About Sigma Compounds

What we supply

Sigma Compounds supplies research compounds to laboratories and research professionals in the United States: 70 products across lyophilized vials and mists. Everything on this site is sold for laboratory and research use only.

What a listing tells you

Each title carries the compound, the quantity and the form, so two products that share a compound and a dose cannot be mistaken for one another. Stock is shown as it stands, and when something is out you can join the waitlist rather than guess when it returns. Our compounds are third-party tested.

Ordering and support

Orders placed and paid before 12PM PST ship the same business day, Monday to Friday, and shipping is free on every order with no minimum. If something is wrong, write to support@sigmacompounds.com with your order number.
