you can run it however long you want, thats up to you but im not one that uses drugs like clomid, nolvadex, aromasin etc. any longer than you actually need tem
You vwm certainly do it, but if it were me id run a good test booster at the end of the cycle leading into pct then switch to Clomid. I'd see it being more effective without adapting or desensitizing to the Clomid
