Fitness coach Jeff Nippard is taking a closer look at the timeless ‘natty or not’ debate. In a recent YouTube video on August 7, 2025, he discussed steroid use, citing history, common sense, and science to reveal the limits of what’s possible naturally.

“I’m diving straight into the dumpster fire, and I’m taking three tools with me: history, science, and common sense. Using those three tools, I’m going to give my final answer to the question: How big can you get without steroids?”

Nippard is a leading educator in the fitness space, having amassed a huge online following. With over 7.43 million YouTube subscribers, he unveils the science behind training , supplementation, and performance-enhancing drug use.
