300g/wk should be enough for the therapeutic benefit to your joints. You can some test if you want, but I'm not sure it's really in line with your goals? If you don't want all the size/cut I'm not even sure AAS is needed for your goals... At week 5 the deca should just really begin to be kicking in. So as far as deca dick you're not necessarily out of the woods yet, though the lower dose and the fact you've seen no evidence yet (or, I'm guessing, from the previous tren) may mean it just won't happen for you. I'm curious: are you taking any ancillaries right now? How long did you intend this deca cycle to last? I take it you have a good pct plan lined up?
