I don't think t-rex is worth the money. I was saving my order of it for cutting cycle but I got a little curious because of all the hype it has been getting here. So I tried one, like recommended, and not only did I not get energy or feel like i was burning up like some do, I was straight up sick the rest of the day. I don't know if it interacts with anything, only thing unusal in my diet is creatine which I was near the end of the load phase when I took the t-rex. Anybody else get nauseous from it?
