For the record

Asked often. Answered plainly.

What gets tested, how an order ships, and what research use only means.

Where can I read the testing report?
Available supplier-issued certificates of analysis appear on the product page and in Testing & COAs. Match the product, size and lot number, then read the testing methods and results on the report. A missing certificate is marked pending.
What does “research use only” mean?
All products are sold strictly for laboratory and research use. They are not for human or animal consumption, and no therapeutic, diagnostic, or dosing claims are made. You must be 18 or older to order.
How fast do you ship?
Orders ship 2-day express in plain, protective, unbranded packaging, typically dispatched the same business day when placed before 2pm PT. Free 2-day express on research orders over $200; a flat rate applies below that.
How is my order packaged?
Discreetly, in plain unbranded outer packaging with no product names on the exterior. Lyophilized vials are stable in transit; store per your research protocol on arrival.
What if my order arrives damaged?
Email us within seven days with photos and your order number. Damage that clearly occurred in transit is replaced at our discretion. See the returns policy for full details.
Where are the products made?
Produced domestically in the USA, never overseas, and verified to one standard across the catalog.
