Israel Adesanya: natty or not?
Uncertain "The Last Stylebender" — two-time UFC middleweight champion
Short answer. Verdict: uncertain. At the peak physique on this page, Israel Adesanya is 6'4" (193 cm) and 185 lbs (84 kg) at roughly 8% body fat. That works out to an FFMI of 20.0, 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 the division figure; the body-fat number is an estimate. The verdict below is a statement of what we do not know. See the methodology page for how we judge.
Israel Adesanya is 6’4” and fights at 185 lbs. By the numbers this site uses, he is one of the least suspicious athletes on it: tall, lean, and light for his height. Nothing in his FFMI comes near the ceiling.
The gynecomastia question
This is worth explaining because it is the one physical sign people treat as a smoking gun. Gynecomastia — breast tissue growth in men — is a known consequence of anabolic steroid use, because excess testosterone converts to estrogen. It is also caused by puberty, obesity, several prescription drugs, thyroid and liver conditions, and in some accounts cannabis. It is a real signal with a long list of innocent causes.
On its own it proves nothing. What would settle it is a test, and he competes under a programme that tests with no notice, year round, anywhere in the world. No adverse finding is on his record.
Verdict
Uncertain — one visible sign with many possible causes, against a clean record in a tested sport and body composition that raises no question at all. We are not going to convert a photograph into a verdict.
