It will shut you down. You NEED to do PCT. I just got off an Anavar only cycle 50mg ED for 7 weeks. I am definatly shut down, low energy level, no libido, plus my nuts have shrunk just a little bit. I'm currently taking Clomid 50mg / Nolva 20mg ED for a couple weeks. I was also thinking of adding 500iu of HCG 4x a week (2000iu a week total) to help regain testicular size.
