Experience with combining Clen and Ketotifen?

I've personally used Clen with and without Ketotifen, but when i've used these two drugs in combination the sides of clen were completely eliminated, but my gains were completely eliminated too... I was using clen for 3 weeks 1 week off at the time, thinking that with constant intake of ketotifen at 4 mg/day the receptors would be upregulated pretty easily.

I know that in theory ketotifen is supposed to increase the effectiveness in clen, but in practice it seems to have neutralized it... Now i'm debating whether to do a normal 2 week off 2 week on cycle, with ketotifen only in the off weeks.

Does anyone have the same experience? Maybe i think that clen isn't working because i'm not experiencing any sides while on ketotif? :unsure:
