I use real ephedrine from nature.
What source?
I go to Urgent Care if I have a cold and get the good medicine that works.
Get the prescription and end up feeling well by the next day. I discovered it after getting real sick one year and the doc prescribed the following:
I was given the medication Amoxicillin for 10 days for the strep throat and about 2 weeks later Azithromycin for 5 days for the coughing.
The head cold and coughing are gone but the throat still felt tight. It was a month and I still had that frog in my throat.
I was given Prednisone to treat the throat tightness which relaxed the throat and got rid of my stiff neck.
Also the pain in my shoulder and back went away and stayed away.
