What I was saying was wait an additional week to start your pct. proviron can definitely help but I don't think 25 is enough but I'm not an expert, 50 sounds more like the going rate. And as for the arimidex In pct, if you are dead set on running nolva clomid, I would run nolva like 20mg for 4 weeks, 10 mg for another 2 for 6 weeks total. But there are better options, and I would stop the arimidex a few weeks prior to the end of the nolva, so the nolva is still present to prevent rebound. What are your goals? Performance? Size?
