The op seems to be switching out primo for eq, curious why, doesn't primo have anti effects? How do the rest of the affects and fullnes or muscle quality compare? Strength etc? I took primo at too high a dose, like 500 with 750 or more of test and felt like I was on nothing, that was before resized how it affects estrogen and inthink I've become someone who dumps estrogen or it naturally doesn't convert as much etc. I ask for future cycles. For summer if I was running higher test like a gram would 300-400 primo kill my sex drive, would it have any anabolic affect? I don't know if it's bound or what but test doesn't work like it used to for me. Even running broke twice a week makes a huge difference in high test. So how does primo compare to test and to high dose test? Thanks
