Los Angeles Times reported Lance Pugmire is reporting that Brock Lesnar’s positive drug test was for the same drug that Jon Jones failed for. Pugmire says that an official with knowledge of Lesnar’s test said that that the substance was clomiphene.
Clomiphene is an anti-estrogen blocker that is on the banned list. Clomiphene is commonly used as post-steroid cycle therapy and the drug is known to help stimulate testosterone production. The drug is said to be cheaper than TRT and has fewer side effects.
As noted earlier, Lesnar failed tests from his sample collected on June 28 and July 9, the test conducted on the day of his fight with Mark Hunt.
I'm told by an official with knowledge of Brock Lesnar's positive test that the substance is clomiphene, the same one found in @JonnyBones.
