How many boxes of Ephedrine (Primatene/Bronkaid) can I buy in 30 days? I’m running an EC Stack for the next couple of month and kind of confused.....

I live in Illinois and under state law......We are only allowed to be sold 7,500 Milligrams of Ephedrine per 30 days.

I usually buy the Primatene, 65 tablet boxes at 12.5 of Ephedrine HCL per tablet.......this comes up to 812.5 Milligrams of Ephedrine per box.

Does that mean I can legally buy 5-7 boxes of this stuff with no problem?

Thanks!
