it's a damning indictment of the medical system that the sole and only only medical professional I've spoken to who knew more than me about my care was an endocrinologist at the fucking mayo clinic. you don't get to talk to me like that, pharmacy tech.
my answer to your opinion is "and yet I've done it in real life, largely because of people like you", but let's take it from the top:
are you allowed to interpret that date or do you just know that you can't use it after that date or you get in big trouble? if you have some kind of argument here, I'm open to hear it, until then my rebuttal is "doesn't work like you think it does"
what contaminant, exactly, do you think is going to colonize a hermetically-sealed vial of oil and preservatives? oil famously does not rot, it goes rancid from oxidation. it's literally a vial of preservative with hormones and preservatives dissolved into it, the only contact with the outside world is a needle that was in sterile packaging eight seconds prior. it's really obvious you didn't think this through.
this one is kind of funny to me, it's very "I can feel my reach exceeding my grasp, shit, throw everything at the wall until something sticks". so what? let's say you lose half of it, congrats, it only lasts one year. next time you're at work, look up what a vial of estradiol valerate costs without insurance. you're asking people to pay that every month, how much more is that than six or eight bucks? order of magnitude, right? right.
do you typically recommend people use separate draw and inject needles with a luer lock/slip syringe, both of which are somewhere in the neighborhood of 18-23g? well stop it, you're making people risk coring their vial for no reason. I used a 29g fixed-needle insulin syringe, it worked just fine. "but what about needle dulling" would you like to see microscope pictures I've taken in the course of arguing against the advice that people in your position commonly give to people like me? why, exactly, does it work for diabetics and not us?
please understand that you have chosen to volunteer yourself as representative of a medical system that fails us in elaborate ways. consider that you are wildly overconfident, that you're ignoring the fact that we are within your expertise but outside of your experience. there is a world where you go, "oh shit, there's stuff I don't know" instead of casually dismissing the many thousands of trans people who've done what you think is impossible.
I would like to be able to tell people, "ask your pharmacist" without having to list the half dozen bullshit cargo-cult ideas they might get told and why they're wrong. I would love it if you learned from this exchange.
honestly though? I kinda figure you'll get mad at me, double down, and try to reinforce your status as an authority figure without really feeling obligated to engage with anything I'm saying. that's how this usually goes, you see.
after all, you didn't ask any questions before trying to prove me wrong, did you?
