I took two separate tests from two different labs.
One test I had to provide 10ml of saliva first thing in the morning.
The test results were basically that I have the testosterone of a 12 year old boy, or an 80yr old man.
I took another test where I was to provide 4ml of saliva at 9AM and another 4ml of saliva at 4pm. The saliva was to be frozen and shipped.
Again, same results.
