The elephant in the room:This is a straw man. The claim is just that a shop they shop at sells coke. More evidence is needed before it can be inferred that Essendon bought any of it.
Neither Dank, nor Alavi, nor Charter can produce an invoice for Thymomdylin that would cover the alibi. So if ASADA can prove they bought in TB4 (they can), it says Thymosin on the consent forms, and Dank has even admitted in an interview he used TB4, that's getting very close to “comfortable satisfaction''.
