Let's assume that it was TB4 for the purposes of this argument.
The athlete could say that they looked at the WADA banned list in 2012: http://www.wada-ama.org/Documents/W...ed-list/2012/WADA_Prohibited_List_2012_EN.pdf and they checked the ASADA website and there was no mention of any type of Thymosin.
So is it the athlete's responsibility to know that TB-4, which they weren't told they were given, falls under the "as well as any other growth factor affecting muscle, tendon or ligament protein synthesis/degradation, vascularisation, energy utilization, regenerative capacity or fibre type switching; and other substances with similar chemical structure or similar biological effect(s)." clause?
Or are they supposed to know that Thymosin Beta 4 (which they weren't told they were given, falls under the clause S0 - "Any pharmacological substance which is not addressed by any of the subsequent sections of the List and with no current approval by any governmental regulatory health authority for human therapeutic use (e.g drugs under pre-clinical or clinical development or discontinued, designer drugs, veterinary medicines) is prohibited at all times.", whereas Thymosin A (which they were told they were given) is approved for medical use.
Read the first post in this. It'll make things clearer.
