Man, sounds like your body has not cooperated with you. I wonder why this is, that you could develop tendon issues in so many different areas?? I could see getting some tennis elbow or shoulder problems after lifting heavy for a few months, but everywhere!? I wonder if this hasn't been a hormonal problem, either from the low test, or an issue with lower estrogen. This is just a shot in the dark, but it just seems like it's something more than the common causes of tendinitis, which is usually from over use. Makes me wonder how HRT alone would effect you. Maybe getting a healthy amount of male hormone is what you need to feel better.
Anyway, yes, EQ is a great compound. I prefer it over deca, for myself. If I ever use nandralone, I prefer NPP. I don't get the progesterone build up that I've expereienced with long esters. I'm throwing this out there, as it might be something worth looking into, in the future.
You're cycle looks good. Only things I would watch are not to take too much AI. You want to have some in the cycle, but over doing adex can really dry the joints out, and probably cause you some pain. Also, I expect that you will be fine running lower test that EQ, at these doses, but if you find that your sex drive starts to drop, you might want to increase test to 400-500mg
If you ever decide that you want to do a cutting cycle, whatever you do, stay away from winstrol. It dries the joints and connective tissues out, badly. Something like masteron would be much better. Or var, which will also up regulate collagen production.
Last, I'll add that a long term run of GH would be beneficial to repair. Adding it into your cycle would only help, even at a smaller dose, like 2iu 5x wk
