most women max out at 80-120 mcg daily with clen. Newbies should start at 1/10th of a cc daily for 2-3 days then double the dose every 4-5 days till you get in the 80-120 mcg range. Build up slow, measure accurately and supplement with taurine (2-4 grams daily) and potassium. (low salt V-8 juice) cycle the clen 7-14 days on with equal time off, and use an oral fat burner on off days, or nothing at all if you choose.
