The documentation-first research supplier.
KB2 Research supplies reference-grade peptides to professional research organizations — third-party tested, documented to the lot, and dispatched from the US in 1–2 business days.
We would rather be precise about a handful of facts than expansive about qualities that are difficult to substantiate.
KB2 Research sells research peptides to professional research organizations. Every lot is third-party tested, a certificate of analysis is available on request, and orders ship from the US in 1–2 business days. No customer counts, testimonials, awards, or reviews — those are not the basis on which a research supplier should be evaluated.
Built for research organizations.
Who we sell to
Exclusively professional research organizations — laboratories, contract research entities, and institutional buyers conducting in vitro or non-human research. Never for personal, therapeutic, or veterinary use.
A focused catalog
We carry a limited catalog rather than trying to be a general-purpose supplier — so we can hold sourcing, documentation, and fulfillment consistency for what we do carry. If a compound isn’t listed, we can’t currently supply it.
Concrete commitments, not adjectives.
Five verifiable things a skeptical buyer — a principal investigator, a lab manager, a researcher ordering for a group — can evaluate instead of a list of qualities.
Third-party testing
Materials are tested by an independent laboratory — not internal QC alone. The party selling the material is not the party verifying it.
Certificate of analysis, per lot
A COA is available for each lot, so you review the testing data tied to the material you received — not a generic spec sheet. Request and retain the COA for your order.
Purity, where verified
Where testing verifies it, materials meet or exceed 99% purity. We report “≥99% where verified” — the honest number is the one on that lot’s COA, not a marketing average.
US-based fulfillment
Orders ship from within the United States — predictable lead times, and none of the customs uncertainty of international laboratory shipments.
1–2 business day shipping
Once an order is placed and cleared for fulfillment, it ships within one to two business days.
Account first, then a standard store.
Purchasing requires a registered account — not a formality, but how we manage who we sell to. After that, it works like any commercial store.
Register your organization
Account creation asks for your organization’s name and a description of its research use. Both are required before checkout — it’s how we confirm an order is placed by a research organization for research purposes.
Browse & build your cart
Ordering works like a standard commercial store. Every product page states the compound, its presentation and vial size, and its testing and purity framing.
Check out & track
Confirmation and shipment notifications go to the email on your account. We may decline or cancel an order where we can’t confirm it’s consistent with research use.
