Xenadrine RFA-1 was originally an Ephedra based supplement, but has since turned to an Ephedra-free formula. The basis of Xenadrine is a simple ECA stack (Ephedra, Caffeine, Aspirin), but it is augmented by Synephrine, Amino Acids, Ginger, and other beneficial ingredients.
The two amino acids in Xenadrine RFA-1 (L-Tyrosine and Acetyl L-Carnitine) combine to act in two completely different ways. The L-Tyrosine is an adrenaline stimulant and the L-Carnitine helps your body to utilize fat as a source of immediate energy (rather than storage).
It is hard to find Xenadrine with Ephedra. The current Ephedra-free Xenadrine formula isn't quite as effective as Xenadrine with Ephedra, but the weight loss properties of the other ingredients are still there, and present fewer side effects.
