here is what i think you should do..
stop the deca, continue running test e for 4 weeks

start the HCG at 1000iu EOD (after you stop the deca) until your balls look normal or bigger, then back the dose down to 500iu E3D or so.

when you have your last shot of test e, stop the hcg about 8 days later. start an aggressive pct (like something below) around 12-14 days after the last shot of test e

week 1-6 nolva 40/20/20/20/20/20mg ED
week 1-6 torem/(clomid) 60mg ED (50mg ED)
week 1-4 aromasin 20mg ED

or even longer.. someone else can chirp in on this, but i think this would be something that would work well
