He's a vocal advocate for the need to take care of our minds and bodies and approach fitness for the right reasons.

But that hasn't always been a priority, it's a lesson Mark learned the hard way after abusing steroids, spiralling out of control and bringing himself back from the brink.

In this revealing conversation he gives a no holds barred insight into his darkest days and the reality of using steroids.

Mark is down to earth, engaging and genuine in telling it like it is. He's not afraid to shed an ugly light on the elephant in the room topic that many in the fitness industry shy away from. This episode also features a separate chat with world renowned endocrinologist, Professor Gary Wittert. He was kind enough to break down the facts about steroids and testosterone, answering many of the scientific questions that loom large.
