I've read about these two fat burners. Clenbuterol seems highly dangerous to me though since it raises your body's internal temperature. But Cytomel seems like it might be worth a try. But what happens when you stop taking it? Does your metabolism slow back down and then you start gaining weight again? Or can you use it(like I would) to burn some fat and then stop using it and hopefully maintain a lower leaner body weight? Is it safe to use for a short time?
