About — Peptide Data

Editorial independence

We do not sell peptides. We do not run a clinic. We do not accept payment from vendors in exchange for editorial coverage — ever. This is not aspirational, it is structural: the moment we became a shopfront, we would stop being useful.

We do generate revenue from a small number of affiliate partnerships with vendors who have independently passed our review process. These partnerships are disclosed on every page they affect. They do not influence our ratings, our writing, or the order in which vendors appear in our tables. We will publish negative reviews of affiliate partners, and we have.

How we research

Peptide Data is compiled with the help of an automated research agent. For each compound the agent surveys the published literature — PubMed, MHRA classifications, clinical-trial registries, and vendor certificates of analysis — and drafts a profile graded against the evidence base below. Every draft is then read and signed off by a human editorial lead before it goes live. The agent handles the volume; the editor owns the judgement.

This is a research reference, not a prescriber. The compounds covered here are studied in preclinical and published research and are not licensed medicines in the UK. Nothing on this site is an instruction to self-administer.

How we grade evidence

Every compound profile carries one of four evidence grades, applied consistently:

Strong Multiple high-quality randomised controlled trials in humans, with consistent and clinically meaningful results.
Moderate Either consistent animal evidence plus limited human data, or single-trial human evidence awaiting replication.
Limited Mechanistic plausibility and animal data only, or single small uncontrolled human studies.
Anecdotal Practitioner reports and forum-derived information only. No formal evidence base.

How we rate vendors

We buy our own samples — vendors do not know they are being tested. Samples are sent to an independent ISO-accredited UK analytical lab. Vendors are scored on purity, certificate-of-analysis quality, shipping integrity, customer service, and price per verified milligram. Full methodology is published; ratings are refreshed quarterly.

Our regulatory framing

Peptide Data is written for a UK audience. We frame everything in current UK law and MHRA guidance. Where US references would discuss FDA scheduling or DEA classification, we discuss the Medicines Act, the Human Medicines Regulations 2012, and the Misuse of Drugs Act 1971. Research peptides are not licensed medicines in the UK and are not for human consumption. We say this once, clearly, and move on.
