I think that if the OP wants to use Clen he should, this thread has gotten highjacked numerous times

It's not a big deal or anything (it's not my thread

) I'd just remind you that he asked for recommendations on dosage and duration. I've used clen on a few occasions and haven't ever had any negative experiences. It is a very harsh compound and not something to be taken lightly (I know that this is what you guys are trying to get across)but if you follow the suggested protocol of slowly increasing dosages until they become overly uncomfortable, then decrease slightly, there should be no reason to have any nasty sides. As for the long term sides, I think that the media is attacking this just like they are attacking AAS. I'm not saying that the stuff is safe, but i've haven't seen proof that responsible usage is dangerous.
