Using clenbuterol for fat loss is a bad idea, as it was never meant for this purpose, and the dosages needed for fat loss will cause a lot of side effects. Besides, it will also eat up your lean mass - not only fat. This is not good. If you want to lose fat, better use something that was created for this purpose, such as Cardarine GW-501516 and n2Slin. Cardarine GW will preserve your muscle mass even in the most catabolic of the conditions, and will burn fat effectively. Cardarine will also give a lot of good benefits, such as enhanced endurance, recovery, and cardio performance. N2Slin is an awesome nutrient partitioner, so all the insulin will go to the muslces, not to the fat. This stack is completely safe, and will cause no side effects at all.
