Wow, he's genuinely off in the off-season. That's rare as fuck in this social media era. Respect.
Not "natty" though, but what the fuck does that even mean these days? Everybody's on something. Maybe he's on TRT + SARMS + peptides.
Edited to add: I've heard of at least one US doc who will prescribe 400mg/week testosterone as "TRT". This makes for very large and muscular "natties" who cruise on 400mg/week for life.
