Hey everybody,Bronkaid contains 63.24% of pure ephedrine and 36.76% sulfate ions.
Primatene contains 81.92% of pure ephedrine and 18.08% hydrogen chloride ions.
If you don't feel like reading this post, all the information is at the top in quotes.
Bronkaid and Primatene are ephedrine-containing products that are most often used is conjunction with caffeine to create the "EC Stack" for weight loss but are not supposed to be used for this purpose. This is also not the purpose of this topic.
There is always people saying "Oh primatene is stronger than bronkaid" or "Bronkaid is really 1/3 as strong as Primatene" without any real basis.
Each Bronkaid pill has 25mg of ephedrine sulfate, but in reality only a little under 16mg of that is pure ephedrine. Each Primatene pill contains 12.5mg of ephedrine HCl (which means you need 2 pills to reach the "25mg" standard) but in reality this pill is only a little over 10mg of pure ephedrine.
So 1 dose of Bronkaid (25mg) is equal to ~16mg of pure ephedrine. 1 dose (two pills) of Primatene is equal to 20mg of pure ephedrine. This means with Bronkaid you are actually losing out on 4mg, which is a 20% decrease from Primatene.
These are empirical facts that are based on simple calculations that anyone who took high school chemistry can do.
If anyone would like to read how I came up with this information I can PM them the pastebin link... because I can't post links yet!
If anyone has any questions, comments or concerns feel free to post them!
