I used albuterol in combination with other supplements but its definitely a strong fat loss aid. I was avg about 18 mg day broken into 3 doses and the last dose being just prior to evening cardio. Not only do I think it aids utilizing fat for energy and bumping ur metabolism but it makes ur runs and elliptical work a breeze as it increases cardiovascular capacity. Great shit and a much better choice than clen which was designed to do the same thing. I truly suffer from narcalepsy when on clen but I'm shaking as I doze off lol. Kind of creeps me out.
