Formoterol Info/Experiences?

Hey i recently heard about this product, but didnt find any personal experience with it. apparently its like clen but with less heart issues. does someone know anything about it

Astma drug pretty similar to clen, suppose to be less sides than clen or albuterol, because it effects the receptors in the heart less, same effects as clen and a similar half life, the one problem is sourcing, newer drugs are always going to expensive, so unless you know someone who has a script it might be harder to get than you think, Formoterol was the drug made after clen was deemed too unsafe to the heart
