Fix the test and thyroid first, and make sure you're getting adequate caloric intake to cover daily needs and plenty of protein. Then give it 3 months and recheck the GH/IGF-I axis as well as cortisol. Cut back on the coffee.
You're trying to fix the low thyroid and test with EPH and caffeine. Just like fixing diabetes with prozac.
The problem appears pretty clear cut, how progesterone cream is going to help is unclear to me. You should ask the doc how progesterone cream is going to fix the low thyroid, test and DHEA levels.
For a doc to help, they have to understand the problem.
