The short answer

Rogan claims normal adult male testosterone levels range roughly 300-800 ng/dL, and that Vitor Belfort tested at approximately 1,475 during his UFC testosterone-replacement-therapy run. Clinical references place the normal range for adult male serum testosterone at approximately 300 to 1,000 ng/dL, somewhat broader than the 300 to 800 ng/dL range Rogan cites but in the same general ballpark, with levels below 300 ng/dL generally used as a threshold for hypogonadism diagnosis.

What the evidence says 01 / RECORD

Clinical references place the normal range for adult male serum testosterone at approximately 300 to 1,000 ng/dL, somewhat broader than the 300 to 800 ng/dL range Rogan cites but in the same general ballpark, with levels below 300 ng/dL generally used as a threshold for hypogonadism diagnosis. Widely circulated mixed-martial-arts reporting from 2014, stemming from a Nevada State Athletic Commission-ordered blood test that Vitor Belfort released himself, put his testosterone level at 1,472 ng/dL during his TRT regimen, well above the normal range, a figure close to but not identical with the 1,475 Rogan states. That specific test-result figure originates from sports-press coverage (ESPN, Fox Sports, Yahoo Sports, and MMA trade outlets) rather than from a peer-reviewed, medical, or wire-service source, so it could not be independently confirmed against a tier-1 or tier-2 allowlisted publication. The broader claim that Belfort's TRT-era levels were far above the normal physiological range is consistent with what was publicly reported at the time, but the exact figure of 1,475 ng/dL is not corroborated in an authoritative source and should be treated as approximate.

Correction
· Unpublished pending quote repair: source transcript ASR garble. a low 300, a high 800; Vitor was like 1475
· ASR spelled the testosterone figures as words ('a low three a high eight eight hundred'); restored to numerals 'a low 300 a high 800' and dropped the stuttered duplicate 'eight'.
