Questions

What does research use only mean?
Every compound we supply is an analytical-grade biochemical reference standard intended strictly for in vitro laboratory research. These products are not for human consumption. They are not a drug, food, supplement, or medical device, have not been evaluated by the U.S. Food and Drug Administration, and are not for human or veterinary use, diagnostic use, or therapeutic use.
Who do you supply?
We supply qualified researchers and institutional buyers: academic institutions, biotech companies, contract research organizations (CROs), and analytical laboratories. Purchasers must be at least 21 years of age and confirm that material is for in vitro laboratory research only.
How is purity verified?
Every lot is assayed by HPLC at an independent, accredited third-party laboratory. We publish the resulting Certificate of Analysis and link it to the lot number printed on the vial.
Where do I find the Certificate of Analysis?
Every lot has a public, batch-linked COA. Browse them all on the COA page, or open any product page and use the COA tab for that specific compound.
How quickly do orders ship?
Orders placed before 2PM EST ship the same business day. Shipments are cold-packed where required and fully tracked.
Do you ship internationally?
We currently ship within the United States. Requests from institutional buyers outside the US are handled case by case, so contact us before ordering.
