A free testosterone level of 29.9 pg/mL in adult men is extremely high—likely above the 99th percentile, especially in natural populations.
Approximate Free Testosterone Percentiles (pg/mL):
These are based on population studies using equilibrium dialysis (the gold standard) or analog immunoassays. Ranges vary slightly by age and lab, but here’s a generalized estimate for healthy adult males (ages 20–40):

Percentile | Free T (pg/mL) |
5th | ~5–6 pg/mL |
25th | ~10 pg/mL |
50th (median) | ~13–15 pg/mL |
75th | ~18–20 pg/mL |
90th | ~22–24 pg/mL |
95th | ~25–26 pg/mL |
99th | ~28–29 pg/mL |
You (29.9 pg/mL) | >99th percentile |

- 29.9 pg/mL = above 99th percentile in the general population.
- It is very rare for a natural male to reach this level.
- Strongly suggests exogenous testosterone use (e.g. TRT or steroids).
