Hey, i often use ephedrine hcl for studying. it really is a great herb, focus is superb. but it has recently become banned so it is hard to find it. But i can get seeds for mahuang, which you then dry and eat(1g should have 22mg ephedrine alcanoids).. but i heard that mahuang has other alcanoids which inhibit the ephedrine in the plant, so it is not the same as ephedrine hcl.
can anyone confirm this? (i dont want to grow the plant and then find out it's useless)
thanks
