Questions about a lot, a certificate, or an order? We reply within one business day.
Yes. Every lot is analyzed by an independent laboratory using HPLC and mass spectrometry. The certificate of analysis is linked on each product page.
Everything we sell is supplied as a reference material for in-vitro laboratory research. It is not a drug, food, cosmetic or dietary supplement, and is not intended for human or veterinary use. We cannot advise on dosing, administration or effects.
Orders placed before 2 pm on a business day usually ship the same day. Delivery typically takes 2-5 business days.
Unopened, sealed items can be returned within 14 days of delivery. Because these are laboratory reference materials, opened vials cannot be accepted back. See the Return Policy for details.
