proviron is almost always a good add to a test cycle.
- acts as a mild anti-a / anti-e to help reduce chances of gyno and bloat
- competes with test for binding to SHBG, so will tend to keep more injected test bioavailable (free)
the winny does sorta-kinda the same (plus alot more), perhaps not as effectively, so one way to do this would be proviron from the beginning, and reduce the dose when you start the winny.
