alt Hacker NewsThe Atlantic did a write-up in December [0] about retatrutide availability and they named at least one well known vendor (who also sells tirzepatide, semaglutide, and all the other usual peptides). Not the cheapest vendor, but well known, does the batch lyophilization in the US, still takes credit cards, and gets pretty solid group test participation due to their popularity. And if you know how their pre-sales work, the price premium isn't too terrible, worth it for the test participation IMO.
If you want to know who else to avoid, join the Discord the vendor links to from their web page and ask around in the general discussion topics, people will share.
> does the batch lyophilization in the U
Nexaph does not lyophilize in the US despite Cain's claims - if you're buying from Nexaph, do so because they're popular and well tested by 3rd parties, but not off of anything they're saying about themselves. Hell, just go to the About page and you can find an artifact from back when Cain was lying about Nexaph being a chinese pharma company that had mRNA vaccine production experience.
That's also why the "presale" periods are cheaper - just letting them know how many vials to put in an order for.
