Frequently Asked Questions

We are proud to support laboratories and research professionals who prioritize quality and consistency.

Are your peptides tested for purity?

Yes. Every batch undergoes independent third-party laboratory testing to verify purity, identity, and molecular integrity. A Certificate of Analysis is provided for transparency when available for the relevant batch, including HPLC and mass spectrometry data where listed. We are committed to delivering consistently verified research materials.

No. All products sold on our website are strictly intended for laboratory research purposes only. They are not approved for human consumption, medical use, or therapeutic application. By purchasing, customers confirm they are qualified professionals conducting authorized research.

Sealed research materials should be stored in controlled conditions according to the product label, batch documentation, and laboratory SOPs. Avoid unnecessary heat exposure, moisture, direct sunlight, and repeated temperature swings.

Yes. We provide batch-specific Certificates of Analysis for transparency when available for the relevant lot. Each report may include purity percentage, analytical testing results, and batch verification details. Researchers can review available documentation on the Certificate of Analysis / Batch Verification page or contact Peptignite with the batch number.
