No, it doesn't. You'll be VERY hard-pressed to find one of them locally anyway. And it likely isn't required. Most are happy to accept pure informed consent. Others, a general "evaluation" will suffice, rather than 'proper' therapy. And it's more a legal formality than anything else (if a "group practice", they don't want any liability should, for any reason, one 'regret' transition later... it happens). It's basically just to ensure there's no actual "mental health" problem influencing your desire to transition. Perfectly reasonable 'condition'.
'Best', is entirely subjective. For affordability? That's virtually always going to be IM (original/oldest patents). For results? That's really indeterminate (and regardless of how it gets there, as long as it's there, it will be used and you will see results). However, IM is as close as you can get to how it otherwise happens for 'cismales'... so... there's that (and you can forget about it for 1-2 weeks, which is real nice IMO).
Injections aren't so bad at all if someone else is administering them (especially if sticking glutes IME). I don't like sticking myself any either, but I will when I have to. And it sucks, feels a bit chit, but you gotta do what you gotta do. I just clear my mind (music really helps), bite my tongue and sink it. You can't think about it or you'll sit there for hours procrastinating lol. Ah right, 23-25G are ideal needle gauges for IM (don't let them try and give you any of that 21g+ much too thick for quads).
Personally, I wouldn't be happy with pellets, patches or gels (and THEE more expensive options). Was recommended I try switching to gel because the IM is affecting my hemoglobin a bit (54% at highest. 60% is the danger zone), but elected instead to donate blood every 3 months (perhaps more frequently if required). Don't want to deal with the other administration methods (and really couldn't afford them anyway... I mean, gel is practically $300/mo!).
Oh, but, ask about SubQ administration. It's better, in so far as you can use a really small, short needle and there's also then no muscle scarring, no risk of hitting nerves/veins etc. It's just, apparently, a pain to find a doc/endo that's informed enough of it to monitor that properly. Otherwise that's what I'd be doing.
