I'd run clen by itself first, man, everyone responds differently to clen, I responded just fine, but my buddy, dosing exactly the same as me, eating at same times and everything, could barely stand it, he was shaking, jittery, sweating nonstop, etc.
Try it by itself first, and a milder option could be to use albuterol - it works well, but has less sides, as it has a much shorter half life.
If you do want to run clen for longer than 2 weeks at a time, make sure you pick up ketotifen (some people use benedryl [sp?] but I'd rather use the traditional method)
(and topical fatloss aids.. just sounds a bit unrealistic to me- however, as I said, I'm not experienced with it, and I could be very wrong)
