Peptides are one of the fastest-growing categories in medicine, research, and consumer wellness — and one of the least verified. A single lab test costs hundreds of dollars, takes a week, and tells you about exactly one vial from one supplier. That is not how markets get built. PepiScreen exists because someone had to be the first to look at the whole market at once.
Why this blog exists
PepiScreen is the world’s first independent peptide supplier screening platform. That’s a mouthful, and it’s also a category that didn’t have a name until we gave it one. The blog is where we’ll explain the category itself — the vocabulary, the methodology, the emerging regulation — for buyers, clinicians, researchers, journalists, and suppliers alike.
Expect three kinds of posts here:
- Methodology. How the Proof · Price · Match™ framework actually works. What a Certificate of Analysis really tells you, what it doesn’t, and how to read one without technical training. Why ISO 17025 matters, and what a “verified lab” means in practice.
- Market notes. Patterns we’re seeing across the 750+ suppliers we cross-reference. Regulatory movements in the UK, US, EU, Australia, and Asia. Trends in impurity profiles, common failure modes, and where the compliance frontier is heading.
- Case studies. Anonymised (where necessary) walkthroughs of real supplier evaluations, red flags we found, and how we handled them.
What this blog will not be
Not medical advice. Not a purchase recommendation. Not a place for personal supplier endorsements. Not sponsored content dressed up as editorial. Every claim about a supplier — here or in the directory — is scored by the same evidence engine that runs whether the supplier pays for their review or not. That independence is exactly why a strong PepiScreen score means something.
Membership buys your listing and the verification service — it never buys your score. A paying member can still score Weak Evidence.
Who’s writing
Posts are attributed to PepiScreen as an organisation rather than to individual authors, in keeping with how our directory listings work — the evidence engine is what speaks. Where a specific analyst or methodology change is worth naming, we’ll say so.
