Kiwee: I had severe adrenal fatigue years ago but no longer suffer from it. You need to run ASAP and buy a book by Dr. James Wilson called Adrenal Fatigue. This book contains everything you need to know to fix your adrenals. It is without question the best book written on the subject. Hydrocortisone injections are not the right answer and if you go to a doc that thinks thats the right answer then go get another opinion because once you go down that road theres no turning back. Cortisone injections are only if you have Addisons disease. The HGH will help but you need to make sure you take the right supplements and adrenal glandulars etc first (read the book). HGH will further make you tired by increasing the demand for thyroid hormones so if your already feeling severe fatigue the HGH will more than likely increase the fatigue.
