I really dislike that most stories try to taint it in the "diet trend", "TikTok challenge" light, obesity is a serious illness which is extremely unhealthy and leads to many many preventable deaths, this drug is a miracle.
And yeah, there shortages, but then the drug stores shall give out this drug to those who need it the most, and not who pays the most. It's not like the US healthcare system is fair anyways. And also the suppliers can ramp up production (as they are already doing).
Friendly reminder: The STEP 5 trial of semaglutide showed that even in long-term usage a sort of "cutoff" BMI is reached, so even skinny/normal bodied people who take semaglutide don't drop to an anorexic level BMI, but stay above the 18.5 line (after which you are considered underweight) [1].
