Well, as a lover of eq, I guess I can comment on this since I have ran it through 4 cycles. It's not related to deca, but it's kind of like a weaker test in strength gains, and of course, it takes weeks to see the results (1,4-androstadiene-3-one,17b-ol ). I got extremely horny on it, which is always great. It will increase your red blood count so watch your bp. Also, I tend to get puffy nip syndrome from it occassionally, but it usually left a few months after running the cycle. A lot of guys run test and eq together - you grow big on the test and eq will give you noticeable hardness and vascularity. Sides for some include paranoia, sleeplessness and acne. I think most who run any steroid will encounter the last two, which I did everytime on eq. I personally love eq - it's a great drug for cutting and it's great for cardio. There's a pretty even divide here on the board about eq - some love it - some hate it. I'd personally give it a 8 on scale of 1-10.
