The sources behind the catalog
Every compound is sourced from independent vendors, and they differ in what they offer. The badges — batch-matched COAs, a warehouse in your region, traceable batch numbers, outside lab testing, a published COA library, reported fill volume, endotoxin and heavy-metal results — appear only on the cards of vendors that actually offer them, so read the card, not this list, for what a given vendor provides.
A COA covers the lot it names and nothing else. We publish lab results pass or fail, but not every lot is tested, and there is no guarantee your order ships from a tested lot. The COA library shows exactly which lots we publish results for.
And here's how each one actually performs. Speed and reliability come from orders we placed and parcels carriers scanned — how fast they dispatch, how often a parcel lands inside the window they advertise, and how many of their buyers come back. Every scorecard says where each figure came from, including the results a vendor reported itself. Compare puts every source side by side on the same measurements; switch to Cards to read one vendor at a time.

Speed and reliability figures are measured from every order we've shipped. Vendor tests are results the vendor ran and reported to us, not certificates in our COA library. A dash means we don't hold enough yet to publish that figure — not that the vendor scored zero.
