What counts as a US vendor here

One thing, stated so it can be checked: the vendor publishes a United States postal address on its own site. That is a fact with a source and a date, which is why it is the test.

It is deliberately not a claim about where the peptide was made, where it ships from, or whether the address is an office. Several addresses above are registered-agent or mailbox suites, and two vendors share the same Sheridan, Wyoming building. A published address tells you there is a jurisdiction and an entity to write to. It does not tell you there is a warehouse.

12 indexed vendors publish no address we could find. They are absent from this page because their country is unknown, not because they are known to be elsewhere.
