406 Peptides is a Montana-based supplier of research peptides and laboratory materials. We built the company around a simple idea: researchers deserve a clean catalog, clear batch documentation, and straightforward pricing — without account walls, hype, or guesswork.
What we do
We supply high-purity research peptides and related laboratory supplies to qualified researchers and institutions. Every product is intended strictly for in-vitro laboratory and research use. Pricing is shown by size on every product page, and certificates of analysis are posted to our COA library by product and lot as our laboratories provide them.
How we operate

- U.S. fulfillment. Orders are packed and shipped from Montana with tracking.
- Straightforward pricing. Prices are listed by size on every product page. No account is required to view them.
