Refund & Replacement Policy

Due to the strict sterile and temperature controls required for the storage of lyophilized peptide research compounds, we do not accept returns or exchanges for items that have left our shipping chain custody.

This policy is strictly enforced to guarantee the chemical integrity and sterility of compounds delivered to other laboratory clients.

Every batch supplied by 99 Purity Wholesale is guaranteed at a purity of ≥99% as validated by independent third-party laboratories.

In the event that an independent, certified laboratory analysis (utilizing validated HPLC/MS techniques) shows that a supplied compound has a purity of less than 99%, we will issue a full replacement or store credit. Supporting chromatogram documentation must be provided for all quality claims.

We take extreme care in packaging bulk glassware and vial kits. However, if transit damage occurs:

• Any broken vials or kit damages must be reported to our operations desk within 48 hours of delivery.
• Reports must include photographic evidence of the unopened packaging and damaged contents.
• Upon verification, replacements will be shipped immediately via priority dispatch at no additional cost.

Orders can be cancelled for a full refund at any time prior to shipping label generation.

Once a shipment has been processed and entered the carrier network, the transaction is final and cannot be recalled or cancelled.

To submit a quality or transit claim, please email our laboratory operations desk at wholesale@99puritypeptides.com with your order invoice number, batch/lot tracking code, and any supporting HPLC chromatograms or photos.
