I don't have an official T level measurement from before HRT, but I have very good reasons to suspect that my T levels were abnormally low. Such as, not really having a lot of body hair, having a rather pear-shaped body that still managed to have a waist-hip ratio in the "healthy" range of the mid-0.8's despite being 270 lbs, pretty much no sex drive whatsoever, very low muscle mass, and a general lack of defining masculine features. And I also do know that when I started HRT, my T levels were down even below the female "normal" range after only 3 months on the absolute minimum dose of Spiro. So yeah, methinks I was pretty testosterone-deficient way before I started HRT. I don't have official levels, but I'm guessing I was at the very lower end of the "normal" male range before starting, if not lower.
