If you aren't feeling anything at that dose if Albuterol, you definitely have some bunk stuff. That's the risk you take with a lot of these other companies. I know AG Guys has Albuterol out of stock, but their stuff sells out so fast for a reason. Its extremely powerful and awesome stuffJust updating on this. Since ag guys didnt restock I went ahead and purchased albuterol from . Im on day 4 @ 12 mg/day and I dont feel anything different at all.
