@Cataceous, are those ranges for what is considered normal in general 2 standard deviations on each side of the mean? Meaning 23ng/dL would be approximately the 98th percentile?No, a cFTV (calculated free testosterone by Vermeulen) of 17.2 ng/dL is above average for healthy young men. Average for them is around 15 ng/dL. Or at least it was some decades back.
As I said above:
If you use the Vermeulen calculation then you can compare yourself to a range for healthy young men of about 70-230 pg/mL (7-23 ng/dL).
