Forget the waivers. If the players are found to have taken prohibited substances, waivers wont help them one iota.
You cant simply indemnify yourself from ASADA sanctions by signing a waiver, and then taking a substance offered to you by a third party be that third party a doctor, sports science guy, coach or whomever.
The player will be banned. He can then sue the crap out of the person that administered the gear to him, but it wont protect him from the ASADA sanction.
The only effect those waivers will have (assuming the substance taken was prohibited) will be to possibly reduce the length of the ban from 2 years to 1 by evidencing the fact that the player genuinely did not know that the substance taken was prohibited.
See my post above.
If the document refers to "Y legal drug" then there is a very strong defence that it was reasonable for the players to rely on the advice and take the administered Y (where they had not reason to suspect that Y wouldn't be Y).
I'd say that this doesn't stop it from getting very messy for the club.
