I've never used either of these substances, but I have considered clenbuterol for fat burning. But, I haven't tried it yet because the only places I can find are fairly expensive. However, I've also heard that salbutamol is an effective fat burner too and I've found places that sell it for much, much less than what clenbuterol costs. How would you guys and girls rate salbutamol as a fat burner? Thanks
