I guys, I'm in the 4th week of PCT (nolva 20 mg and clomid 50 mg). last week , I had no libido but if I was encouraged by my girlfriend , my cock felt good! but now that my cock does not respond, I do not have erections and have to solve soon. I had thought of cialis or proviron . What do you recommend ? I have to resolve in a few days without affecting HPTA possibly ..
