no, they need to prove that they attempted to take tb4, and that thats what was ordered.
if they have evidence that tb4 was ordered by dank through charter, charter went to china to get it from a factory that makes tb4 and no other thymosin, charter went to alavi and then dank picked it up from alavi - id say thats more than enough to prove that the club at least attempted to administer banned drugs...
the hole in that would be if essendon could turn around and say, actually they got x instead.... which they cant as they dont know what they were given!
