Here is my concern about running it with eq. Since eq takes so long to get into your system, I have always ran it for 12 wks. I'm going to run the var 3 wks past my last shot of test/eq or primo, but I don't want to be on for 15 wks. This is why I'm leaning towards primo. I feel that I would get more out of it during a 10 wk period than eq. Makes sense, or no??
