Nominal sizes describe the product label; measured results are listed in each batch report. Published reports do not confirm the batch allocated to a future order.

Product & documentation questions

How do I read the size and pack quantity?

The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.

How do I find the matching COA?

Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.

Does a purity result mean every test passed?

No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.

Research Information
