At the advice of War, I dropped my nolva and am just running .25 adex ED and Cabergoline.25 mg twice a week. Im on week 5 of my Test prop and NPP cycle. So far so good. If you think you're gyno prone you might want to try caber next time you cycle deca. I always get puffy nipps and have had lumps but if you get to them quick and aggressively they will go away.
HCG surely won't hurt, but I dont think you need it.
