About SemaxBuy

SemaxBuy supplies research-grade peptides to laboratories, researchers and institutions across the European Union, with Semax and the wider family of regulator peptides first characterised in Russian pharmacology research as our editorial and catalogue focus. We built this site because the market for research peptides is crowded with stores that publish thin, copy-pasted product pages and no real documentation; we set out to do the opposite, putting purity data, batch traceability and the underlying literature at the centre of the product, not as an afterthought.

Why SemaxBuy exists

Most listings for research peptides online reduce a compound to a price and a vague marketing line, with no route back to a primary source for whatever is claimed. That gap matters most for the regulator peptide family — Semax, Selank and their structural relatives — because this is a class of compounds with a genuinely long research record, mostly published outside the English-language literature that dominates search results, and so it is also a class where confident-sounding but unsupported claims travel further than the underlying evidence. We chose to focus narrowly on this family rather than carry a shallow catalogue of everything, so that each product page, guide and article can be built around a specific, citable source rather than a generic template. Our Semax research overview and supporting guides exist to give researchers a single, sourced reference point, with every scientific statement attributed to a cited study rather than presented as a general promise.

How we work

Every batch we list is accompanied by a certificate of analysis covering HPLC purity and mass-spectrometry identity confirmation, issued by an independent laboratory rather than produced in-house — we treat a manufacturer's own internal specification sheet as a starting point, not as proof. Certificates are batch-specific, not a single sheet reused across every shipment, and are available on request before an order is placed, not only after. That link between the batch number printed on a vial and the batch number on its certificate is, in our view, the single most important piece of traceability a buyer can check, and we explain how to do so at /purity. Storage and shipping follow the stability profile of each compound, with packaging designed to preserve the cold chain in transit where the specification requires it. Orders are confirmed in writing before payment and shipped by tracked courier across the United Kingdom, Ireland and the rest of Europe.

What we do not do, and why

We do not give medical advice, and nothing published on this site is intended to inform a personal health decision; our research disclaimer sets this out without ambiguity. We do not make any claim of benefit for a named condition, in a person or an animal, for any product we list. Where we describe a study finding, we name the model used — in vitro, a specific animal model, or a clinical trial population — and we do not extrapolate beyond what that study reports.

We also do not publish product reviews or star ratings, and this is a deliberate policy rather than an oversight. A review of a research reagent cannot be verified the way a review of a consumer product can: there is no way to confirm that a reviewer used the product as a laboratory reagent rather than otherwise, and health-adjacent categories are exactly where manufactured or incentivised social proof causes the most harm. Rather than publish ratings we cannot stand behind, every product page links out to the peer-reviewed literature itself, so a researcher can read the primary source and reach their own conclusion.

Who we serve

Our audience is university and contract-research laboratories, independent researchers, and informed buyers across the European research-chemical market who want a sourced, specific reference rather than marketing copy. If that describes you, our research guides and blog are the best place to start, alongside the frequently asked questions covering purity, shipping and legal status.

How to audit us

We would rather be checked than taken on trust. Before ordering, you can request the certificate of analysis for the specific batch you would receive, by Telegram or email, and compare its stated purity method, issuing laboratory and batch number against what is published at /purity. If a claim on this site is not backed by a citation you can look up yourself, that is a gap we want to know about. Every product referenced on this page is supplied for laboratory research use only.
