I want to use T3 to cut my bf% (I am at 22 want to be below 16) but can't use any gear as I will be taking an extreme blood test that tests for anything and everything. I also can't use Clen as my body doesn't respond well to it whenever it is dosed over 40mcg, which is barely enough to do anything. What can I do naturally (ie diet, workouts, supps) to keep from losing lean mass?
