Diet is first , then training do cardio in the morning on a empty stomach at target heart rate for fat loss , those 2 things do most of the fat loss also maybe if you wanted to use something a ECA stack would be good or Clenbuterol but make sure you have diet and training right first before you use eithe of those , also research them if you plan on using them for instance when on clen you have to supplement your body with taurine and potassium
