I am also using Xenedrine, but not the EFX. However, I think that I will be switching soon. The regular Xenedrine has worked well for me so far; I've lost about 20 lbs and gone through 2 bottles, but that's also with diet and exericise. However, it has gotten me over that "hump." Also, I'm pretty healthy (except for the extra 30 lbs I'm carrying around), but I know that ephedra can be dangerous. That's the reason I'm going to the EFX....It's supposed to work just as well so why risk the ephedra? But on the regular stuff I haven't had any side affects at all. When I switch over, I'll let ya'll know.
Do you have a big butt? Yeah, me too. Let's lose it together.
