Deontay Wilder: natty or not?
Likely natty "The Bronze Bomber" — WBC heavyweight champion, 2015 to 2020, and the hardest right hand in boxing
Short answer. Verdict: likely natty. At the peak physique on this page, Deontay Wilder is 6'7" (201 cm) and 212 lbs (96 kg) at roughly 10% body fat. That works out to an FFMI of 20.1, against the ~25 mark cited as the natural ceiling.
No official record settles this. What follows is opinion and analysis based on public numbers — how we judge.

Note. Fighting weight is a weigh-in-era figure and the body-fat number is an estimate. The verdict is opinion, and on this page it is an opinion in his favour. See the methodology page for how we judge.
Deontay Wilder is the rarest thing on this site: a heavyweight champion who reads clean on every measure we have.
He is 6’7” and fought most of his career around 215 lbs. For that height, that is thin. His FFMI is nowhere near the ceiling — it is nowhere near the ceiling for an ordinary gym lifter. He knocked people unconscious with leverage and timing, not mass.
The company he kept
The doping in Wilder’s story belongs to the other corner. Alexander Povetkin tested positive for meldonium before their 2016 fight, postponing it. Luis Ortiz failed a 2017 test for two diuretics, drugs that can mask other substances. Bermane Stiverne missed a test in 2017, which VADA reported and the WBC treated as equivalent to a failure.
Three opponents, three anti-doping problems, none of them his.
The Fury excuses
After losing to Tyson Fury in February 2020, Wilder claimed his water had been spiked, that his ring-walk costume was too heavy, and that Fury had scratched his ears. He offered no credible evidence and the claims were widely dismissed as excuses. It is a bad look and it is not a doping matter, in either direction.
Verdict
Likely-natty — no failed test, no allegation against him, and a build that requires no explanation. We give this verdict rarely, and a 215-lb man at 6’7” is exactly the case it exists for.
