I'm willing to bet that, for some, to get your T levels high enough with just
HCG would require quite a bit of it which would then elevate your E too high. That could cause the disparity between T and
HCG therapies. I'm also guessing that since HCG raises other levels that it may raise one of them too high which could cause negatives as well.
As for restarting the HPTA.....I just can't see how this would be possible. HCG basically mimics LH right? So it is suppressing LH production. SO, when you come off of HCG the pituitary won't be producing any. How's this restarting? Although I did just think of one reason. Could it be possible that the gland is overstressed and overworked? Then, by allowing it to shut down production for a while you are giving it a rest. Then, when you come off HCG it's "ready" to go back to work? A theory at least.
