so does salbutamol sulphate=ephedrine sulphate??
No, they are two different substances. I have done both many times an I'd say that ephedrine is better at burning fat, but salbutamol (albuterol) is better for performance enhancement, as in helping you train harder and breath easier.
(My opinion based on the way i react to both substances is): Salbutamol does have some thermogenic value, but start SLOWLY and work your way up. It really does help, but it's no magic pill.
