    Weird IGF-1 results

    I just had some labs done and one thing I find kind of odd. When I am on .5mg of genotropin my levels are around 196 so doc will raise my dose to .6mg and it will shoot up to 336. Seems kind of odd the drastic level changes. Doc is thinking it may be due to no longer having infection in my body...

    What can cause testosterone to crash suddenly??

    My testosterone without reason suddenly took a huge dive downwards. Without a change in amount taken or any change in protycol such as type of med or injection site. It went from 600 down to 237 suddenly.

    T3 question

    Do I have adrenal insufficiency?

    Thursday I am getting an ACTH stim test. Right now I replace growth hormone, thyroid, and testosterone. Might as well add cortisol and aldosterone right? I hate my pituitary gland.
