I've been taking T-Rex for a month on CKD... haven't felt this "heat" everyone was talking about. Anywho, fast forward a month later - I started upping my carbs to get ready for bulking again... wow... OK. I start sweating a bit more than usual, I think nothing of it. I finish my workout, drink my P.W.O. Ultra Fuel and pop two more T-Rex. I walk home from the gym and it HITS me. BAM, I've never felt such euphoric heat in my life. I starting talking to myself and repeating "holy shit - holy shit - holy shit" over and over again. I had chills all over my body, I was sweating like crazy and I looked more ripped than ever. I'm an AF customer for life.
