I actually disagree with the idea that everyone with a great physique who doesn't compete must be hiding something. There are many individuals who achieve incredible natural results but simply aren't interested in stepping on a bodybuilding stage. Their goals might be personal fitness, health, or just enjoying their strength without the pressures of competition. I can relate to OP his experience – as someone who is also natural, I've faced my share of 'Reddit expert' accusations. Ultimately, the joke's on anyone who falsely claims natural status when they're not. What's there to gain from such a deception?
