Another clen ?

[Ty]

I heard that clen opens the airway and allows people with asthma to breath easier. What about for a normal person while running..would it help stop me from huffing and puffing?

I don't know about everyone else but it did seem to open my airways more making it easier to breath while doing cardio

The huffing and puffing isn't from constricted airways in a normal person. It's from an out of shape cardio-pulmenary circuit. Increased frequency of cardio will help that.
