You can find ephedrine
here. Caffeine tablets can be bought in the medicine isle of any department/grocery store (IE NoDoze). Coffee and soda do not count as dietary caffeine.
I recently started taking ECA at 25/200/325 twice a day and I've noticed good results so far. The only side effects I've noticed is a slight appitite suppression and I feel a little warmer after about an hour. Also note that I had a physical last month so I know that my blood pressure, etc is healthy.
