Ulisses Williams Jr.: natty or not?
Likely enhanced Musclemania world champion and Instagram's most famous "8-pack," claiming lifetime natural
Short answer. Verdict: likely enhanced. At the peak physique on this page, Ulisses Williams Jr. is 5'10" (177.5 cm) and 209 lbs (95 kg) at roughly 10% body fat. That works out to an FFMI of 27.3, 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)
| Peak physique | Musclemania world-champion era (2013), reported around 210 lbs |
|---|---|
| Height | 5'10" (177.5 cm) |
| Weight | 209 lbs (95 kg) |
| Body fat | ~10% |
| Started lifting | around age 19 |
| FFMI | 27.3 — ~25 is the cited natural ceiling |
Era by era (estimated)
| Era | Year | Age | Weight | Evidence | Body fat | FFMI |
|---|---|---|---|---|---|---|
| First competition wins | 2000 | 24 | 185 lbs (83.9 kg) | reported | ~8% | 24.7 |
| Musclemania world champion | 2013 | 37 | 209 lbs (95 kg) | reported | ~10% | 27.3 |
| Maintained form, pushing 50 | 2026 | 50 | 205 lbs (93 kg) | reported | ~10% | 26.7 |

Note. Ulisses Jr. has always said he is a lifetime natural, and no test, record, or admission contradicts him. Everything below is this site’s opinion from public numbers — estimates and reported figures, not measurements.
His denials are on the record and quoted above in full — he points at his Musclemania testing history and jokes that two decades of imaginary juice would owe him a refund. He started lifting at 19, won novice shows by 2000, and has outworked essentially everyone in his industry for 25 years. All of that is real.
The math
So are the numbers. His champion-era stats — about 210 lbs (95 kg) at 5’10” (177.5 cm), visibly shredded — compute at our conservative 10% read to 188 lbs (85.5 kg) fat-free: FFMI 27.3, and higher at his claimed leanness. That is two-plus points past the drug-free ceiling, in the over-26-and-lean band the method treats as its strongest single physique signal. And the timeline compounds it: he carries essentially the same shredded mass today, pushing 50, as he did at 37 — the age-immunity pattern natural physiology doesn’t produce. Musclemania’s natural credential rests on polygraph-and- event-day screening, which career-length use routinely survives; a general limitation, not an accusation about any test of his.
What cuts the other way
Sponsor-sheet numbers inflate; shave them and he trends toward the ceiling instead of past it. His symmetry-first, moderate-size aesthetic is at least the right SHAPE for a natural claim — this is not a mass monster — and his consistency, from diet to denials, has never wavered.
Verdict
Likely-enhanced — as opinion, on the same reasoning as every physique in this band: sustained over-ceiling math plus decade-scale age-immunity outweighs polygraph-grade testing. The tripwire is the same standing offer: one verified DEXA-grade body composition at his claimed stats would flip this page into an apology and a genetics tribute.
In their words
“If I was juicing for these past 15 years or so, something would have came up.”
“I'm around 200lbs. If I've been juicing for nearly 20 years then I need my money back. I must have been wasting my money for years!”
Common questions
Is Ulisses Williams Jr. natty or on steroids?

Has Ulisses Williams Jr. ever failed a drug test or admitted to using PEDs?
Nothing of the sort turned up in the sources on this page. Had it, the verdict would read confirmed instead of likely enhanced.
