I have not, but all of my care is free through the VA.
My only question is how they plan to monitor your hormone levels?
HRT should involve a lab test to check your baseline levels and determine how much of an increase is needed, whether T-blockers are required now or can wait, etc. After starting HRT, they should do follow-up labs at 30-90 days, then can extend those to 6 months to a year.
Monitoring is crucial to ensure health and safety. I would definitely ask about that. You might be able to do out-of-pocket lab tests, then send them the results. That way, they can make appropriate adjustments. If they are willing to prescribe without lab tests, run away. That is a good sign of a scam.
Don't play games with your health. You only have it for a short while.
