Work on your reading comprehension, wejo. I didn't "draw" any "line" at injections. Although it was the only modality I described in my post, your inference that I find any other modality acceptable is unwarranted, and incorrect.
"Vitamin B shots are/were common." --Yeah, for @ssholes.
reader of the forums: "Taking something, even if it is not banned, for the sole purpose of shaving seconds or minutes off of your PR (as Salazar thought this would do), is highly questionable." --This is another way of saying that Ritzenhein is an @sshole.
That one guy: "Before a race I'll drink a pot of coffee, drop a few profins, put on my compression socks, and pound a couple of Gu gels along the race course. I would be lying if I didn't admit to smoking a bowl a few times out in the parking lot before the race" --That makes you a loser to me, and an @sshole to your competitors, unless it is distinctly more recreation than competition; in which case you're just a loser to everybody.
Baconn: "Even if it's a legal PED, it's still just that, a performance enhancing drug, and any honest athlete dedicated to being the best based off of their own work should stay away from them." --Translation: "Don't be an @sshole."
P. Henry: "Get over yourselves and take your phony sanctimonious attitudes elsewhere" --Spoken like a true, not to mention stupid, @sshole. I'm sure there's something you can take to feel better.
No NOPers: " Infusing yourself with a substance to gain an advantage is beyond the pale." --Translation: People who do this kind of thing are @ssholes.
Harrison bergeron: "I'm fine people training and preparing in their own way. It's part of the game. Carnitine is no more a ped than is vitamin c. --Translation: I'm an @sshole, and I feel comfortable around others of my kind. If it's not a ped, then why take it? Right.
WADA Willy: "How about people that ingest or snort stuff to enhance performance? Are they also dopers?" --They are definitely @ssholes.
SMiLE: "taking drugs solely for this purpose (to improve), even if they are legal, is behavior worthy of condemnation." --Translation: Anybody who does this is an @sshole.
Stench Test: "How about we say, if you do something as part of your training and you would feel wrong or sneaky or guilty if any of your rivals saw you doing it, then it doesn't meet the criteria of "ethical". If you do some type of preparation in secrecy that you wouldn't want to do whilst milling around in the starting area of a race with all your competitors, that is also probably not ethical." --Translation: Don't be an @sshole.
The bottom line: Those who think they are "unfairly inadequate" are LOSERS, and those LOSERS who address via these means the need for a better self-image, are A55HOLES.
