I've been taking T3 now for 10 days. I went from 25mcg/day to 75-100mcg/day. I'm getting no sweating and no shaking. This are the Greek T3-50 pink tabs. But not even that.. my bf did not change and I didn't loose any pounds. I've cut my calories to below BMR and doing half hour of cardio each day. I'm also taking ECA with it. 10 days - no results... :-(
