Be honest. My doc has known for years. The only issue I’ve ever had with telling him is that he put it in my notes or record “rather” and it threw a red flag when I was getting life insurance. They didn’t like that. When questioned, I just said it wasn’t steroids, and I told the doc it was a pro hormone I got from GNC or a supplement store. It worked thank goodness. Lol. Moving forward bloods checked out fine. Good to go. I Hope this helps.
