do you mean the new Xenadrine EFX?
With no Ephedrine?

If so.. It works really well.. I've been using it for a month and have noticed significant fat loss with zero sides.

It seems like it was the little extra boost to really get the fat melting off, after the cardio results started to taper off.

Don't get me wrong. Cardio and good diet are the key to trimming but this stuff has really helped.
