I am currently starting my 2nd week of clen at 130mcg a day. I've been on for a week, and let me tell you.. holy shit. I am adding this to a 600mg a wk Sust300 cycle with 50mg ed of Winstrol (winny). I noticed body fat disappearing at like day 4. The only negative side effects I am showing are the shaking and lack of sleep. I work a third shift job so it is hard for me to sleep during the day as it is.. I had a few busy ass days last week and I was up for 36 hours straight, slept for 5 hours and was up again for another 16 hours with a workout in there with no problem. I feel like this shit is stimulating my brain hardcore. It definitely works!
