I am new to working out and eating healthy. I have always been naturally skinny, but my metabolism has slowed down with age and I recently started taking T3 to speed it back up. I wouldn't be worried about it except that I model, and I need these recently gained pounds to be gone. I am taking 100mcg every morning on an empty stomach, but haven't had any side effects or seen any difference. If anyone has information, please let me know.
