I found this quite amusing. Despite Houlihan having been caught and banned by the AIU in 2021, the USADA has still been regularly PED testing Houlihan since that time and all the USADA testing has returned no positives.
Number of times the USADA has tested Houlihan per quarter:
Q1 2021: 3
Q2 2021: 6
Q3 2021: 6
Q4 2021: 0
Q1 2022: 4
Q2 2022: 9
Q3 2022: 3
Q4 2022: 0
So base on this, I certainly "believe" Jerry Schumacher when he says Houlihan is "clean". After all, the USADA drug testing works and they are not reclassifying positive tests as negatives, right? The AIU must be wrong with their laser like targetted testing of American athletes.
