Although i haven't used pill form, I do have asthma and it's one of my meds. It's a bronchodilator. It opens up airways. It also has a stimulating effect. Dylan did a vid on it. That's actually how I found him and his videos several years ago. I think the main point is that it's safer than clenbuterol. Clem can give you heart problems. I don't think Albuterol can/does. It's definitely used for cutting/dropping bf.
