If you are taking perscription medication perscribed to you from a doctor, clear anything and everything with him/her before taking something.
Check out Retain 2, by Anabolic Xtreme (direct cortisol control), or (often used in PCT for cortisol restriction).
Then there's an additional product that others will probably also chime in about - Reset A.D., by Palo Alto Labs. Designed to treat Adrenal Fatigue by helping the recooperation process.
Again though, check with your doctor. No a clue what your medication does precisely, and adverse reactions between drugs can set you back even further.
