Every batch we hold carries a unique reference, and that reference is printed on the vial you receive and recorded against your order. It is a small detail that does a lot of work.
The reference is what ties a physical vial back to a specific batch. When a batch arrives it is checked against independent third-party analysis before it is released for sale, and it is held against its reference the whole time it is in storage. So the code on your vial is not decorative — it is the thread that connects what you received to the batch it came from.
That traceability matters if you ever need to ask a question about an order. Because the reference is recorded against your purchase, we can look up exactly which batch shipped to you rather than guessing.
We do not publish unverifiable purity figures, and a batch reference is not a claim about performance. It is simply a record — an honest, checkable link between the vial in your hand and its batch.
