I believe what professional cyclists tell me. They are to be trusted.
You're okay, I've taken my iron supplements and know you're being ironic.
Do try and get this: no one is saying riders are to be believed, that riders are to be trusted. You're over-stretching to get there, as is your wont. In fact, we know that the sport encourages them to lie, to sandbag, to say they feel good when they feel bad, happy for a rival's victory when they'd love to cry, all sorts of lies. We know from experience, good and bad, they are not to be trusted.
We also know, from years of experience, that riders believe all sorts of things improve their performance, from plastic plugs up their noses to all sorts of legit products in finishing bottles (Champagne, quinine, etc). None of this stuff needs science to support it for them to do it. They do it because
they believe it works. Calling into question whether a product works or not does nothing to challenge whether that product is used.
