I purchased Zenerx for my 50th birthday, ordered more and took it for 6 months according to directions, but I had to quit after 6 months. It did seem to kick up my sexual desire, which was nice.
It did not increase my *** or erection size. BE WARNED: I gradually got significant joint pain in my knuckles, increased neck and back stiffness, and it aggravated inflammation that I already had, like in my feet. Six months after I stopped, some of the pain has decreased, but some seems permanent.
My knuckles seem arthritic now. I will discuss with my doctor on my next visit.
