Brock Lesnar stunned the world when it was announced that the former UFC and WWE Champion had failed a drug test.
The Beast Incarnate then managed to fail another test, his in competition one, on top of that, which was revealed last night.
Well, after days of rumour-mongering ever since he failed the first test, the substance that Lesnar was popped for may have been outed, and it should be very familiar to UFC fans who have been paying attention over the past week or so.

According to a report from Lance Pugmire of the Los Angeles Times, citing sources, Lesnar tested positive for Clomiphene, a prohibited substance on the USADA's banned list.
As Pugmire notes, Clomiphene is the very same substance that Jon Jones tested for in the run up to his fight against Daniel Cormier, which had to be scrapped with 'Bones' being replaced by Anderson Silva in a non-title match.
An estrogen blocker, Clomiphene can be used in two ways, to deal with the unwanted side effects of taking testosterone, and potentially also as a masking agent when coming off testosterone replacement therapy.
It is not the type of substance that can be taken without knowledge, which is a big hit to both Jones and Lesnar's claims that they were unaware or took tainted supplements.
Both Jones and Lesnar are facing a two-year suspension from the UFC. It remains to be seen if Lesnar will face any repercussions from the WWE for his failed tests.
