Here's a copy of the prohibited lists for each year for anyone interested.
TB4 was explicitly added in 2018. It wasn't on any list before that.
It was however, without being named, still banned under the generic clauses in the S2 'Growth Factor' section or S0 'Not approved for human use' section, take your pick. This is why the website said you need to contact ASADA when it doesn't find an exact match. The lawyers knew this, that's why they didn't fight it, the fight was over whether TB4 was injected or not.
