Batch COA
For every lot of a stocked peptide the batch COA reports HPLC purity, MS identity, endotoxin and fill. Here are previews of every batch COA and test report we show, what each result means, how to match a COA to your vials and how to ask for it before you order.
Batch COA
Every lot of a stocked peptide has its own certificate of analysis. Ask for the COA of the batch you are quoted before you order — the batch number on that COA is the batch we ship.
On every batch COA
Lot number
The COA names the lot, so it matches the vials you receive.
Agreed in writing
Any other test is agreed in the quotation before the order.
Report previews
Each picture is the first page at low resolution, with numbers, dates and signatures covered, so the small print cannot be read. The full, clear copy comes from sales — ask for it by product and strength.

Match the lot
Ask for the COA of the batch you are quoted. The batch number on that COA is the batch we ship.
HPLC purity
Compare the result with the purity specification on the product page; the specification is the minimum.
MS identity
Compare the mass with the molecular weight on the product page and the form it refers to — free peptide, salt or copper complex.
Endotoxin and fill
Endotoxin is reported with its unit; fill is the amount per vial, to compare with the strength you ordered.
Step by step, with an example: how to read a peptide vial COA. Masses and CAS numbers that differ between listings: why they differ.
Quality guarantee
Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.
How the refund worksHPLC purity, MS identity, endotoxin and fill, on the COA of every lot of a stocked peptide. The COA carries the lot number, so you can match it to the vials you receive.
Yes. Ask for the COA of the batch you are quoted; the batch number on that COA is the batch we ship.
Yes: HPLC purity and MS identity reports from a third-party analytical laboratory in Tianjin, China, on Acetyl Octapeptide-3 (10 mg), KPV (10 mg), Retatrutide (50 mg) and 5-Amino-1MQ (5 mg), and reports that customers commissioned from an independent laboratory on KPV (10 mg) and Retatrutide (20 mg, 60 mg). Low-resolution previews of the first page are on our Batch COA page and the product pages; the complete report is available from sales.
Because listings describe different forms: a free peptide or a salt (acetate, TFA), a copper complex or its free peptide, one peptide or a two-peptide material — and some registries keep older numbers. Each product page says which form its values refer to; the COA of the lot is the reference.
As stated on each product page: refrigerated and protected from light for most peptides, and the conditions given on their pages for the solutions. The COA of the lot gives its storage conditions.
