I’d agree. The people I know who can reasonably simply be a “hybrid” are those who use various anabolic steroids, SARMs, and peptides, the latter two bring more interesting for this case as various ones target, say, joint damage and help repair them

Based on a google image search I think that's a safe assumption. Still impressive though.

I know a bunch of triathletes who look like that despite not using PEDs. They do, however, treat their bodies like temples and have the most rigorous diets I've ever seen.
