Logan Paul's energy drink company Prime Hydration slapped Ryan Garcia with a defamation lawsuit after the boxer blamed his positive drug test on the drink. 

The former YouTuber claimed his company was 'under attack' by false narratives being perpetuated by the 25-year-old. 

'Today we begin to hold those accountable who've damaged our brand for attention while we correct the narrative,' Paul wrote on Instagram Thursday, alongside an image of the lawsuit filed in a Texas court.

'We're here to stay and will continue to change the world of hydration with bold flavors and creative innovation,' he added. 

Garcia has been on several social media rants after testing positive for performance enhancing drugs ahead of his shocking upset victory over Devin Haney back in April.

The controversial athlete claimed the drink will 'kill your guys's (sic) brains,' 'mess up your guys's (sic) liver,' and 'hurt you big time.'

He even went as far as to claim, 'I drank Prime and I tested positive for ostarine.'

Prime is suing Garcia for defamation, trade libel, violations of Lanham Act, unfair competition and unjust enrichment. 

The boxer had a bizarre reaction after it was reported Thursday morning that both his A and B samples, which were collected before his fight with Haney, had tested positive for the banned substance.

'Let's go we positive positive vibes bruh Yess so happy,' he tweeted.

'I F***ING LOVE STEROIDS,' he wrote in a follow up post. 'I don't care I'll never make money again with boxing your loss not mine for setting me up lol joke on yall.' 

In the aftermath of his first sample coming back positive earlier this month, Garcia said that the results were false and requested by letter that his B sample get tested.

Now, the result of the fight would be up to the New York State Athletic Commission to decide how to proceed - with Haney personally calling for the fight to be called a disqualification win.

Garcia previously maintained his innocence and said 'everybody knows that I don't cheat.' 

He's also suggested that his support for Donald Trump may have made him a target for increased scrutiny in testing.

'Hmm I'm seen with trump and now I'm positive for steroids this is a straight attack Crazy,' Garcia tweeted on May 1.
