Hello. I've tried different types of anabolic steroids. I started with just testosterone at 600mg but didn't feel any effects. Then I added dbol. I haven't used any AI. Despite taking 600mg of test and 50mg of dbol, I haven't experienced any estrogenic side effects. I haven't seen any results or felt any different. I also haven't experienced any side effects. I've tried about five different brands of test and dbol. What do you think could be the issue?
