I like to use Saliva test kits to test my "FREE" Testosterone levels & my new Products, they generally run around $30 including shipping (both ways) and test fees.

I have used ZRT labs in the past but this is one I found today on google;

Their are many saliva test kits to test many different hormones and other options.
