After reading and doing some research on clen (from this site as well as other sources), I decided to get some clen and try it out. The goal was to lose weight and cut. I weigh ~150 lbs and want to get to 140. I am an avid biker and do some lifting in the off season. Bike around 200 miles a week. After taking clen for a week (20g, 40g 60g and so on), I did not notice any weight loss at all. Plus I lost a lot of power climbing hills which I can normally do fairly easily. I take clen with Taurine as suggested, but that is not helping either. Any suggestions?
