Hey guys. I started taking Tribex today (testosterone Booster) and I'm wondering if any of you guys have used it before. I took took 1 pill for a few days before, but today is the first day I'm starting the 5 day cycle so I'm taking 4 pills a day. I worked out about an hour and a half ago and I felt like absolute shit. I was sweating my ass off 15 minutes into my workout and was really fatigued. Also my heart rate was way up. Anyone used this before or know anything about it and whether or not there are negative side effects? The main ingredients are the Tribex Formula (not sure what that is) and BioTest Super-concentrated extracts (tribulus terrestris, vitex agnus casus, eurycoma longifolia). Thanks in advance.
