I would suggest starting at 12.5mcg of the t-3 and 60mcg of the clen.
Then work up to 25-50mcg of t-3 (don't go to high or you'll loose muscle to and bf% won't be changing) I'd suggest stopping around 25mcg of t-3. And push the clen up 120mcg or stop before that if you can't handle the sides.
Remember take in abou 40% of your cals from protein, take taurine at 1 gram a day, yohimbe at 10-15 g a day and if you can get ketofin use it, if not cycle the clen of 2 weeks on 2 weeks off and use an ECA then.
