HCG can directly increase testicular estrogen. The testes produce around 10-15% of a males estrogen (healthy). HCG can directly stimulate this and an AI will not help. Tamoxifen will help block this testicular estrogen.
The other pathway is HCG increasing endogenous testosterone by stimulating the leydig cells. It doesnt matter if your also using androgens, it will still increase endo. T. The increase in testosterone will then cause an increase in estrogen via aromotasation. Which an AI will help.
HCG will also increase progesterone via degradation of testosterone.
I always think an AI should be used at a low dose, unless your using HRT doses. Elevated estorgen can cause a host of problems, as can reduced estrogen (CNS function, labido, testosterone synthesis, GH and IGF production, bone density etc...) so keep it in NORMAL ranges.
