are you taking anti-e or any AI??? you are nearly taking 750 mg. of test E per week, might be the excess of strogens... may be your test is fake....But after 4 weeks, you should have your sex drive up, it actually only takes within a week to "feel" the any kind of test, what it takes about 4 weeks (depending on the ester) is to have it's anabolic effect... hcg right now wont do anything...
