Purity is measured by HPLC (High-Performance Liquid Chromatography), which separates and quantifies each component in a sample. The result is reported as a percentage on the Certificate of Analysis (COA), along with the chromatogram, for every batch.

Yes, we provide certificates of analysis for our products. These documents verify the purity and quality of each batch. You can view all current certificates on our COAs page.

A Certificate of Analysis (COA) is a document that verifies a product's identity, purity, and quality through lab testing. For each batch, it typically includes results like HPLC purity, mass spec identity confirmation, and the corresponding chromatogram.

Each batch gets a unique lot number so its specific COA and test results can be looked up and verified.

All our peptides are tested by independent third-party labs and consistently achieve 99%+ purity. Every product ships with a Certificate of Analysis so you can verify the exact purity of your specific batch.

Peptides ship as lyophilized powder in sealed, labeled glass vials with protective packaging (foam/bubble wrap, insulated mailer) and documentation included. We don't use cold-chain shipping — lyophilized peptides are stable at ambient temperature for short periods, which is standard practice. Store at -20°C or colder immediately upon arrival.

Peptides ship as lyophilized (freeze-dried) powder in sealed glass vials, labeled with product name, lot number, quantity, and storage instructions. Each shipment includes: vials wrapped in foam/bubble wrap for protection; foil-lined or insulated mailers for basic thermal protection; COA and packing slip sealed in a separate envelope. On temperature: we don't offer cold-chain or refrigerated shipping (no ice packs or coolers). This is standard for lyophilized peptides, which are stable at ambient temperature for short periods during transit. Once your order arrives, transfer it to -20°C or colder storage right away.

When stored properly (lyophilized at -20°C), most peptides remain stable for 12-24 months from date of manufacture. Specific expiration or retest dates are provided on the COA for each lot. Stability is influenced by peptide sequence — sequences containing methionine, tryptophan, or cysteine may be more prone to oxidation and have shorter shelf lives. Post-expiration, material should be retested or disposed of according to your laboratory's quality protocols.
