No Bass it won't. Your Pituitary is shut down that's why your numbers are almost non-existent. What HCG does is replace the LH that's not being produced anymore so your body can function correctly.
And yes, all men on TRT who are shut down are in the same boat. Without HCG during TRT it's almost impossible to restart again...although in some cases it can be done but it's rare. On HCG during TRT re-starting has a much better chance.
