It all sounds pretty legit to me, OP.
If you really have estrogen issues, just get some Nolva. You want fairly high E2 in your case, as it is good for collagen and all that.
And Dec11, I know some studies have show that nandrolone, EQ, etc decrease collage synthesis or otherwise do not help, but I have to question the validity (or relativity) of their findings.
It is going to take more than some rabbit studies to contradict the in-vivo experience of thousands of athletes.
The only AAS that I'm certain is NOT good for joints and connective tissue is Winstrol.
Even test has the potential to help, as it increases IGF-1 and E2.
