Sildenafil citrate aka Viagra is a highly effective steroid available nowadays. Despite the fact that the main purpose of the drug is the treatment of erectile dysfunction, it is not the main reason of its popularity.
Among athletes, this drug is known as a one that exerts performance-enhancing effect. It should be mentioned that Sildenafil citrate is officially permitted for athletes (in 2010). However, the situation could change. In such a case sildenafil became one of the banned drugs in bodybuilding, as other anabolic steroids.
Sildenafil’s Principle of Action
The main compound of the drug is molecule nitric oxide. A lot of drugs used in bodybuilding include such a molecule and are known as steroids which are taken as pre-training vasodilators. In fact, such drugs open our blood vessels. This compound exerts an effect on muscles in artery walls, and does not allow straining and narrowing of the walls. So it makes blood flow through arteries without any problems. Moreover, blood pressure is decreased since the heart works without difficulties.
