L-Carnitine?
I recommend taking L-carnitine to burn fat during exercise. GNC is that and makes Musashi – Is there a brand that I use? Obviously one is cheaper than the other and I really do not want to pay a fortune. No difference?
Both do the same CNG is cheaper. Get Lean and Clean powder form GNC.
