Derekh, If I were to change anything, I would have used a little more test. EQ is a decent but VERY MILD drug (from what I felt at least). Sides were really limited to oily skin so if you are looking to avoid sides EQ would be a good choice. Definitely a good stack for beginners imo. I noticed while on EQ, vascularity, better cardio but not much more than that. Since I ran it in addition to tbol, it would be hard for me to tell you which compound gave me more mass building effect although when I dropped the tbol, (which I loved) strength went down a bit and so did weight (2-3 pds).
I never really had problems with joints so it's hard for me to tell if the compound would improve such a thing but nothing got worse so I am guessing that would not be an issue. Also, EQ is not a dry drug so joint pain should not be an issue unless you stack it with ex, winstrol etc.
Hope that covers what you were asking but don't hesitate if you got more questions
