Masteron or proviron is a must add to any cycle in my opinion . You will not see the physical effects of mast until you're down to 10%ish, however the way it binds and frees up test is HUGE. It's a bang for your buck compound with test, run little less test and have more free test? Plus the positive sexual effects . And the mood enhancement....
As far as FOR a bulk, ehh.... I'm on a npp/test bulk now, with MAST. It's not going to help with the actual bulk, but all those other positives. I won't run a cycle without masteron or proviron.
We're running the same cycle (I'm using deca). Totally agree on Mast. Lots of benefits and synergies but as far as building muscle...meh.
