I purchased this product because of ED. I had back surgery in 2009 and I have no feeling of my penis at all. No erections, I never get hard or have any feeling.
Zyalix sounded like a good product to try. Don't do it. It made me sick after the first dose.
I'm afraid that like the others I will keep getting charged for a product that sucks. Just save your money and don't try it.
Bottom Line: No, I would not recommend this to a friend
