Things like caffeine supplementation, ephedrine, clen, etc fall into grey areas for me...but they are banned by the natty feds i look at.
I'm not sure I have ethical concerns with gear unless one is competing in a sport where it is disallowed or it is being abused. Abuse of any
substance which leads to a burdening of society due to health costs (I live in the land of socialized medicare thankfully) is ethically unsound in my mind, but responsible use of gear, booze, food, etc. is fine. I'm not sure I'm interested in a government telling me what I can and can't do with my body, as long as I don't impinge upon others rights...
This reminds me of a Colbert Report I saw where he was delineating the difference between Big government and Small government...
"telling you what you can do with your own body...=small government. You may say, but wait, don't I own my body? No, because then you would be able to sell it" heh...
