Let me know how the auto-injector goes, my experience with the oil is that because it’s so thick and going through such small needles, it injects slowly and requires more force on the plunger than typical injections, so I would imagine an auto-injector would be tricky to get to work. (I once had a pharmacist go on a full-blown rant about how my endocrinologist must not know anything because the oil could not possibly go through the needles he ordered, which of course was false, it just takes patience.)
I will say, you do get used to pushing the needle in and there are lots of coping mechanisms, so don’t despair if the auto-injection doesn’t work out.
Ah, I think they just don’t want people who are anti-trans posting here - I think allies are fine. If you do have questions about trans folks that you feel wouldn’t be welcome here, you’re always free to DM me and I can try to help answer them.
