Do you need to cycle thymosin alpha 1?
Studies in people do not establish an on and off schedule for thymosin alpha 1. It is approved as Zadaxin in more than 30 countries, mostly for hepatitis and as an add-on to help the immune system. That label sets a fixed course of treatment, not an open-ended cycle the user picks. On and off schedules for research vials are unverified. This site does not invent a schedule.
