Liver King Accused of Violating ‘Blood‑Signed’ Deal He Allegedly Demanded
The controversial fitness personality known as Liver King is back in court—this time over a men’s supplement—and the case features a bizarre centerpiece: an agreement that was reportedly signed in blood.
According to a complaint filed by fellow health influencer Brad Kearns, discussions with Brian Johnson (aka Liver King) focused on a men’s product dubbed “Male Optimization Formula with Organs,” or MOFO. As Kearns tells it, the pair memorialized their understanding on a simple one‑page document. At Johnson’s urging, both parties are said to have marked the paper with their own blood to seal the deal.
In a formal response, Johnson’s legal team disputes much of Kearns’s account. They contend there was never a proper product pitch from Kearns and reject the claim that Johnson or his companies had any interest in the name “MOFO.” Yet the response does not contest the strangest detail: it acknowledges the existence of an agreement bearing blood markings.
For all the theatrics, the crimson flourish doesn’t give the document special power. Courts have previously found that contracts written with or marked by blood aren’t inherently binding and do not gain legal standing merely by virtue of the medium. At best, such gestures are symbolic—dramatic, sure, but not determinative.
Kearns maintains that the MOFO concept and name were central to the collaboration he believed the two had struck. The defense counters that no actionable partnership ever took shape and that any overlapping product names are incidental. The dispute, while undeniably petty in tone, will likely hinge on the same fundamentals that govern every business fight: what the parties actually agreed to, what consideration changed hands, and whether any obligations were breached.
The skirmish arrives amid broader legal turbulence for Johnson. He has already been hit with a class action from customers who allege they were misled about the efficacy of “ancestral” living and the origins of his physique following revelations about steroid use. Those separate claims, coupled with this latest quarrel over a supplement and a blood‑marked document, paint a portrait of an influencer empire that leans heavily on spectacle—and sometimes ends up litigating the aftermath.
Whether the court views the one‑page agreement as enforceable will come down to the usual contract basics, not the method of signature. And if nothing else, the episode serves as a reminder: in business, substance beats stunts—ink works just fine.
