Caffeine is an insecticide.
This approach demands complete ignorance of how chemistry works. That's not how you should evaluate a drug. This is how Facebook moms evaluate drugs.
Things like capsaicin, piperine, caffeine, penicillin and many more are all derived from defense mechanisms in various species - and a few of those mechanisms target mammals specifically. Which doesn't actually obligate them to be harmful to you in any way.
We have more than enough Facebook moms on Facebook. We don't need any of that anywhere that matters.

And the gila monsters have their own circulating serum levels of exenedin-4. It's produced in their salivary glands - it's a component in their venom, yes, but they also ingest it themselves, particularly when eating.
But these are fundamentally analogs to our own hormones that have been tweaked to increase desirable properties. It's not like we isolated some random compound that our body has never had to deal with before. (Not that I think that that would necessarily be an indicator we shouldn't use it, either. I don't see why any of this is a strong argument to you, even if your understanding was correct.)
Humans did not evolve for an environment where food is overly abundant and physical activity is optional. For almost the entire evolutionary history of humans, this just wasn't the case. But it is what humans are having to deal with today.
Now, take a look at the "metabolic syndrome" and its prevalence. Clearly, there's a lot of room for improvement.
By all accounts, this generation of GLP-1 agonists has found a meaningful way to improve on that baseline. The benefits are broad and the side effects are manageable. This isn't "surprising" as much as it is "long overdue".
1. We have to trust the data of for-profit pharmaceutical companies and their trials. They are incentivized to produce optimistic results.
2. It's relatively new (insofar that a lot of people are taking it). Opiates were touted in a similar way until the other shoe dropped. There exists an undefined line in time where I would feel more comfortable.
3. It is/was made of a poison from an animal.
4. The extreme benefits are overwhelmingly in obese candidates. Keto is the same way; I tried it and it was not for me because I am not obese.
I'm actually open to any sort of evidence that will change my mind. No name calling please.
