Tidewater Peptides is a small research supply company in San Clemente, California. We sell lyophilized peptide sample vials and the lab essentials that go with them, for researchers who want small quantities handled with care.
Why sample vials
Most research starts small. A single 2 mg or 5 mg vial lets a lab qualify a material, run a pilot or check a method before committing to larger stock. We keep the catalog focused and the vial sizes small, so pricing stays simple and every order gets the same attention.

How we work
- Every lot is logged on arrival and given a Tidewater lot number before it is shelved.
- Peptide stock is held frozen at -20 °C and protected from light.
- Each vial and carton is labeled with its lot number, quantity and research use statement.
- Orders are packed cold and shipped Monday to Wednesday.
- A certificate of analysis is available on request for every lot we sell.
Who we serve
University labs, independent researchers and contract research teams across the United States. Buyers confirm they are 21 or older and purchasing for laboratory research before they order.
