Third-party tested. COA available on request: email shari@usprimebiolabs.com with the product name and lot number. The Quality page explains what each test measures.
What does a certificate of analysis show?
Identity by mass spectrometry, purity by HPLC and the measured content of the vial, for one production lot. To get the certificate for your lot, email us the lot number from the vial label or packing slip.
How do I get the certificate for my vial?
Email shari@usprimebiolabs.com with the product name and the lot number, and your order number if you have it. We reply with the certificate for that lot.
Where is my lot number?
The lot number is printed on the vial label and on the packing slip that comes with your order. It ties your vial to its production run and its certificate.
How are products made?
Products are manufactured under documented quality control and third-party tested, with a certificate of analysis available on request. Each vial carries its lot number, which ties it to its production run and its certificate.

Products
How are products supplied?
Peptides are supplied as lyophilized (freeze-dried) powder in sealed vials. Sprays, dissolving strips and lab supplies are listed in their own categories, and each product page gives the form and storage conditions.
How should products be stored?
Each product page gives the storage conditions for that product. Most lyophilized peptides are listed at −20 °C, desiccated, and some also need protecting from light. Keep vials sealed until they are needed, and avoid repeated warming and cooling.
Do you give instructions for use?
No. These are research materials for laboratory use only. This site gives no instructions for use, and we do not answer questions asking for them.
