Has anyone here ever had any problem with impotence from using steroids and if so for how long?
I don't know of anyone that has had that problem unless they were putting the deca to themselves without test.
My last cycle was 750mgs/week of test-e and 500mgs/week of tren-e and I was needing to get busy 2-3 times a day.
Androgens are what stimulate the sex organs. The more androgenic steroids like DHT, Proviron or 4AD are a real help.
Deca is not very androgenic, so when it binds to the androgen receptors in your penis they aren't as stimulated as they would be with a strong androgen attached.
I haven't tried deca but I did try nandrosol which is similar. I didn't have any problems that I can remember. In fact things worked fairly well. I did start mixing it 50/50 with androsol since I liked the androgenic effect.
I think as long as you don't chemically castrate yourself with something that has progesterone or estrogen in it you'll be okay.
