It’s being reported that Brock Lesnar has tested positive for the estrogen blocker Clomiphene, according to LA Times writer Lance Pugmire.

Jon Jones previously tested positive for Clomiphene and is common among combat athletes looking to increase testosterone while cycling off of steroids.

As we noted earlier this week and tonight, Brock Lesnar has now failed two USADA administered drug tests. Obviously, this substance has not been confirmed by USADA, UFC or the Lesnar camp, so take this with a grain of salt.
