Straight, 59 year-old, active sex life with my woman, and with ED concerns the past 20+ years. Sildenifil pretty effective generally speaking (90%) till more recently teetering off enough to jerry rig with a cock ring. Just started utilizing Trimix last week... and the experience is like Sildenifil on meth. A complete game changing experience that's still pretty hard to believe. The dose for me is only 15 units ( 0.15 ml) that only runs me $4.55 a dose... so very inexpensive. Only drawback is that this can't be utilized more than 2-3 times weekly.
