First, let me start off by saying that I have no intention of taking anything discussed here.
Somebody at work proposed a study of these supplements and suggested me as a "volunteer" for some reason... why I have no idea (other than that he seems somewhat obsessed with me). I politely declined. I also did some searching and found that these drugs such as Ritalin and Adderall are on the in-competition banned substance list... basically they are stimulants.
So let me remind everyone that I have no intention of taking these, but am curious what everyone's take on them is, from a racing perspective.
