It's a shame that this person was in such a difficult situation, but, barring some extraordinarily rare reaction, a few months would not cause long term problems. The full impact takes several years, by 3-6 months the very first changes are only starting to become visible and many of them are things like changes to skin quality and fat distribution which revert after cessation.
It's still possibly a failure that your acquaintance got on HRT or Lupron in the first place. Given that long term follow ups show, consistently, that less than 2% of trans youth "desist" and are happy with their treatments, the reasonable solution to that failure would be to require some sort of evaluation by a therapist who has been trained to spot when someone has gender dysphoria and belongs to that 98% of happy transitioners versus someone from the 2% group that will desist because their issues came from somewhere else.
Instead of that sort of reasonable response, we see calls for outright bans on all treatment with many also calling for banning treatment for adults and a reversion to conversion therapy as the only "treatment" - it's not a treatment because it doesn't work and just hurts people.
The reason for this, is that the vast majority of people who suddenly have such strong opinions on trans health care are not actually concerned about people's health. They've just found a way to make their prejudices against transgender people sound like reasonable concerns.
And "someone who did this under duress regretted it hence no one should do this" isn't a sound argument.

because it's more socially acceptable to discuss these issues than it was 50 years ago...
it is also undoubtedly true that it is more rewarding on a political level to not have any doubt on these issues than it was just 10 years ago.
Entire careers have been built on it. On both sides.
But, incredibly enough, the ones on the "precaution" approach are on the far right side.
If we saw the same increase in cases of kids having mental health issues, which is also more socially acceptable to talk about than 50 years ago, we would be worried sick, we would ask why it happened and what caused it, not simply treat the symptoms and call it a definitve solution.
studies would also show that their life is better than when they were not treated, but is relying on anti depressants really a good life?
is asking the question proof that the person asking hates (or is phobic of), for some reason, people with mental health issues?
I cannot imagine a greater horror then having gender dysphoria, knowing exactly what is wrong, and still being forced to go through the wrong puberty (which does inflict irreparable harm, for us) because some "concerned" parents want decades of medical history on blockers before they deign to allow you to receive medical care. I wonder how that medical history is supposed to be built if no one is allowed to take blockers?
I'm not even going to engage with your bad faith argument that trans kids are only in the last 2-3 years.
I'm not under any illusion a person with your opinions could ever be swayed, but hopefully other reasonable people will see this comment and not fall victim to your scare tactics.
