For myself, I run Clomid for 2 weeks at 50mg/day. Then clomid 2 weeks at 25mg/day.. start to lower my AI dosing around the 2 week mark into pct.. off everything by 4 weeks.. I def. Do not recommend stopping AI "cold turkey." Drop dose down slowly over 2-3weeks. I'm planning on staying off cycle as long as I was on cycle.. that means, after my month of pct, I run NOTHING for (in this case) 16weeks.
