Purity You Can Verify, Not Just Trust.

Each lot is analyzed by an independent laboratory using reverse-phase HPLC to quantify the target compound as a percentage of total peak area. A result of 99%+ means the lot's chromatogram shows the target peptide at or above 99% purity. Identity is separately confirmed by mass spectrometry. Both results are recorded on the lot-specific Certificate of Analysis.

A Certificate of Analysis is a third-party analytical report tied to a specific lot number. It documents the measured purity (HPLC), confirmed identity (mass spectrometry), and screening results such as bacterial endotoxin. Because it is lot-specific, it lets you verify exactly what was tested for the material you received rather than relying on a generic product claim.

Compounds ship as a lyophilized powder in a sealed, tamper-evident vial, labelled with the lot number that matches its published Certificate of Analysis. Lyophilized material is stable at ambient temperature in transit, so no temperature-controlled shipping is used or required.

Store lyophilized vials at −20 °C for long-term storage. For short-term storage, 2–8 °C is appropriate. Keep vials sealed, protect from light and moisture, and avoid repeated temperature cycling. These are factual storage parameters for the researcher; follow your institution's protocols.

In-stock orders are processed and shipped the same day when placed before the daily cutoff. Every shipment includes carrier tracking and shipment protection, and your tracking number is emailed at dispatch so you can follow the order from our facility to delivery.
