At the age of 43 in 2003, I underwent a craniotomy to remove a pituitary cyst. During that surgey I lost pituitary function and became Adrennal insufficeint as well as steroid insufficient. I immediately began taking supplemental steroids and hormone replacement meds. After a few years I was still not feeling myself. My physical drive was sluggish. I had difficulty exercising for very long and as a result was losing my physical stamina and strength, both which are incerdibly important to prevent osteoperosis as well as to maintain long term emotional and physical health. My doctor mentioned that some replacing the normal testosterone level at my age my help. It really has made a huge difference for me and I have since been able to consistantly lift weights and do cardio workouts. This treatment is controlled and very effective. Please continue to provide this medication to prevent further health issues both physically,, mentally and emotionally. Thank you!
