Paulo Costa was bothered by Azamat Murzakanov's comments about a 'secret juice' related to Russian fighters. Murzakanov stated that very soon people will learn what the secret is and what Russian fighters have that others don't. The post indicates that Costa took offense to these remarks, though his specific response is not detailed. The 'secret juice' reference appears to be Murzakanov's cryptic hint about some advantage or preparation method used by Russian fighters. The exchange adds another layer to the narrative building around their upcoming fight.
Paulo Costa has fired back at Azamat Murzakanov after the Russian light heavyweight made cryptic public comments about a so-called "secret juice" that Russian fighters possess over their opponents. The exchange surfaced on social media ahead of the pair's upcoming bout, adding an early antagonistic edge to the rivalry.

Costa, nicknamed "The Eraser," enters the fight carrying a 16-4 record and currently sits ranked thirteenth in the middleweight division. The 35-year-old Brazilian, who trains out of Team Borracha, is one of the more physically imposing fighters in the sport at six-foot-one with a 72-inch reach. He is a high-output striker, landing an impressive 6.26 significant strikes per minute at a 58 percent accuracy rate, making him one of the more dangerous hands in his weight class.
Murzakanov, who goes by "The Professional," holds a 16-1 record and is ranked twelfth in the light heavyweight division. The 37-year-old Russian, who fights out of K Dojo Warrior Tribe, is a southpaw standing five-foot-ten with a 71-inch reach. He lands 4.7 significant strikes per minute at 57 percent accuracy and adds a modest grappling dimension with 0.55 takedowns per fifteen minutes. It was Murzakanov who ignited the back-and-forth, stating publicly that people will soon discover what Russian fighters have that others do not — a remark Costa clearly did not take lightly.

Why it matters
- The verbal sparring raises the personal stakes heading into an already competitive matchup between two ranked fighters.
- A win for either man would represent meaningful movement in their respective divisional pictures.
- The contrasting styles — Costa's high-volume punching versus Murzakanov's southpaw pressure and takedown threat — set up a compelling style clash.
- The "secret juice" comment carries potential anti-doping undertones, which may fuel further tension in the lead-up to the fight.
