Do you ship internationally?

Currently, we ship within the United States only. International shipping is being evaluated and may be available in the future.

How are products packaged for shipping?

All products are shipped in insulated packaging with cold packs to maintain stability. Lyophilized peptides are stable at ambient temperature for short periods, but we take extra precautions to ensure product integrity during transit.

Quality & Testing

How do you verify product purity?

Every batch undergoes independent third-party testing using High-Performance Liquid Chromatography (HPLC) for purity analysis and Mass Spectrometry (MS) for identity confirmation. We require ≥99% purity for all products.

Where can I find Certificates of Analysis?

COAs are available on each product page and on our dedicated View COAs page. Every COA is batch-linked and includes HPLC chromatograms, MS data, test date, lot number, and the testing laboratory’s information.

Who performs your third-party testing?

We partner with accredited analytical laboratories that specialize in peptide characterization. These labs are independent of our manufacturing process, ensuring unbiased results.

Storage & Handling

How should these materials be stored?

Lyophilized (freeze-dried) reference materials should be stored at -20°C for long-term storage. For short-term laboratory use, 2-8°C is acceptable. Storage guidance is provided per lot on the certificate of analysis.

Returns & Refunds

What is your return policy?

Due to the nature of our products and strict quality requirements, we cannot accept returns on opened products. Unopened products in original packaging may be returned within 14 days of delivery for a full refund.

What if I receive a damaged product?

If your order arrives damaged, contact our support team within 48 hours of delivery with photos of the damage. We will replace the product or issue a full refund at no additional cost.
