Derrick Lewis
UFC heavyweight contender
Derrick Lewis is one of the UFC's most popular heavyweights, known as much for his candor as his knockout power. Ahead of UFC 324 he claimed on a podcast that the promotion had 'provided me with some great peptides' — prompting a public correction from UFC executive Jeff Novitzky, who said Lewis 'misspoke' and clarified that the UFC does not supply banned peptides, only third-party-certified compounds. The episode is a useful illustration of how loosely the word 'peptides' gets used in sport. Documented from MMA press.
