Above quote from David Wells. Mike Piazza says the same.....and I've read it elsewhere several times.
Also..."Many MLB players are also known to use stimulants, including Ritalin, Dexedrine and Adderall. The use of amphetamine in baseball is well documented ... even Pete Rose admitted to using them in the 70’s. Players also use many “natural” and/or OTC performance enhancing products that contain caffeine and ephedrine."
