Lab reportsQuestions,
answered.
How is each batch tested?
Every lot is analyzed by reverse-phase HPLC to confirm identity and purity before release, and is independently tested by a third-party lab. Each lot is traceable to its certificate of analysis.
How do I get a certificate of analysis?
Certificates are available for every lot. Use the link on any product page or the Lab Reports page, and include the lot number printed on your vial.
Where do orders ship from?
All orders ship from the United States, so there are no customs holds or international delays. In-stock items are typically processed within 24 hours; our Shipping page has the details.
How should compounds be stored?
Lyophilized (freeze-dried) peptides should be kept sealed, dry and away from light, ideally refrigerated at 2–8 °C. For long-term storage, keep them at −20 °C.
Are products stable in transit?
Yes. Lyophilized peptides are stable at room temperature for the length of normal shipping. Refrigerate them when they arrive.
