Viagros (Sildenafil)

• Active ingredient: Sildenafil citrate
• Type: Selective inhibitor of specific phosphodiesterase type 5 (PDE5)
• Form: Oral (pills)

Sildenafil is a well-known enhancer of erectile function in men, commonly sold under the brand name Viagra. However, this drug has recently gained popularity in both medicine and bodybuilding. While it does not directly affect nitric oxide levels, sildenafil promotes the expansion of blood vessels in the muscles and pelvis. By blocking the enzyme PDE-5 (phosphodiesterase-5), which breaks down nitric oxide in the blood flow, sildenafil increases its concentration, resulting in vasodilation. Although the drug was originally developed for cardiovascular issues, it exhibits high specificity for pelvic organs while being active throughout the body.

The use of sildenafil in bodybuilding offers numerous benefits that make it profitable and effective. The drug slightly lowers blood pressure, positively affects the heart, improves blood flow in the muscles, and causes minimal side effects. One notable effect is an unprecedented pump, leading to mechanical stretching of muscle vessels and fascia, indirectly contributing to the growth of target muscles being trained.

It is important to note that some individuals mistakenly believe that taking sildenafil causes a permanent erection, but this is not the case. Without sexual arousal or stimulation, an erection does not occur. A study published in the Clinical and Translational Science magazine suggested that sildenafil could increase muscle protein synthesis and reduce muscle fatigue, potentially improving skeletal muscle function.
