WTF is any of this, is there some ELI5/OOTL explanation?

I work in big tech and have never heard anyone talk about "peptides". Is this a startup scene thing or just an SF thing? (I live in New York)

all of my coworkers are pretty normal, sure there are the stereotypical fitness types that are marathon training, cycling, or have a climbing gym membership but no one is talking about buying weird Chinese drugs

Wegovy/Ozempic (semaglutide), Zepbound/Monjourno (trizepitide), etc are the GPL-1 drugs sold today for diabetes and weight loss. Technically they are peptides. So if people you know have "finally" lost a lot of weight, they are likely on peptides.

Peptide manufacture is not as difficult as other drugs because they are injected.

Because the brand names cost a lot, and their manufacture is not too difficult, obviously lots of people got in on the action. Compounding pharmacies, gray market providers, and lots of cheap chinese copies. For one month cost of the name brand you could get many years worth of chinese copies. That is a pretty good hook.

Now that you are injecting one chinese peptide, and it works amazingly well, it is pretty common to check out some of the others. And it is hard to avoid since by the time you find the gray market / chinese suppliers, it is only one of the things they sell.

I'm in western Ohio and had heard about the peptide fervor on podcasts but never IRL. Today, at my daughter's soccer game, I overheard a long conversation between two guys in their mid-40s comparing their peptide regimens (along with just discussing their fitness activities).

I'd never actually heard anybody talk about it before. At first it was the generic CrossFit talk I'm used to hearing, then to diet and recovery / injury stuff, but then it too the peptide turn. It sounded like both of them are injecting themselves from stuff they're buying on the Internet. They both talked about it like it was just the most natural thing.

Derek Lowe had a good blog post about it, mostly about the problems: https://www.science.org/content/blog-post/ah-peptides-where-...

This recent NYer article is a pretty good overview, written by a practicing physician:

I work in big tech and several of my older colleagues are ALL IN on peptides. Fountain of youth stuff.

Frankly as I am aging myself and noticing a lot of changes to recovery time and overall physically feeling good, I can totally understand getting on testosterone, for example, but random peptides that show up in white bags from random Chinese labs? no.

this was formely the fanbase of the dark enlightenment movement. an avantgarde techno-capitalist alt-right underground culture. Musk, Thiel, a16z, Altman, Srinivasan, many in the Trump administration (including Vance) have acknowledged their involvement with it. the ideological underpinnings are mainly given by two philosophers/bloggers: nick land and curits yarvin. the rest of the people at those parties are like a fanbase to this movement, but it includes podcasters, influencers etc. mostly edgy upper middle-class american kids. the characterization is pretty accurate and nothing new.

https://www.newyorker.com/culture/the-lede/silicon-valleys-f... (recent profile on land. only skimmed it)

but apparently after the catastrophic failure of the MAGA movement they're shifting gears:

> A year ago, when I last wrote about the Bay, I was surprised and dismayed to find that edgy right wing black pilled nonsense was considered ‘cool’. ...... Sometime in the last 6 months, everyone collectively decided that being super right wing is actually really cringe. ...... But regardless of the reason, everyone agreed: “wow, it’s kinda really embarrassing that we spent so much of last year partying with real life eugenicists.”

Edit: New York had pretty much the same thing, called the Dimes Square movement. it was linked to the controversial remilia/milady NFT collection
