Compliance

Testing and compliance

Every product is independently tested, and its certificate of analysis is published where you can read it.

Testing standards

Purity method	High-performance liquid chromatography (HPLC)
Identity check	Mass spectrometry (MS)
Purity standard	99% or higher
Who tests	Independent third-party laboratory
Scope	Documented per batch

Certificates of analysis

A certificate of analysis (CoA) reports the HPLC purity result and the mass-spectrometry identity check for the batch it covers. Certificates are listed here as they are published.

Certificates are being added. Request one below.

Need a certificate that is not listed? Email support@uspeptidescience.com with the compound name, batch number and your order number, or use the contact page.

What a certificate reports

The compound the certificate covers, so you can match it to your vial.
The HPLC purity result for the batch tested.
The mass-spectrometry identity check confirming the molecule.
The batch the result applies to, so it can be traced from the label.

Independent third-party testing

Testing is done by an independent laboratory, not by us, so the results are not ours to grade. Our standard is 99% purity or higher.

Laboratory handling

Handle only in a laboratory setting, with gloves, eye protection and a lab coat.
Follow the storage conditions on the product label. Lyophilized peptides are generally kept cold, dry and out of light.
Keep a record of the batch number from the label so it can be matched to its certificate.
Dispose of unused material according to your institution's chemical waste procedures.
