I doubt its from hcg, ur using like 1000ui/weekly (or ur just hyper responder) btw its worse using eod than 2x week, because e2 peak is 24hrs from your pin..
Under normal circumstances, roughly 20% of TST aromatization occurs in the testes. If men start taking AAS, which are suppressive and reduce the production of endogenous TST in the testes, aromatization in the testes will decline. Adding HCG to the cycle will in turn return it to its original level, which should not exceed 20% at normal HCG doses of 250 to 500 iu every 3 to 4 days. In other words, at normal doses of HCG, you don't have to worry about too much increased aromatization activity and therefore high E2 levels.
