Thanks for completely misreading my post. I never suggested that all products on the list work nor that the list covers everything that it could.
I know that. I was merely stating a fact. I never meant to suggest you thought otherwise.
Your final hypothetical is an absolute joke. In short, NO, a placebo effect is not illegal.
It's not a joke at all - you just haven't thought through the consequences of saying it is not illegal.
If I was training a cyclist to win a Grand Tour, I would use the placebo effect, just as I would use any other useful psychological trick. I would tell him that I was doping him with a new and not yet testable chemical, then fill him full of a substance that would make him feel different when injected, but not actually have any long term effect. A mild shot of adrenaline maybe.
He'd feel great, charge off into training. He'd feel that he was more competitive - and that would translate into him actually being more competitive.
So my cyclist would go in thinking
he was doping. And soon other people would think he was doping, due to his behaviour.
The problem from cycling's point of view is that this generates the idea that people are doping, which is bad for the sport. The UCI would not like that, and probably take a dim view of it. Intention to dope would probably constitute an offence, just as attempting to steal is one even if you fail.
Not all smoke has fire. I reckon there are a large number of cyclists "doping" who are actually on chemicals of almost no actual benefit at all. They are being conned by someone. Probably the trainer would be fooled too, by someone pretending to have a secret recipe. Sometimes the doctor would be fooled too - he might believe his recipe works, when in fact it doesn't.
The case for Human Growth Hormone's effect on sporting performance in adults is very weak - but it doesn't stop people using it. Nor are many steriods in use of much actual benefit, other than generating aggression. After all, how do the people going to doping doctors actually know what they are getting works? The only test is results, and the placebo effect will generate those.
Outlandish? Possibly. Except you see if wherever you look in sports. People will inject all sorts of chemicals or indulge in all sorts of behaviour solely on the assurance of others that they work. Some of it is pure comedy - some Aussie Rugby League teams have been paying good money for "energy enhancing" bracelets! Pure placebo effect.
