Frequently asked questions

These materials are supplied strictly for laboratory research — method development, analytical characterization, and in-vitro or similar controlled scientific work. They are not drugs, supplements, foods, or cosmetics, and are not intended for human or veterinary use, or for diagnosing, treating, curing, or preventing anything. Purchasing confirms you'll use them only in that research context and in compliance with the laws of your jurisdiction.

It permits laboratory research use by someone qualified to handle research chemicals in an appropriate setting. It does not permit any use in or on humans or animals. We can't advise on what your specific institution or jurisdiction allows — that's yours to confirm before ordering.

A per-lot Certificate of Analysis is an independent laboratory report for the specific production lot you'd receive. Many suppliers post one "representative" report and reuse it across every batch. We publish a fresh third-party COA for each lot and replace it when a new lot arrives.

Find the lot number on the vial label and enter it in the Lot Lookup field (site header, homepage, footer, and every product page). You'll get the same COA we hold on file. If a number returns nothing, stop and contact us so we can verify it against our records.

Identity confirmation, purity (with method), mass / net quantity per vial, the lot number, and the testing laboratory and date. Methods referenced include HPLC for purity and mass spectrometry for identity. Endotoxin, heavy metals, and bioburden require a second laboratory and are shown as pending until one reports them.

Always per vial. Every mass on this site — including each component inside a multi-component preparation — is stated per vial. We never quote "per kit."

Yes. Each multi-component preparation lists every sequence and its mass per vial, and the total mass per vial. We use plain descriptive names based on contents, not proprietary or supplier blend names. Where a per-component split is not fixed on the supplier documentation, we say the value is reported on the lot certificate rather than estimating it.

No. We describe identity, purity, mass, and provenance — nothing about effects, outcomes, or uses beyond research characterization. Where peer-reviewed literature exists, we may neutrally note that it is publicly available. That is never a representation of a benefit.

General handling guidance for lyophilized research peptides is to keep vials cold and protected from light and moisture; many labs store lyophilized material frozen and minimize freeze–thaw cycles. Treat this as general laboratory handling information, not a specification. We do not provide reconstitution-for-use instructions, as these materials are not for human or veterinary use.

Checkout submits a non-binding order request. We reply by email to confirm the compounds, quantities, lots, and total, and payment instructions follow that confirmation. No card details are collected on this site and nothing is charged when you submit the request.

Because these are research materials whose integrity depends on handling and cold chain, all sales are final once dispatched. We stand behind order accuracy and transit integrity — contact us promptly about any order that arrives damaged, mislabeled, or that fails to match its COA.

Don't use the material as identified. Contact us with the lot number and a photo of the label, and we'll verify it against our records or replace the item. A lot number that returns no report is exactly the situation lot lookup exists to catch.

Yes. We support purchase orders, formal quotes, W-9 documentation, and net terms on approval. Start at Institutional Ordering or contact us with your compounds, quantities, destination, and PO/AP contact.

Published quantity breaks apply at 3, 5, and 10 vials. Beyond that, volume and bulk are quoted per order through the institutional channel — send the compounds, quantities, and destination and we'll return a quote.
