Whats the best?
Primatene is hcl (Which i believe is the "real" ephedrine), while Bronkaid is sulf.
Not sure what you mean by "real" as far as ephedrine HCL vs. sulfate, but there IS a difference in absorption time and amounts as BB mentioned.
If by "real" you mean herbal ephedra, then no - you won't find that at the pharmacy.
Some companies are now selling ephedra products, but they're actually using a substandard derivative; not the good stuff that used to be available.
Then again, that's why they're legally able to sell it.
