If you are gong to use nolva you need to following the correct dosage protocol of 20/20/10/10. Or use an OTC pct such as reboot or a 6 bromo based AI and then use a dda based test booster. For OTC pct I would run a 6 week pct. using the last two weeks to tapper you AI down, use the test booster for 6 weeks. Hope that helps.
