I am not resident of the USA, but here in Australia there are a few GP's who specialise in GID care, I am under care of one of those.
Surety firstly and then Blood tests are necessary for your own well being, there should be some questioning on your general well being as is... e.g. are you healthy, any blood-clotting, history of... in you and your family line, blood tests are needed day one, then probably a month or so after, three months then as your GP will want/agree with you... well that's how it works with me, only thing is can't prescribe or implant pellets or allow self injected hormones, pills only!
But as I say that's my GP in Australia...
For me; Endo in a few months for me, then get shot of the oral stuff...
