Wow, a warm hello back at you. The standard line for DIY hormones is don't, but since you are going to regardless, start very slowly and get some baseline blood work done first. No point in cooking your liver eh? Are you planning on getting started with counseling? A good gender specialist helped me figure out a lot of what was going on, and has been an invaluable ally as I have grown and learned about honesty and authenticity.
All that said, welcome and I look forward to hearing your story my amazingly decisive friend. I cannot imagine moving that quickly, it took me decades of angst and dithering to come out full time. If I had your courage I might have saved myself an awful lot of heartache, I truly wish you joy.
Fair winds and calm seas,
Julie
