The only things that will affect your sex drive negatively will be 19-nor products (deca & tren), coming off - no PCT (crashed) or excessive AI use.
Everything else seems to improve sex drive - more or less...
These are things that vary on an individual basis. For example, tren has no effect on my sex drive, while it kills libido in others. You just have to learn your body and what works well for you and your intended purpose
I have ran avar 40-80mg and had no issues... made me feel great. Tbol was 40-50mg and again no issues. I actually ran tbol alone to gain a better understanding of results (no test).
