The day before the fight, during the official UFC 187 weight-ins, Weidman accused Belfort of cheating saying "I left him alone with this all drug testing, but then we just found out during camp he had a 1200 testosterone score. I'm 10 years younger than him, he's got a way higher testosterone level. This guy is still cheating and I'm gonna make him pay for it tomorrow night." [source]
