I'm trying all three seperatley. I've already tried out Ephedrine. Got a bottle of pills from a gas station. Took 4, then an hour later 6 more, for a total of ten. The brand was Ephedrine plus, and each pill had 12.5mg ephedrine. The results weren't bad. Just less than I expected. I got a different bottle from the gas station tonight. This one is Pseudoephedrine, with each pill containing 60mg pseudoephedrine. I'm concerned on the amount I should take. Seeing as how 125mg of ephedrine didn't do too much for me. Is there much difference or any at all between pseudoephedrine and ephedrine? And also, do local herbal/health food stores sell ephedra in it's natural form?
