Finding a quality fat burner is tough. They normally don't help burn much fat at all and are used pre contest under the facade of accelerating fat loss, but in truth, and coaches normally prescribe a shit ton of them just to keep their starving clients functional. The last real over-the-counter fat burner was ephedra.
Well... That's not the whole truth. There's an even better one that you can get your hands on if you're willing: nicotine gum. But don't ask me dosages or how to use it properly. I'm not sharing.
