I like Albuterol more, but only because it has fewer sides. I feel clen works better for fat loss (though I have no data to back this up). Clen also helps me concentrate similar to Ritalin, and Albuterol doesn't.It was a mistake made by me, the site listed it as clen but the active ingredient was listed as albuterol. From what ive read, they are very alike besides the dosing. Can you please clarify the differences you speak of? And which would you prefer?
