But this happened after the first Cormier fight.
The first fight with Cormier was Jones first time under USADA. In one of those tests, his Testosterone levels came back at 59 ng/dl. That means his body was virtually producing no testosterone. It's average for a 10 year old boy and about 1 tenth of the average levels for a guy Jones age. But the drug test came back negative. It was put down to it being a dip due to excessive training, which is complete nonsense. This is why USADA went after him so hard. They knew, but had to publicly come up with BS reasons why his levels were so low. The only exercise you could do to make your levels that low is to repeatedly punch yourself in the nuts until they no longer work. The reality is his testicles stopped producing testosterone which happens due to the use of AAS. Interestingly one of the medications used to get your body to start producing testosterone again after it's shutdown from steroid use is called Cloimd. And guess what Jones has just served a suspension for? That's right - Clomid.
You have to be crazy naive to think anything other than Jones is a long term PED user.
