I used it for ~10 weeks at 600mg/wk with Test Enanthate/Cyp at 750mg-1g/wk. Kept my apetite up, my endurance seemed far better than normal and I did notice an increase in vascularity. Oh--and my joints that were problematic felt a lot better while on the EQ, nothing else AAS-wise has ever helped with that (I haven't really had a chance to run deca yet). The most negative side IMO was an increase in anxiety, I have no idea why EQ caused that.
I think you should take a good dose if your gonna use it--600mg a week at least. That's just my opinion though.
