Finally, the third thing Viatropin does is enhance the libido. When testosterone levels start to go downhill, so do the sex lives of most men. Not only is it harder for them to get an erection, but maintaining erections is extremely difficult, as well. Viatropin increases the blood circulation throughout the body, giving it the oxygen it needs to function optimally. This increased blood flow aids the libido, which controls the sexual drive in men. Not only will users no longer have erectile dysfunctions, but their performance levels will greatly improve.
