Roelly Winklaar: natty or not?

Likely enhanced The Beast — IFBB open-class star, third at the 2018 Olympia, arms cited among the best ever

Short answer. Verdict: likely enhanced. At the peak physique on this page, Roelly Winklaar is 5'6" (168 cm) and 285 lbs (129.3 kg) at roughly 5% body fat. That works out to an FFMI of 44.3, 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.

The numbers (estimated)

Note. Stage weight is his listed competition figure; body fat is a contest-shape estimate. The verdict is opinion. See the methodology page for how we judge.

The archive’s earliest dated image of him is the Generation Iron premiere in Los Angeles on 18 September 2013 — mid-career, in a shirt. The real “before” he published himself: an Instagram photo he captioned “Back when I was 18 and living in the Netherlands. I was a soccer player then”, slim and lanky, with no weight attached. That caption is the only baseline his record holds: a number-free “before” from the man himself.

The numbers

Generation Iron lists him at 5’6” (168 cm) and a competition weight of 285 lbs (129 kg), carried through an open-class career that peaked with third place at the 2018 Mr. Olympia. Stage-lean at that size, the FFMI computes around 44 — nineteen points past the drug-free ceiling, on a man who only got serious about the sport after a near-fatal car crash in adulthood. There is no natural arithmetic that reaches this row from any baseline, let alone from a lanky soccer player.

About the reported admission

In January 2026, Muscle & Fitness reported that Winklaar described his first steroid cycle on the Menace Podcast. We could not independently read that page to quote his words — it refuses our checks — so this site does not treat the admission as verified, and the verdict stays one step short of confirmed until we can quote him directly or another outlet carries the audio’s words. That is a rule about our sourcing, not a doubt about the physique.

The concession

The genetics are extraordinary — the arms in particular are cited as among the best the sport has ever seen — and by the standards of his division he was famous for conditioning and work ethic, not shortcuts. As on every open-class page, the drugs explain the era, not the man.

Verdict

Likely-enhanced — an FFMI in the mid-40s in an untested open division decides the opinion on its own. The moment his podcast account can be quoted from a source we can read, this page moves to confirmed in his own words.
