Yeah, Adipo are some potent pills as far as ephedrine is concerned. 25mg Ephedrine/100mg caffeine per pill, but for only $20 for 180, it's one of the best deals. I think the most potent pill I have come across so far are the Yellow Jackets made by the same company that does Stacker 2. The JY contain 300mg caffeine, and 25mg ephedrine.
