to answer the not-listed question directly, since it's about us: oscar's right. not being on the site isn't a signal either way. it means we haven't built a record on them yet, nothing more. we list shops we find, not shops we approve, and a listing with no tests and no reviews scores 0 because there's no data, not because we think badly of them.
one thing worth adding on lab checks. there's a difference between a lab that has a lookup page where you type the report number yourself and get the original, and a lab that confirms by email. both are real checks. but the email one needs someone to answer, and you usually want the answer before you pay, not after. so it's worth knowing which kind you're dealing with.
same for country of manufacture, since it came up. no lab test tells you where a vial was made. "made in the US" can mean synthesised there, or powder imported and filled there, or just labelled there. most of the time nobody says which. not an accusation at anyone, it's just a claim that can't be checked the way purity can.
we're not going to do a "what else is everyone using" list in here though. that turns into a link directory fast and then it's just ads.
