EQ is fine alone. Well, it is for me anyway.
A good EQ based cycle is:
EQ 12-14wk 400-500mg/wk
Winstrol last 4-6 weeks @ 50mg/day
This was my first cycle I put on 17lbs and kept most of it. I was very happy with the results.
I'm running 400mg EQ and 500mg test now and my sex drive isn't much better then just running EQ. First few weeks on EQ only used to increase my sex drive, but then in the later weeks seemed to taper off. If you add winstrol you could most definitely see a screwed up sex drive. I'd only run it for 3-4weeks towards the end as the full 6 weeks gives my willy some issues.
