Fine bro, yep I personally would, proviron is very understated it doesnt have a muscle building effect but to me and in my view it has some rather good qualities and its does harden you up, it will work well with your winny, so yes if you have enough use it throughout mate, its only gonna help you.
It may also be advisable to run your proviron for 4 weeks post cycle bro, thats another thing that I do, it helps keep your androgen level up and aids in post cycle recovery.
