What is on this site
There are three kinds of page. Peptide briefings, 15 of them, run from licensed incretin medicines such as semaglutide to compounds known only from rat studies such as BPC-157. Each one follows the same order: how the peptide works, an evidence ladder, the doses that published studies report, safety findings, bench notes, its status in the three countries, and how to check what you order.
Guides deal with the practical side: ordering within the Benelux, reading a certificate of analysis, storage and reconstitution, and comparisons within the larger classes. The research blog adds one article a day.
How we treat evidence
The same sentence can describe a cell culture, a rat, twelve volunteers or four thousand trial participants, and it means something different each time. So every claim here names its level. When a body of work rests on one laboratory, we say which one. When human data do not exist, we say that instead of borrowing confidence from animal results.
Numbers are handled the same way. A dose on this site is one that a published study or a licensed product actually used, and the text says which. You will find no directions for use in people here, and no page should be read as medical advice. A figure we cannot trace is a figure we leave out.
Our relationship with King Peptides
Every order link on PeptidenBenelux.com goes to King Peptides (kingpeptides.nl). This is a commercial relationship. The links carry a referral code, and when someone orders through them the site receives a payment from the shop. You pay nothing extra. That income is what keeps the site running, and it is the reason we do not describe ourselves as a neutral third party.
What it does not buy is a kinder reading of the literature. A peptide with no human trials is described that way whether or not the shop sells it. Where the shop does not list a peptide, the page names the closest product and states that it is a different compound.
Our statements about the shop stop at what the shop itself publishes. Its lab reports page lists every product at 98% HPLC purity or better, most of them at 99% or better. Each lot comes with its own certificate, carrying an HPLC trace and a mass spectrum, and parcels are sent from the Netherlands. Prices, stock and terms of sale appear only on the shop’s own pages, where they are current.
Delivery in the three countries
Parcels leave the Netherlands with tracking. Inside the Netherlands delivery usually takes one or two business days; for Belgium, Luxembourg and the rest of the EU the shop allows three to five. Nothing passes customs on the way, because all three countries are inside the EU. The Benelux buying guide covers what arrives and what to check first.
Why English
Laboratories and universities in the Benelux work largely in English, with staff and students from many countries. The language menu in the header offers Dutch, French and German through machine translation. It helps with reading along; for anything that matters, rely on the English text.
How the blog is made
An AI writing system based on Claude prepares the daily article from the knowledge base behind the briefings and from published papers. Software then tests length, layout, links and the required disclosures, and only a draft that clears those tests is published. Briefings and guides go through a separate round of writing and checking. Spotted an error? The contact page at kingpeptides.nl reaches us, and we fix what is wrong.
