Hey, my question is about proviron during only turinabol cycle. I'm on 40mg turinabol ED for 5 weeks and i will PCT after that, but outside of PCT what if i use proviron with turinabol during cycle?does it bring any harm? I'm on first week and i have no erectile problem.Should i start to use proviron now or i observe myself and if erectile problem starts then start to use it? Thanks for reading.
