Just wondering in real life what kinda negative sides do you experience while taking any of these . I have only tried viagra and some stuff over the counter. The sides are exactly the same with both maybe a little worst with the otc stuff which I am all most sure its spiked because its works all to well for just being some herbs .lol Neg Sides for me Flushing of face, swelling of face and hands the next day, and I am not sure 100% but it almost seems like I am depressed the next day after taking. I think to my self every time the day after man its not ever worth taking them. But of course give it a little time and I forget and wanna perform like a champ again.
