The Nevada athletic commission tested Jon Jones on three separate occasions during December 2014. Two of these tests, both administered on December 4th, showed the presence of cocaine metabolites. What has received less discussion is that all three tests show abnormal levels of testosterone and/or epitestosterone.
All tests show his testosterone level being significantly below the normal margin. His T:E levels of .35 .29 and .19 raise flags, but it is the actual levels of hormone detected which raise more questions.
On what appears to be his first test of December 4th, Jones testosterone levels measured at 59ng/dL. The normal range is 300ng/dL to 1100ng/dL. His epitestosterone levels measured at 170ng/dL. The normal range for epitestosterone is similar to that of testosterone.
On what appears to be his second test of that day, his testosterone levels had risen significantly to 180ng/dL, which is much closer to normal. His epitestosterone levels had also risen to 610ng/dL, which is perfectly normal.
On December 18th his testosterone levels are still lower than normal, at 180ng/dL, but his epitesterone appears to be massively elevated, coming in at 2700ng/dL. This is a red flag. Epitestosterone is produced in parallel with testosterone, and in a normal, healthy individual every 1ng/dL of testosterone produces roughly 1ng/dL of epitestosterone. Natural variance means anything from 0.7x to 2x are pretty common. Jon Jones had roughly 15x more epitestosterone than testosterone
