Going to get BW done for the first time since starting TRT.

While I'm there I feel I need to mention HCG to my doc, I'm guessing he's never heard of it. What should I site as my main reason for wanting it?

Honestly I've read a lot if talk about it and I'm still confused. Due to sides am I better off without it if I don't need it? Or does being on TRT mean I should be on HCG?
