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

Paulo Costa has taken issue with recent comments made by Azamat Murzakanov about a "secret juice." Murzakanov stated that people will soon discover what fighters from Russia possess as their secret. The comment appears to reference some competitive advantage or training method used by Russian fighters. Costa's reaction suggests he found the remarks provocative or disrespectful. The two fighters are scheduled to meet at UFC 327 this weekend in a light heavyweight bout.
