I am a newbie. I just ordered 1 50ML 20Mg/mL of Tamoxifen Citrate (Nolvadex). I was wanting to take 10 to 20Mg a day during a cycle of Prop/Fina. I am confused. The vial I ordered from ARR is Tamox 1 50mL 20mg/mL. How many doses would this amount up to. Sorry for being stupid, just new at this. How is this administered? How many CC's do you draw from the syringe? Thanks for your help.
