Jon Jones test results lead to speculation about performance enhancing drugs

The results of Jon Jones' failed drugs test would appear to suggest that Jones wasn't just using cocaine.

The UFC Light Heavyweight champion was checked into rehab earlier this week after it emerged that a random drugs test found him positive for cocaine.

However, those same results now are being scrutinised by some medical professionals, as the results would indicate that Jones was using performance enhancing drugs.

What's wrong with the tests?

The issue that some have flagged with the tests is Jones' T/E results (testosterone to epitestosterone levels) have an extremely low ratio, one that would indicate a rare medical condition or someone trying to mask PED usage.

The usual ratio for an adult male is expected to be 1:1 and with an athlete like Jones many would expect it to be higher than that and Nevada State Athletic Commission rules even permit up to 6:1.

However, Jones' tests came back .29 and .35 and a third test returned .19 which is unusually low for a male, especially one in Jones' physical prime.

MMAJunkie.com spoke to two professionals, one an anti-doping specialist and the other an endocrinlogist (hormone specialist), and both said that Jones' results would necessitate further investigation.

"I would go further and ask for a carbon isotope ratio (CIR_ test. That would tell you what’s really going on.” Said Don Catlin, the anti-doping specialist.

A CIR test is an expensive test that is usually reserved for those challenging positive blood tests, but it's main purpose is to track synthetic testosterone usage in the body.

Will the UFC request further tests or punish Jones?

So far, other than their statement about Jones entering rehab, the UFC has been silent on the matter of Jones' drug test failure.

However, that doesn't mean they haven't come under increased scrutiny in the past couple of days with many criticising the decision to let Jones fight after a failed test and some pointing out the axing of their drugs programme could be something to do with it.

Many expect to see Jones suffer some form of punishment, especially those who have been suspended, or even fired, for marijuana usage but the UFC has been oddly quiet.

Perhaps it's because Jones is arguably their biggest star and he's even ranked as the number one pound-for-pound fighter in the UFC. As such they're airing on the side of caution but at the moment, thing don't look great for the UFC.

With the pressure to investigate further and fighters speaking against Jones' decision, the UFC is either going to have to punish it's biggest star or act like cocaine is the only problem in this situation.

Either way - people want answers and until they get them it's going to be a whirlwind for the UFC.
