Your ... friend ... might want to reconsider. I have knowledge of ... a friend ... who took masteron, but was underwhelmed by the prosexual effects. Apparently it depressed estrogen too far, causing my ... friend ... to actually have a lower libido. Test would seem to be best here, when dosed at 600 mg/w or higher (Bhasin had a study that showed prosexual effects only at that dose, nothing lower).
