First, your body will adjust over time as long as your HPTA is not shot. You should see a real TRT doc to get this straightened out sooner. Otherwise you need to wait it out and hope your testicles will regain adequate ability to produce testosterone.
There are PCT protocols for those that want to come off for good or extended periods. These involve the drugs heavyhitter mentioned.
6000 IU/week is super high - I was shut down pretty hard and felt my balls aching very shortly after injecting 500 IU intramuscularly.
After aching a few days they eventually stabilized and I now take minimal amounts as a maintenance dose.
I would drop the dose down and if you don't feel anything happen in another ~3 weeks or so, I would be skeptical of the particular product you're using or look for something other than HCG to solve your problem.
6000iu of HCG a week is way too much. HCG is to help preserve your testes and increase your pregnenolone levels which will give you mood support. what you are doing did not work.
at the very least get estradiol blood lab work and post it along with the ranges here. friend, you need serious anti-aromatase help and i'm asking you to post labs here for benefit of you and others. seriously consider also getting lab work for testosterone, free testosterone, hematocrit, cbc, psa and a digital rectal examination (DRE)
