A UK Alternative to The Peptide Code

Researchers often want to read about a compound before deciding whether it belongs in their work, so we publish reference guides alongside the catalogue. Each one explains what a compound is and summarises what the published research reports, with the sources it draws on, and every guide is framed for in-vitro laboratory research use only. Some cover compounds we do not stock, and say so. The compounds we do supply are synthesised at our own UK facility, delivered as pre-mixed liquid vials with a batch Certificate of Analysis, and dispatched the same day for orders placed before 3pm, Monday to Friday. All compounds are supplied strictly for in-vitro laboratory research use only.

Each guide starts from the published literature rather than from the product. It sets out what a compound is, where it appears in the research record and what studies have reported, attributing each point to its source so a reader can check it. A good reference guide also says what kind of evidence it rests on, whether cell work, animal models or studies in people, because a finding means different things in each.

Our guides do not give dosing or administration guidance; where a reader is likely to ask, the guide says so directly. Several cover compounds we do not stock at all, because a clear explanation is useful whether or not we sell the material. Where we do supply a compound, the guide and the product page do different jobs: one explains, the other describes what is in the vial.

Reference pages on supplier websites range from careful summaries to thinly disguised adverts, so a few checks help. Are claims attributed to published sources you could look up yourself? Is it clear whether a finding comes from cell work, animal models or people? Does the page stay within research use, or drift into advice it has no business giving? Would the page still make sense with the product links taken out?

We write our own guides to pass those tests, and we would suggest applying them to every supplier on your shortlist. Reference material that passes them is a reasonable sign that a supplier takes the research framing seriously; material that fails them tells you something too.
