The limits behind those lines

The table above says what the document shows. These are the limits behind it: the specification a batch is measured against before it is allowed to be sold, with the certificate stating the limit and the batch’s own result side by side. The 168 lines on the price list are governed by 5 lists, printed in full below, as they stand on .

The list most lines are released against 161 lines

161 lines of the 168, 75 compounds, carry these lines on every certificate. A batch that fails any one of them is quarantined and does not ship.

Questions about certificates

Are your certificates of analysis public?

Yes. We publish independent third-party certificates for every batch we ship, 60 of them live on this page right now, each released at 98 to 100 percent purity by RP-HPLC. Any batch can also be looked up here by its number with no account and no sign-in, and every certificate carries a QR code that verifies it with the laboratory directly. The reports cover identity and purity along with the other release tests on the specification.

What is on a Peptides Wholesale certificate of analysis?

The batch number as it is printed on the vial label, the product and its presentation, the date of manufacture, the date of analysis and the retest date, then one row per release line: the method, the limit and the result the batch gave. The lists above are the whole of it; nothing is left off a certificate that is on the specification.

Where do I find the batch number?

On the vial label and on the carton, and on the packing list against every line of the order. Any of the three is the same number. Enter it in the box above and the record comes back with no account and no sign-in.

Does every box come with its certificate?

Yes. The certificate for the batch travels with the shipment or follows on request, and the number on it is the number on the vial. A box whose batch has no certificate on file does not leave.

What if my own laboratory reads something different?

Send the desk the batch number and the result. Retained samples of every batch are held for twelve months from its last dispatch, so the same material can be pulled and run against the same specification rather than argued about.

How long is a certificate good for?

Until the retest date printed on it, which is set from the date of manufacture and the shelf life on the list above. Stock is picked oldest in date first, so the batch that reaches you is the one nearest its retest date and never past it.

Batch numbers are built from the year and month of manufacture, the product code and the batch sequence, so the number identifies the line and the month without a lookup. How a batch is released.
