Perry we can talk in more detail about it. The thing is with fat burners, none will work without 100% everything else. And even then they are no where near as effective as the right diet and training anyway.

If you plan on doing a sport where drug testing is involved then none of them are really worth it.
However, if you are not doing drug tested bodybuilding, strongman, powerlifting or any other sport at serious elite level, then you will not be drug tested and there are lots of legal supplements from reputable companies that are much more effective. For example Sida Cordifolia by CNP. Top company. A herbal ephedra based supplement that really does burn fat. Others are Grenades, T5 etc. Like I said can discuss more if needed.
