I could be wrong about this but from everything I've read concerning HCG there is a significant danger, as Vette stated, with desensitzation of the Leydig cells when using high doses of HCG for a prolonged period. Also high doses of HCG have been found to raise estrogen levels a bit more than Test levels. The fact that you were using Test for such a long period without the use of a product like HCG to keep your testicles working suggests to me that there is probably a limit to what it can be expected to do for you now.

There is a product that I've recently discovered and will be talking to the folks at the clinic I am involved with called HMG (Human Menopausal Gonadtropin). It affects FSH while HCG primarily affects LH. From what I've read there are definite benefits to running the two of them together in order to get the testes working. But again having gone so long without doing anything to keep your testes functional in the first place I'm not knowledgable enough to say it will be the answer to your problems.

Do a little bit of research on it and then see if your doctor is aware of it.
