Ephedrine HCI vs. Sulfate Effects
I have been experimenting lately with ephedrine products(both Primatene and Bronk-Aid). I have found that 12.5 mg (half tablet) of Bronk-Aid makes me very jittery and nervous, whereas I can take two Primatene tablets (25mg) and feel none of those side effects. Are the sulfate and HCI variations of ephedrine that different? My understanding is that they are close to being equal in terms of potency.

I am the exact opposite. For me, 25mg pure HCl is highly anxiogenic with a very noticeable pressor effect. Ephedrine sulfate has essentially no effect on me. Very interesting.

I can tell you my body has always responded strangely to stimulants. For some reason, the pure synthetic versions of stimulants have always seemed to be easier to handle. I know I can take 5+mg of Yohimbine with no problems, but Yohimbe bark extract made me feel like my heart was going to explode. It was the same thing when I tried using MaHuang about ten years ago.

In reality, there is, because there is a pharmacokinetic difference between the two salts (beyond the scope of this conversation: the quicker you saturate the blood, the greater capacity for permeability is realized).
Ephedrine HCl has a "common ion effect" in the gastric lumen which pushes the equilibrium towards the salt (see: LeChatelier). The end effect is a blunting of ionization, which allows greater absorption in the proximal duodenum simply due to kinetics.

I appreciate the resource of "nerds" as opposed to the brotelligent. It is quite refreshing. It is quite nice to learn something (again) in this community once in a while. Thanks madchemist!

Man, the science in this thread is making my head explode - but it's good stuff!
For me - I prefer Ephedrine HCL and, I also use Yohimbine HCL.
Ephedra and Yohimbe were so confusing to me because nothing was standardized. With the HCL's - I know exactly what I'm getting and I'm less likely to kill myself with these substances! LOL

I completely agree. Even though the science is way over my head, it's good to hear from people like madchemist who have a working knowledge of how these substances actually work. I've always believed from personal experience and reading a lot of anecdotal feedback that Ephedrine obviously works, but until recently I had never even heard of different forms like HCl and sulfate.
So far so good, though. I took 25mg twice today (with about 100mg of caffeine) and with no significant anxiety or excess stimulation.

man i cant wait to get back in school and get into that chemistry again
The difference between who you are and who you want to be is what you do.

Ok just got some Bronkaid 25mg of sulfate though it was HCI. Is the Sulfate as good as the HCI and is 3 25mg a day right? Thanks
