==== CAS did not need to conclude that adulteration occurred, but only that the Athlete’s theory was not more probable than alternative scenarios. ====

Critical factors:
* Container 2 (the jar with very low levels of GW1516) was not the Athlete’s, but shipped to the athlete’s father’s veterinary address, then forwarded to the athlete — all undisclosed until CAS.
* Testimony from the Athlete and family was contradictory, internally inconsistent, and lacked clarity on crucial dates, access to jars, and who handled them.
* WhatsApp messages between Athlete’s father and coach Phiri on 10 August 2023 showed both men discussing GW1516’s 40-day excretion window, undermining claims they did not know about the substance.
* Lausanne Laboratory demonstrated adulteration was easily achievable, even without advanced tools.
* Athlete’s father, a licensed veterinarian, had ability to access controlled substances.
* GW1516 is readily purchasable online in pure form.

CAS conclusion:
➡ Athlete failed to establish his version was the most likely scenario.
