How we document every batch

Every peptide lot we release passes through a documented quality workflow before it is listed for sale. That workflow is designed for researchers who need to verify identity, purity, and consistency—not just read marketing claims on a product page.

Batch assignment at synthesis

Each production run receives a unique batch identifier at the point of lyophilization. That ID follows the vial from fill to final QC release. When you receive an order, the batch on your COA matches the batch recorded in our fulfillment system.

Third-party analytical testing

We use independent laboratories for:

• purity profiling against reference standards
• molecular weight confirmation and identity
• where applicable to the compound class

Results are reviewed against internal release specifications before a lot is approved for distribution.

Public certificates of analysis

Authenticated customers can access the COA for their specific batch from the product page and order history. We publish the analytical data researchers need to validate inputs before experiments begin.

Why this matters for your lab

Reproducible research depends on consistent starting materials. Batch-level documentation lets you cite the exact material used in your methods section and trace any variability back to a documented lot—not an anonymous vial.
