Dr said "You have facial hair and muscle - your test levels will be normal". When I got the results they said I was within the normal range/ It came back as 20.9 ng/L , which if I am not mistaken ng/dL would be 10x that number, so 209 ng/L. Is this considered low in the TRP spectrum?

I've drastically cut back masturbation (1x a week), started taking contrasting showers and eat very healthy with a high protein/fat diet. I have been seeing significant progress muscle wise as i've gained 25lb last 5 months (6'0, 175lb, 8-9% BF). So is this all in my head or should i consider testosterone replacement therapy?
