the only steroid i've seen that may possibly burn fat is anavar.
and even then, i dont think it will do this.
fura at a low dosage on a cut will increase anabolism, and therfore may appear like it is burning fat, but this can be said for any non aromatizable steroid, not just fura.
I've ran fura at 300mg, and it is good stuff, and i feel can be even more better at 400-500mg is where it's potential is at stacked with hd or pmag.
600mg is the starting dose if i ran it solo. possibly bumping it up to 700mg.
