07FAQ
Questions, answered plainly
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 lyophilized powder in a sealed vial. Reconstitution is performed in the laboratory using a suitable solvent such as bacteriostatic or sterile water, added slowly down the vial wall and allowed to dissolve without vigorous shaking. Volume depends on the researcher's intended working concentration. This guidance is provided for laboratory research handling only.
Store lyophilized vials at −20 °C for long-term storage. For short-term storage, 2–8 °C is appropriate. Once reconstituted, keep refrigerated at 2–8 °C and protect from light, and minimize freeze-thaw cycles. 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.

What the research community says
Lot-to-lot consistency is what kept us. The COAs match the HPLC traces we run in-house, so reproducing a prior experiment with a new lot is genuinely predictable.
The Certificate of Analysis covers what I actually need to see — mass spec for identity, HPLC for purity, and endotoxin screening. It's the difference between documentation and a sticker.
Batch-specific COAs and clean documentation make our internal review straightforward. Every lot maps back to a record we can file and audit.
We switched after running into purity issues with a previous supplier. The HPLC results here held up against our own analysis, lot after lot.
The price-to-quality ratio is hard to beat, and the bundle discounts make larger orders for a study budget workable without cutting corners on documentation.
Packaging was professional and secure, the vials arrived intact, and the lot documentation matched the order exactly — with carrier tracking from dispatch to delivery.
