“I want to start with 500IUs per week, i keep reading that this should be enough or is it not ?”
Right, anything from 250IU twice a week to 300IU three times a week has been used with success. If it is me, I’m doing 250 three times a week or 350 twice. You can use testicular size as a guide, if they are not atrophying, you’re good.
“this was not sensitive test tho, here where I live there is no lab that would test for sensitive, all of them just do the main ‘‘female’’ one.”
No big deal. Rarely is the difference between the two clinically significant. As always, go with how you are feeling regarding E2 management. Below is a link to a thread which shows examples of both tests run concurrently. Check E2, monitor it, and if you are not sure if any symptoms you may have are due to E2, check your blood and see if it has changed from baseline.
Good luck.
