Yes, I believe most people buy directly from somewhat shady Chinese factories. I tried contacting a few and they all refuse to meet or send samples from within China, so I assume what they're doing is illegal in China. In the US, it's legal to sell them as a "research chemical" but the FDA is cracking down on companies that are clearly engaging in b2c.

There's this company that offers free testing: https://finnrick.com/

Another popular testing company is https://janoshik.com

Some other useful resources: https://graymarket.substack.com/ and https://glp1forum.com/

There are a few subreddits as well.

FWIW, I never ended up buying any myself.

Right, but I don't know the people at those companies. I have local chemists that I trust. I'm just lamenting the fact that developing that kind of trust network everywhere, so everybody can be similarly sure of what they're putting in their body, is likely to run afoul of local laws.

FWIW, finnrick's claim to fame is being free. Someone is paying for it. They have also failed blind tests in the past, Janoshik (IIRC) never has. There are several US-based labs but none of them have the same reputation as Janoshik.
