Bored Ape owners are dropping millions to watch their digital primates mutate. The NFT collection from the Bored Ape Chemistry Club is a collection of Mutant Serums that Bored Ape Yacht Club owners can use to alter the appearance of their apes. There are three tiers of Serum injections — M1, M2, and M3 (Mega Mutant). With just three viral serums left in the world, the M3 variant is more coveted than ever and selling for record-breaking prices, with the latest going for $5.8 million. All serums expire once they're used, making them all the more valuable.
