Trace amount of same steroid metabolite found in Jon Jones’ UFC 232 VADA test results.
UFC vice president of athlete health and performance Jeff Novitzky told MMA Fighting that he’s not at all surprised that the M3 metabolite is still in Jones’ system and “pulsing” or showing up at different times. Novitzky said experts have theorized that the metabolite pops up in drug tests when Jones is cutting weight or doing heavy exercise, which could explain the weigh-in day abnormal reading. Like CSAC, USADA will not be taking any action against Jones for this instance, Novitzky said.
Novitzky said USADA has found another UFC fighter, whom he would not name, who is going through a similar “pulsing” situation with the M3 metabolite.
