I was asking myself the same question the other day. I got a bottle of clen that I may use when I start cutting in 7 weeks. I have never taken clen and i'm not sure how i'll react to it. I was thinking about taking Lipo-6 for 3 weeks or so then stopping it and starting clen. I was able to cut a good deal of weight on Lipo-6 last year so i'm thinking that I shouldn't rush into taking clen right away when I can get by with a normal fat burner and cut some weight in the first few weeks. Does that make sense to anyone?
Oh and I love Ephedrine. Back when it was legal I used it for cycling all the time.
