I have just gotten 200 tabs of clen @ 20mcg. i plan to use it for fat burning purposes. i have been told that it is better to take clen 2 weeks on and 2 weeks off because of beta-receptor down-regulation. and on the 2 off weeks to take and ECA stack. is this true?....does it work?....or is it better just to run the clen for 4-6 weeks straight?
