Quality

Third-party testing

Lots are tested by an independent analytical laboratory, not in-house. An in-house purity number is a self-assessment; a third-party result is checkable by someone who does not work for us.

Testing laboratory: [[LABORATORY NAME]].

Tested per lot, not per product

A certificate belongs to a lot, not to a product line. When we release a new lot it is tested again, and the certificate published against it is that lot's certificate. We do not carry a previous lot's result forward.

What is tested

[[TEST PANEL — e.g. identity by MS, purity by HPLC, net peptide content, heavy metals, endotoxin, sterility]]

Traceability

Every vial carries a lot number. That lot number is the key to its certificate: you can look it up without contacting us, and the result you find is issued by the laboratory rather than by us.

Handling and dispatch

Material is held sealed and desiccated from release through dispatch. Vials are individually protected for transit. Shipments travel at ambient temperature — appropriate for lyophilized powder, and stated plainly rather than dressed up.

What we will not do

• Publish a purity figure that is not on a certificate.
• Attach one lot's certificate to a different lot.
• Describe a material by what it might do in a person. These are research materials, supplied for laboratory research use only.
