What supplement does Shaq use?

I'm curious to know, what supplement does Shaquille O'Neal, the legendary basketball player, use to maintain his impressive physique and athletic performance? Is it a specific type of protein powder, a multivitamin, or perhaps a more unique, lesser-known supplement? With his size and strength, I'm sure many people would be interested in finding out what supplement regimen he follows to stay in peak condition. Could you provide any insights or information on what supplement Shaq uses?
