What the research community says

07 FAQ

Your questions, answered

The details that matter before you order: purity, documentation, handling, and delivery.

How is purity verified, and what does 99%+ actually mean?

Every lot is analyzed by reverse-phase HPLC, which separates the target compound from related impurities and reports the target as a percentage of total peptide content. “99%+” means the documented purity on that lot's Certificate of Analysis is at least 99%, quantified against a reference standard — not an estimate or a marketing figure.

What is a Certificate of Analysis (COA)?

A COA is the analytical record for a specific production lot. Ours document HPLC purity, mass-spectrometry identity confirmation, and endotoxin screening, each performed by an accredited third-party laboratory. A COA accompanies every order and every lot is archived in our public COA library.

How do I reconstitute a lyophilized peptide?

Our compounds ship as lyophilized (freeze-dried) powder. Reconstitution volume and diluent depend on your protocol and the compound. This is a laboratory procedure to be determined by the qualified researcher; we provide the compound, its purity data, and handling notes, but no dosing or in-vivo guidance.

How should peptides be stored?

Lyophilized peptides are generally stored cold and protected from light and moisture; reconstituted material is typically kept refrigerated and used within a defined window. Follow your institution's protocols. Every order ships with storage-and-handling notes for laboratory use.

How fast do you ship?

Orders placed before 2 PM ET dispatch the same business day from our US facility, with carrier tracking and shipment protection on every order. Free shipping applies to orders over $200.
