What punishment did mark mcgwire have after taking steroids?

Mark McGwire did not face any formal punishment for taking steroids, as he was never suspended or fined by Major League Baseball (MLB) during his career. He admitted to using performance-enhancing drugs in 2010, but by that time, he had already retired. The lack of a specific penalty was largely due to the absence of strict steroid regulations in MLB during the peak years of his career.
