Proviron for me is like test, it's always in there no matter what. It's just something that helps me with a lot of sides and keeps me pretty hard. I hadn't planned on running masteron initially, but I ended up with an extra bottle or 2 and figured I'd throw it in there for shits and giggles. The combo together had me hard as nails. I was lean at the end of the cycle, but once the masteron was added, it seemed like my cuts were showing a lot more and my muscles looked like they were all cur from a rock
