Hormone levels/ Units of measurement

I’m aware that T-Mag readers are some of the more knowledgable members of the lifting community. So here is my question and I hope I list enough detail in order to receive an adequate response.
I recently had my testosterone levels checked. My results were on the low range of the “normal male subject”. I clocked in at 20.9 nmol/L. The average male is said to be found between 8 nmol/L to 38 nmol/L.


My questions are the following:

  • Are my levels of testosterone high enough to make decent amount of gains?
  • Why are levels of testosterone given in other units of measurement. And how do you convert it from nmol/L to X(unknown unit of measurement).
    Thanks for your time;)

Your number is not low, given the
reference values for the normal range
you provide.

Bill, do you have any idea on how to convert nmol/L to the American reference of measurement. (I think it is nanograms per decilitre or something). My testosterone usually hovers around the 4.5-5 nmol/L and I want to work out the conversion. Thanks

To convert nanomoles of testosterone
to nanograms, multiply by the molecular
weight of testosterone. I don’t have a Merck
Index handy, but I think it’s 288 (and if it’s not, that’s close enough.) So now you’d have
nanograms per liter. To convert this to nanograms per deciliter, divide by 10.
