Paulo Costa reacts to Azamat Murzakanov's 'secret juice' comments

Paulo Costa has taken issue with comments made by his upcoming opponent Azamat Murzakanov about a supposed "secret juice." Murzakanov stated that "very soon we will show what the secret is" and that people will soon find out "what people from Russia have." The Russian fighter's cryptic remarks appear to have gotten under Costa's skin ahead of their scheduled bout. Costa, known for his own history with USADA issues, seems bothered by the insinuation. The exchange adds another layer of tension to their upcoming matchup at UFC 327 this weekend.
