Best complimentary/synergistic anabolic to add to T?

[Beef_Supreme]

Seeking opinions on what you believe to be the best anabolic "add-on" for TRT or TRT+
Right now I've got myself at 205mg/wk test c. along with 750iu HCG, I may increase test a bit more in the coming months, we'll see.
I have added in 100mg/wk NPP, mostly to try out the supposed joint lubrication benefits but I'm kinda meh over it. I have no problem dropping it to replace with something else.
I pin both everyday.
Thought I'd ask for some opinions. I think the go to would be masteron, and I'd be fine giving that a shot. I'm still slowly
bringing down my body fat, and am currently at 21% (I was becoming quite the fatass) so some of it's benefits I don't think would apply to me
until I get myself down into the mid teens. If I'm wrong please correct me. I'm in a pretty good place regarding my workout volume and diet and have
been able to hit the spot where I am dropping weight, but still packing on quite a bit of muscle.
Thoughts?
If anyone cares:
Total T:1215
Free T:302
E : 88 (no sides and dick works a little too good)
