Aside from coming off completely and waiting for them to get back to their initial size (which might never happen depending on how long you've been on gear), other than HCG not much you can do while you're on, whatever your dose TRT or more...
Ballz are over rated bro. I transition for blasts then cruise on trt. They come back slightly...but when I blast again and the right always shrinks more than the left. Comes with the territory. I would also agree with nabz you only really notice with hcg on trt, and I get the same nut pain.
I know this feeling as I've been on TRT for a little while now, you get use to it, but I do sometimes think about how I miss the size of my old balls, lol. I'm not even on hcg either, just straight test.
You guys are hilarious op try this link there's a clomid thearpy that bigA suggest maybe it will help i tried something similar when I first started but after a while I said fuck it my wife don't care and I can hardley notice if there smaller or not. http://www.professionalmuscle.com/forums/showthread.php?t=1158
i used to let this bother me haha.. no biggy man. run some hcg if you want to puff them up. but i thing its risky to chance burning up ledyig cells just to have puffy balls... just worry about it after blast
