ephadrine when bulking

can ephadrine be used in a clean bulking cycle so i can have cals really high and prevent some of the excess bf gain . ?

i heard its done with clen for aas pct and some b.b use t3 at 25mcg ed throughout cycle .
would this be counterproductive ?
has anyone done this for the purpose of keeping of some bf while bulking ?

I cut out all thermogenics and Metabolism boosters out of my regimen while bulking. Your metabolism should be pretty high anyway from constantly eating. If your really worried, do cardio on an off day.
