The EFX one doesn't have any ephedra, it uses some kind of a substitute for it. Anybody tried both and can really tell the difference? I'm ordering right now, and don't know which one of the two to pick. Thanks!
use the RFA. its the tried and true one. they are pushing the ephedra free since the FDA is on everyones ass and they want people to use that version so they can satisfy the FDA and have an ephedrine-less formula. don't let anyone fool you.......ephedrine/norephedrine are the key fat burning components with yohimbe right behind.
I work at GNC and I've heard only negatives about the EFX....the RFA 1 is the top selling product in the store by far...thatll tell you everythign you need to know.
first thing i sell at my store everday is xena-fucking-drine. and people complain about the EFX cuz they buy it by mistake and say it didn't do shit for CNS or for fat loss. i prefer clenbutrx or NYC or MD6 myself. get one with yohimbe in it. trust me.
If energy is your main goal they both work fine.But if fat loss is what your looking for your probably better off going with the one with the ephedra in it...
