A small shop
in Patterson.

Patterson Peptides is a small research supply company in Patterson, California. We sell research materials to people doing in vitro and laboratory work, and that is the whole business.

We keep the catalog short on purpose. Every listing tells you what the material is, how much is in the vial, whether we have it, and what it costs. You will not find claims here about what anything does to a body, because that is not what we sell it for and it is not ours to say. Nothing on this site is medical advice.

Your side of it

Once it leaves us, the work is yours. You decide whether a material suits your experiment, you store and handle it safely, and you follow whatever rules apply where you are: your lab, your institution, your local ones. These materials belong in the hands of people trained to work with them.
