THE BEST SIDE OF VIAGRA

Sildenafil is a strong and selective inhibitor of cGMP-precise phosphodiesterase form 5 (PDE5), that is responsible for degradation of cGMP during the corpus cavernosum. The molecular composition of sildenafil is comparable to that of cGMP and acts to be a aggressive binding agent of PDE5 inside the corpus cavernosum, resulting in additional cGMP a
