Every batch. Every time.
Our quality process is built around three principles: independent testing, full documentation, and a clear pass/fail gate before any batch is released to the catalog.
The testing protocol
Every incoming batch is submitted through a multi-panel quality workflow managed through an independent laboratory process. Results are reviewed against reference specifications before a batch is cleared for the catalog.
Identity (MS)
Mass-spectrometry confirmation of molecular identity. Measured molecular weight is matched against the reference spectra for each compound.
Purity (HPLC)
High-performance liquid chromatography quantifies purity. Peak area and retention time data are recorded as part of the batch record.
Sterility
Sterility screening is applied where the product format requires it. Bacteriostatic aqueous products are tested for preservative integrity.
Heavy Metals
Inductively coupled plasma (ICP) screening for heavy-metal content where applicable to the compound and intended research use.
Endotoxins
LAL endotoxin testing on aqueous and reconstitution-ready products, where applicable to the product format.
Documentation
Every batch is logged with a unique identifier and a full test record is archived for future reference. COAs are available on request.
The pass/fail gate
A batch is released to the catalog only when all applicable panels return results within specification. Any batch that fails identity, purity, or applicable sterility/endotoxin screening is rejected and does not ship. Rejected batches are documented internally.
Batch records
Every production batch is assigned a unique batch identifier at receipt, and all test results are archived against that identifier. Customers can request the Certificate of Analysis for any batch by contacting quality@pepvee.com with the batch number from their order.
Cold-chain logistics
Temperature-sensitive products are packaged and shipped using cold-chain logistics designed to preserve compound integrity from facility to laboratory bench. Ice-pack or gel-pack configurations are chosen based on product stability profile and transit time.
