Besides what these guys are trying to be helpful with the first and foremost is that most all guys are Primary HypoGonadal, the problem is the testes. So, there's little reason to think that stimulating the testes with HCG mono level doses is going to result in much. It's much more likely in that scenario to get Estrogen production. If you could make your own T you likely wouldn't be in this situation to start with so it's just not logical to try it.
Guys that are secondary could have a reasonable response.
