Tyson Fury: natty or not?
Confirmed "The Gypsy King" — beat Klitschko, beat Wilder, and served a backdated two-year doping ban
Short answer. Verdict: confirmed. At the peak physique on this page, Tyson Fury is 6'9" (206 cm) and 276 lbs (125 kg) at roughly 20% body fat. That works out to an FFMI of 22.0, against the ~25 mark cited as the natural ceiling.

FFMI over time (estimated)
FFMI per era (values in the table above). Hover a point for details.
Note. Fighting weight is a weigh-in figure; the body-fat number is an estimate. The verdict is not — it rests on a UKAD case that ended in a two-year ineligibility period. See the methodology page for how we judge.
Confirmed — a two-year ineligibility period is a doping sanction, whatever the negotiated route to it.
What he said
The backdating is the part people argue about. It meant the ban expired the day it was announced, so he served no additional time. That is a fact about process, not about the sample.
The numbers
At 6’9” and a fighting weight around 270 lbs, his FFMI is unremarkable — he is a very tall man carrying real body fat, and he has never pretended otherwise. His career includes a well-documented period out of the ring with depression and weight gain, and a comeback. None of that shows in an index.
He also failed a test for cocaine in September 2016, which he attributed to depression rather than performance — a recreational finding, not a performance one, and recorded here only so the page is complete.
Verdict
Confirmed — a nandrolone finding resolved as a two-year ineligibility. He has never accepted the substance of it, and the sanction stands regardless.
In their words
“Hughie and I have maintained our innocence from day one and we're now happy that it has finally been settled with UKAD.”
