how old are you? whats your past cycle history? is it test only? no nandrolone, trenbolone, or any other compound? is your test from a reliable source? if the test is real, theres no way possible that ur ED is from ur natural test being low. at 500mg a week, your levels should be like triple what they are naturally. hgh will do absolutely nothing for ED. have your had any kind of medical conditions in ther past? when this happened on mdrol, did u just wait it out?
