Although Clenbuterol is one of the best fat loss aids that I have ever tried, I can give my best experience with clen. Use it during your time off between steroid cycles (during PTC and after) and the normal losses that can be experienced will be the past. Dosage can vary, 40-60 mcg per day, two days on and one off is my favourite. The best clen product I have ever used is Bulgarian Clenbuterol by Nihfi.
