I've been reading into clen lately, I haven't decided whether I want to try a cycle of it or not. I just like being knowlegable about everything. Everything I used to read was the 2 weeks on/2 weeks off and then i started reading about 6 weeks straight with benedryl on weeks 3 and 6. I then read that the benedryl doesn't really do anything and that taking ketotifen upregulates the receptors.

There are so many mixed opinions out there about clen, my question is what is everyones opinion on the best way to use clen and where can ketotifen be purchased?
