Hello all Getbiggers! I usually blast 750 mg/week test E or C and cruise on 140-150 mg/week. The point is that this cruise dose gives me free testosterone in the range of 3500-4000, while the norm is 300-900. I usually get tested 2 months after going on a cruise so that the testosterone has time to drop. Does anyone know why this happens? I've never heard anything like that from anyone. Even my powerlifting friends don't know. When I am on 750 mg/week the result is off the laboratory scale. I will add that I do not need to take ai at all because my estrogen is normal on every dose of testosterone.
