Paulo Costa was recently bombarded by USADA agents and woken up at 5 a.m. four times in the past three weeks for drug testing.'Borrachinha' boasts one of the most impressive physiques in the UFC. The Brazilian has also created a new gimmick around his "secret juice." He has attributed his enormous size and strength to this secret juice. But it's fairly obvious that 'Borrachinha' is joking.Whether or not Costa is joking seems to have no bearing on how much USADA has been testing the middleweight. According to 'Borrachinha', the anti-doping agency has woken him up two consecutive days in a row at 5 a.m. to collect urine samples.Paulo Costa took to Twitter to complain about being tested at such an unreasonable hour:"I cant believe USADA IS HERE at 5 am again!!!! It’s unbelievable"Paulo Costa ( Borrachinha )@BorrachinhaMMAI cAnt believe USADA IS HERE at 5 am again!!!! It’s unbelievable5171137I cAnt believe USADA IS HERE at 5 am again!!!!

The fight is scheduled to take place in February 2023. This means that 'Borrachinha' has mere months left with the UFC before becoming a free agent.Yesterday, the Brazilian took to Twitter to announce that when his "miserable" UFC contract expires, he will enter the world of boxing."My miserable contract with the UFC was up in a few short months. Will expire in time.
