I just read a nice article about clen where it says.. the usual conventional 2days on 2 days off is wrong and it indictes that 1 week on and 1 week off or to even two weeks on to two weeks off is much more successful. It says that people that get no results from clen should try using it by this system. the whole idea is clen half life is mistaken so this way it is more effective! Can anyone give me opinion on this with past experience.
