by far the most helpful *for me* was https://www.amazon.com/Pituitary-Tumors-Comprehensive-Interdisciplinary-Approach/dp/0128199490/ref=sr_1_11?crid=1GFUFH7DKAU90&keywords=pituitary&qid=1640815602&s=books&sprefix=pituitary%2Cstripbooks%2C65&sr=1-11 it's a great complete overview of everything pituitary and offers many citations that allow you to dive into a deep rabbit hole, granted if you have an adrenal tumor it's not as helpful but it does have interesting section on Cushing's, and post-operative care that might be applicable. Let me know more, dm me if you feel more comfortable and I'd be happy to do some research with you
I have absolutely gotten them on my fupa from this. They are dark and purple. My sister in law swears by this stuff to get rid of stretchmarks, she used it through her pregnancy. I have some, but haven't used it enough to say one way or another.
Did they not give you one of these? Those are generally standard that they give you with the big container for All The Pee. If they didn't, try seeing if you have maybe a Quest Diagnostics nearby or call the doctor who ordered the test and request one. As a person in the same boat it's pretty much impossible to do the collection without one of the commode collectors. You can get the one on amazon but and lab worth their salt should just be good to give you one for free.
If THAT'S out of the question, i recommend using a measuring cup, like a glass one. 2 cup capacity MINIMUM. like a pyrex one? Sterilize before use and....well.....pop a squat when it's time to go. Really not ideal but better than straight into the Pee Jug.
Good luck, I hope any of this helps!
