Quote Harrigan="Harrigan"As a player, you'd trust that the supplements your employers (a professional Rugby League Club!!) give you are all above board. It's not like its some guy outside the ground handing them drinks as they walk in to the Stadium! I have no time for drugs cheats but have some sympathy for the players here.'"
That's pretty much my view too.
If its a drug/supplement/drink/food/medication etc supplied by the club I think it reasonable for a player to expect it to be legal. In the same way as when we go to the doctors and he/she prescribes us something we reasonably assume it is both legal and safe for us to take.
