Each certificate covers a single lot. The three figures above are the ones worth comparing across lots — the certificate itself carries the rest, including the methods each result was produced by. The lot number printed on your vial matches the one on its certificate; scan the QR code on the carton to go straight to it, or verify the code on the certificate directly with the laboratory.
Our testing partners
We don't run these labs and we don't get to negotiate the number. Samples go out, results come back, and what comes back is what gets published.
What makes a certificate worth reading
Nobody with a stake wrote it
None of the labs we work with have an interest in GLP3, and none of them sells what we sell. That separation is the entire reason a certificate carries weight — a number from a lab with something to gain is a marketing claim on a laboratory's letterhead.
One number is never the whole picture
Purity tells you how much of the sample is one compound, not which compound, and nothing about what came with it. So every report pairs the HPLC figure with mass-spec identity and an endotoxin result. One number alone can be true and still mislead.
You can check it without us
Every lot's certificate is tied to the lot number printed on the vial, and each laboratory keeps its own public record of what it issued. Scan the QR code on the carton, or look the lot up at the lab directly. You should never have to take our word for any of these numbers.
