I have tried this once before, but figured I'd give it another try. I began my clen cycle w/ about 60mcg the first day, with 3-6mcg of ketotifen at night (from liqua-c.) If the ketotifen is supposed to clean your receptors, then why do I have to keep adding about 20mcg every day to get the same effects? I do not notice any difference from a normal (ketotifen-free) clen cycle.
