ephedrine hcl vs. sulfate??

hello guys!
i ran out of vasopro and i went to the local store and found “bronkaid” and it contains 25mg ephedrine sulfate .
now just wanted to ask you guys in the know if and what are the differences between ephedrine hcl and ephedrine sulfate?
i did a search but couldnt seem to find any info on it.
i didnt wanna use anything else cause they were all twice the price for have the amount.

thanks alot!!
