can someone explain to me why clen needs to be taken sporadically?

ok clen has a very short half life. why then should it not be taken ed for a month or two? im no newbie im just interested in knowing why clen is supposed to be used 2 weeks on/2weeks off or 2 days on/2 days off.

clen has a long half life, for an oral, about 35 hours; which is why the 2 days on 2 days off format is bunk.

2 weeks on and 2 weeks off is because your receptors stop responding, and need to recover. (Kinda like how people who take ECA for too long have to take more and more to get the same effect, which can lead to big problems...)
AustinTX is right. But to add to that, you can take ketotifen, which up-regulates the receptors that clen down-regulates.
