Questions

Everything, on the record.

How do I verify the purity of my vial?+
Every label carries a lot number. Find that lot on our Certificates page and you’ll see the complete third-party Certificate of Analysis — identity, purity, and net content, exactly as the laboratory reported it.
What does 99% purity guaranteed actually mean?+
Every compound we sell is verified at 99% purity or higher by independent HPLC analysis before it’s listed. If a vial ever fails to match its published COA, we replace it or refund it.
Who tests your compounds?+
An unaffiliated, U.S.-based analytical laboratory. We never self-grade: no lot reaches our shelf without an independent report, and that report is what we publish.
How are orders shipped?+
We offer FedEx Express 2-Day cold shipping with refrigerated, temperature-controlled pickup. Standard fulfillment days are Monday–Friday, excluding holidays. Transit starts after dispatch; processing time is separate. Orders over $250 ship free. See our Shipping page for details.
Who can purchase?+
Qualified researchers and institutions, 21 or older. Everything we sell is strictly For Research Use Only — laboratory reagents for in-vitro research, not for human or animal use of any kind.
What if something arrives damaged?+
Contact us with your order number and photos of the packaging and affected items. Optional transit-protection coverage requires purchase with your order and is subject to its terms and claim approval. Without purchased protection, discretionary transit replacements or refunds are not offered. Incorrect or nonconforming goods and rights required by law are handled separately. See our returns and refunds policy.
