Have you tried saw palmetto? One of the only over the counter sups that may help.
How old are you? If you are in your late 30s on, you may want to see a doctor, you don't have to tell them you are on AAS, they will just think you are getting natural sides to turning older.
I went to the Quack a few years ago. Told him that I was getting up to take a leak 3 or 4 times a night, plus I was leaking sperm when I was taking a shit. He suspected prostrate problems. Did the PSA blood test, which was fine. So no cancer but more than likely enlarged. So put me on Flomax. Ok...but he didn't mention the fact that in some guys it stops us from ejaculating. I have a rather, um..active and colorful sex life so my partners were WTF...don't you like me anymore...as there were no more money shots. LOL
Went back to the Sawbones and he put me on something else...not at home so I can't remember what it is, but it works just as well and doesn't stop the tin soldier from showering the ladies.
