration exceeds more than a few weeks.
There have recently been advances in natural alternatives to Proviron. Avenacosides have been shown to lower SHBG and to raise free testosterone by as much as 20%. Since Proviron is used mostly as an ancillary substance and does not have much of an effect of actual growth, more and more people are opting to go the natural route. Although Avenacosides won’t work quite as well, they are effective and can be used in conjunction with a lower dose of Proviron for an even more powerful muscle hardening/libido enhancing effect.
