Purity and identity, verified by independent laboratories — then put on paper for anyone to read. Here's exactly how every batch earns its place on the shelf.
HPLC separates a sample into its individual components and measures each one, giving a precise purity percentage. It's the industry standard for confirming a compound meets our 99%+ purity bar — and for catching anything that shouldn't be there.
Mass spec confirms identity. By measuring molecular mass, it verifies that the compound in the vial is exactly what the label says — the right molecule at the right weight, not a look-alike.
Testing is performed by independent laboratories, not in-house. We don't grade our own work — the purity and identity data come from outside our walls, so the results are objective.
Every batch's COA is published openly in our library and linked on the product page. You can read the actual data — purity, identity, batch and lot — before you ever place an order.
Every claim on this page is backed by data you can read yourself.
