I'm not an expert at all, but I can tell you that just for low T my doctor was injecting me with 160mg a week and giving me 1000mg HCG + 1.5mg Arimidex. I went to a more "performance" based doctor, and he upped it to 300mg a week of Test C. The second doctor kept the HCG the same but doubled the Arimidex. Most guys I talk to that I know are on gear don't do less than 400mg of Test a week. If I were you I'd watch Seth Feroce's "Drugs, Steroids, and Life" series, he goes in depth on what he does or has done (part 4 specifically).
