Testosterone does not burn fat, and steroids should not be used for that purpose. While they can help you lose fat, they do so just by allowing you to workout more with more intensity. If you want something that was created specifically for fat loss, your best bet would be Cardarine GW-501516 and N2Slin. Cardarine is a very good recomp compound that will burn fat and maintain your lean mass, and even increase it. It is a very good compound because unlike steroids it will not cause side effects, it is non-hormonal, and it requires considerably less ancillaries. N2Slin is a very good nutrient partitioner, which will send more insulin to the muscles, so less will get converted into fat. This combo will give you very good results in the safest way.
