PCS is more of a test booster, 6 bromo is an aromatase inhibitor. They aren't really the same at all. Probably don't use the 6 bromo, estrogen will already be low after epi. PCS won't hurt, but it's not going to do a lot compared to what the SERM will do. If you want to run it I'd wait till week 3 but you can do it however you want.
