My brother is much younger than myself, and he has an autoimmune disease that I will not go into on here. Let's just say it kills a lot of people his age (he was in the early 40's when it was diagnosed). To make this story to the point of the headline, his docs scripted Test Cyp for him to help out about 5 years ago and they even encouraged to let it get him up between 1150- 1200 level, which he did for over 4 years. Due to the autoimmune disorder his baseline reading was 140 or terrible total test levels.
After a little over 4 years his triglyceride levels and other cardio risk factors were starting to rise, so he decided to go off the Test Cyp for a long time. He has been off the injectable Test for about 9 months now. His blood test showed his Total test levels to be still slightly above 700. Amusing as he did not use a pharm HCG. Yet many of his other health factors have improved, and he does take some natural supps that would help keep his test levels in good order. I'm not saying I understand this, but it is interesting.
