I was just going through the Tribulus posts here. I am 62 years old and take 6 gr. of l-arginine a day, zinc, dhea 25mg, a heavy multi vitamin, omega3, edta, and Tribulus 1250mg - 3125mg,. My girfriend is 22years old so the 3125 dose is when I want to wear her out. I have never done any anabolic steroids. I suspect the posts who poopoo Tribulus are used up or taking something that counteracts its effects. I just think about something sexual and I get an erection. Have morning wood so hard that I have to wait 20 minutes to pee. I suffered from ED when I was in my early 50's. Since taking tribulus. that is just a memory. I have a 55" chest, 32" waist I am 6'1 and I do not workout. I have lifted before, and can bench 250 lbs. The Tribulus I use is no exotic just a Wonderlabs product. It is cheap. Just one guys experience>>>>>>>>>>>>>>>
