What is a normal free testosterone level?
The short answer
A typical US lab prints a normal free testosterone range for your sex: 0.1–6.4 pg/mL for women, 47–244 pg/mL for men. That range exists to catch disease, not to describe your best.
Nobody we follow has said what your free testosterone should be. It comes up on the shows, but never with a number.
What free testosterone measures
The testosterone riding free of proteins, ready to act on tissue.
Proteins hold most of your testosterone out of reach. The free portion often explains symptoms the total misses.
