I never bought his BS anyway. I have been in Gyms and have been an athlete my whole life. I have been around natural freaks of nature, roid heads, super athletes. I can ALWAYS tell a steroid body from a non one. It isn't just one thing, but more an overall aesthetic with multiple tells. The biggest being size with vascularity and thin skin.
When you have a natty genetic freak that trains like an animal you get this:
When you do certain gear, your skin thins and tightens around the muscle making you extremely vascular even when not working out for the pump. You see veins where you normally do not (Chest, Calves, shoulders).
