In case someone is thinking ECA is a new drug created for one purpose that is not true.
Ephredrine is the same dosage and makeup Primatene Asthma medication minus guaifenesin
Primatene: Each tablet contains ephedrine hydrochloride, USP 12.5 mg and guaifenesin, USP 200 mg.
a typical ECA tablet: Each dosage should contain about 24mg of ephredra from a standardized portion of Ma Haung extact (so much Ma Haung yields X amount of ephreda).
Then 200mg of caffeine is added to each dose to produce a thermalgesic effect.
The aspirin is of no real weight loss value, but it helps with the increased nasal activity (post nasal drip happens with some people) to combat the headache.
Now the problem was and still is people are taking 40mg+ at a time....this is one of those drugs that at 20/200mg you are obtaining the full benefit....sort of like anesthesia....so much you are unconscious thats all you need....however keep raising the concentration and soon you will go into coma or cardiac arrest or ??? death would be emminent.
Removing Ephredrine from the shelves is another case of the stupid asking the government to step in and prevent more stupid people from dying.
