Details printed on the document
What this certificate does and does not say
It describes one lot of material as it was at the date of issue. It is not a statement about any other lot, and it does not say the material is fit for any use in or on a human or an animal. Purity is the proportion of the main peak in an RP-HPLC trace at 214 nm, not a guarantee that the remainder is inert. Storage and handling after the material left the laboratory are outside what any certificate can cover, which the storage guide goes into.
How do you check it yourself?
The lot number printed on your vial must read GHK50-0803. If it does not, this is not the document for your vial and the one that is will be in the library. The code COA7628 can be entered at the laboratory's own verification page, which confirms the document against its record rather than against ours. The guide to reading a certificate explains what each figure means and what a certificate that omits one of them is hiding.
The laboratory's PDF
This is the document the figures above were transcribed from, published exactly as the laboratory issued it, with nothing removed or redrawn.
