I haven't trained for mass in a long time, but for what it is worth, after pushing yourself for 4 weeks on a 5x5 for strength, then dfht for another 4 weeks, thats 2 straight months of pushing hard.
May be a good time to back off a little, drop your weights down for 2 weeks or so.
as far as the routine, it looks to me like there is a whole lot of volume, and overlap. for instance on day one you have 3 chest movements, the first of which is flat bench for 5x5. Day 2 you are starting with shoulder press 5x5. You will be hitting both chest and shoulders two days in a row (each of those movements works both). I would switch some of that up, but that is just my opinion.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
