Hi, I have started using jack3d during work outs after a friend of mine advised me about this, but now I heard that there might be dangerous side effects? I have taken jack3d a couple of times now but haven't noticed any bad side effects, or any side effects at all. What is your experience with jack3d?
I have heard about people getting vasculitis, heart palpitations, aggression, high blood pressure, dizziness, constant headaches, and feeling plain weird. If I were you, I would quit using jack3d straight away. You never know what will happen to you if you keep using it. Besides, there are much better products on the market.
