I hope you aren't running the dbol 10 weeks, lol. I hate using Nolva on cycle. I opt for arimidex or aromasin if necessary. Then I'll use nolva for PCT. There are some studies that show Nolva reduces IGF-1 levels....so, I don't use it on cycle and when I use if for PCT I also run some IGF-1. That's the best possible scenario.
