Gotcha, well for example with the Bronkaid (Ephedrine HCl) the molecular weight of ephedrine HCl is 201.69g. It is also important to note that the ratio of ephedrine molecules to HCl molecules is 1:1. 36.45g of that 201.69g is from the HCl, while the remaining 165.23g is from the ephedrine (free base = no additional molecules attached). Therefore, 165.23/201.69= .819 (81.9%).
If each bronkaid tablet is 25mg, 25mg multiplied by .819 = 19.3g ephedrine per bronkaid tablet.
And all numbers for molecular weights were just gotten from periodic table of elements.
Calculated correctly, Bronkaid contains 77.1% ephedrine base and 22.9% sulfate ions.
So when you take 25mg of ephedrine sulfate, you get 19.28mg of actual ephedrine base. And when you take 25mg of ephedrine HCL, you get 20.48mg of actual ephedrine base. Overall, the HCl form is only 6% stronger than the sulfate form.
Bronkaid comes in tablets of 25mg sulfate and Primatene comes in tablets of 12.5mg HCl. They're usually around the same price for the same number of capsules, though, so Bronkaid is clearly the better bargain. You're getting twice as much at 95% the potency for around the same price.
"OP, I think you may be a little off on your math, I just did it myself:
Free Base Ephedrine MW= 165.23
Ephedrine Sulfate: MW=428.54* remember that there are 2 "Ephedrine" (I forget actual scientific name for it's structure) molecules per sulfate ion (since sulfate has a 2- charge)
-Therefore free base ephedrine is around 77%
Ephedrine HCl: MW= 201.69* 1:1 ratio of ephedrine to hcl
-therefore free base ephedrine is around 81.9%
25mg of Ephedrine Sulfate (Bronkaid) has around 19.3 grams of ephedrine
25mg of Ephedrine HCl (Primatene) has around 20.5 grams of ephedrine
Considering Primatene tablets only have 12.5g of ephedrine hcl, it takes 2 pills of Primatene to basically equal one pill of bronkaid*
THEREFORE, as far as quality, they both work equally as well for you asthma needs.
However, as far as costs are concerned, 24 Bronkaid pills (around $5) has 483mg of Ephedrine free base
-60 Primatene pills (around 10$) has around 615mg Ephedrine free base
For me, I'll definitely stick with Bronkaid because I like saving some money!"
I'd like to bump this thread. Good info here...
So which of the two would you guys get?
haven't been able to find either here in Michigan for quite some time.

I'm in michigan and have always found it at Walmart. if you want the primatene go to CVS.
I'm in Oakland county.
So I have to go after primatene right now? Good to know, thought it was all around ephedra
