I have been debating on trying one or the other, but not sure which. My question is being and athlete were running is abviously important, would the albuterol be better than the clen? I read were clen could have an effect negatively towards oxygen intake during exercise. Is that mainly for long distance or short distant bursts(which I am most interested in)? If I missed the answer in my research, please send me the link and I will read.
