I've used Clen before and I'm planning to use it again for my next cutting cycle. It worked really well for me—I got down to 8% body fat with Clen. For the last week of the cycle, I also added Yohimbine, and I was sweating a lot. Regardless of the supplements you use, your diet should be well-balanced because supplements aren't magic. Also, make sure to do regular cardio workouts.
