Can athletic performance enhancing effects be achieved by using an albuterol inhaler? Or does it need to be oral tablets?

From what I've seen the recommended dosage for albuterol and sports is 4mg 3-4 times a day.

Inhaler version albuterol only delivers 100mcg per puff which means one would have to consume 40 puffs to equal 4mg. Is this correct? Doctors recommend 1-2 puffs, 3-4 times a day. Doesn't seem realistic.

I'm interested in both cardiovascular benefits as well as stimulant benefits.
