Let's see how they compare clinically in a new. Study the study setup to compare the three big stimulants. Caffeine modafferi provincial. And methylphenidate ritalin in forty eight healthy men who had no psychiatric disorders also. These participants did not drink more than four cups of caffeinated beverages a day.
