I have commented before on how offensive posts like this are for so many reasons. It ususally turns out to be me against the world. So I don't even bother anymore.
But now that I saw your question, I decided to throw my 2 cents in (again).
AFAIC, with few exceptions, everything we do is a marathon, not a sprint. So using crutches for sprints is, at best, myoptic. Any stimulant, I don't care which (food, drugs, etc.) has another side, i.e., what goes up must go down. One of the commenters on OP's site talks about this much better than I can.
I really don't care what anyone does in private. But setting aside all the ethical, medical, and legal considerations, here is my biggest concern: Lots of people come to this site to learn and exchange; I'd hate to have them walk away with the idea than drugs are a good idea for their startup, just from the feedback of their peers. That's irresponsible.
