I have been taking the old oxyelite pro and tomorrow I'm down to my last pill, but they were left over, only taken it 11 days, just want to know which is the best fat burner, oxyelite pro or CLA? I have GNC ripped vitapak program that has CLA and some other stuff in it

which is a more effective fat burner? cuz i heard CLA also helps build muscle and that oxyelite burns it
