How can I access a Certificate of Analysis (COA)?
Batch-specific COAs are available directly through individual product pages and through the COA Vault. Match the batch number on your vial to the corresponding batch number listed on the COA to review the applicable testing documentation.
What is a batch number?
A batch number is a unique identifier assigned to a specific production batch of a compound. Batch numbers are used to associate products with their corresponding Certificates of Analysis (COAs), analytical testing data, and production records for traceability and verification purposes.
Please note that some laboratories may use the term “lot number” instead of “batch number.” These terms are used interchangeably and refer to the same production identification system.
The lyophilized powder in my vial appears clumped or chunked. Is this normal?
Yes, this is completely normal and expected. Lyophilized material may naturally vary in appearance between vials and can form small chunks, compact structures, or uneven powder formations as the material shifts and settles within the vial. This does not indicate an issue with the material or its quality.
Does Peptico accept returns?
No. Due to the nature of research-use materials, all sales are final and products are not eligible for return. Peptico products are intended for research use only.
