This is not actually ephedrine.

i.e. fake

Chris, where did you get this stuff? Thanks.

No.

Unless it says the amount of alkaloids present, it is bunk.

Look for Ma Huang with a standardized extract

it will look something like:

Ma Huang (standardized for **mg ephedrine alkaloids)

if you look at the link on the first post, you'll see one or two like this

most are fake though
