Because it’s a naturally occurring signaling peptide there already exist people who have too much of it and too little of it due to normal genetic variation.
I think our massive advancement in the computer industry has confused people into thinking other industries which use computers are also advanced, but this is not the case. Pharmacology is an extremely immature field.
Edit: I think the only field more immature than this would be psychology? And I don't think many are silly enough to trust a field who still worships a dude that believed every thought you had was somehow actually about sex, and has made zero advancements beyond borrowing meditation and a few other ideas from other cultures.
I think your mind would break if you tried to learn what goes into modern drug design, like quantum chemistry.
Statistical analysis was basically invented to solve problems in psychology and biology, like measuring intelligence and understanding genetic inheritance.
Pretty much all the advancement in the computer industry is on the hardware side. Software engineering is the most immature field of them all.
edit: I should clarify that I did indeed only mean computer hardware - that shit is incredible, and built by actual engineers. Imagine how incredible software could be if we had real engineers there, too.
Also, there's a distinction you're overlooking. Not trusting big pharma isn't the same thing as not trusting medicine. Big pharma will happily sell us drugs that work - it's the most profitable thing they do. You just can't trust them blindly, which is why regulation is important.
In the case of vaccines, they've proven effective over a very long time and the arguments against them are suspect at best. Questioning a new vaccine is healthy suspicion, questioning vaccines as a class of drugs requires a heavy burden of proof.
But of course, mRNA vaccines were being developed long before COVID, so I assume you raised you concerns at that time, and not in the middle of an emergency when nobody has time to explain to every third dumbass that we're going for the lesser harm here - meaning "not dead right now".
It's a good thing I'm not dictator, 'cause I'd have every news anchor and talking head that spread confusion during that time lined up against the wall and shot.
Anyone who isn't incredibly cautious of drug companies claiming perfectly safe "holy grail" medicines is insane. The number of crimes committed by this industry is hilarious and depressing simultaneously. The lack of moral guidance in this industry is incredible. The incredible greed in this industry is unmatched. I can't think of a more devil-like industry.
If news came out tomorrow that everyone who's taken GLP-1 started bleeding out of every orifice until dead, and that this outcome would've been impossible to miss during trials, I'd STILL be more shocked at the people who didn't see it coming.
