For Research Purposes Only · Not For Human Consumption
How this site's content is written, sourced and corrected.
We sell unlicensed research compounds. That places a higher obligation on us than on an ordinary retailer to be precise about what is known, what is investigational, and what we are not entitled to claim. This page sets out the rules our research library is written against — so you can hold the content to them.

Who is responsible for this content.
Jack Muncaster
Founder, UK Peptides
Jack founded UK Peptides in Manchester after repeatedly receiving research compounds with missing or recycled paperwork. He is responsible for supplier selection, batch release decisions and the content published in this research library. Every article here is sourced to primary literature and every product page to a signed third-party certificate.
admin@uk-peptides.orgWhat we are not. We are not clinicians, and nobody at UK Peptides holds themselves out as medically qualified. Nothing published here is medical advice. Where a factual claim matters, it is carried by the cited primary literature or by a signed third-party certificate — not by our own authority. If you need clinical guidance, speak to a qualified professional.
The standards every article is written against.
- 01
Primary sources, cited inline
Factual claims are referenced to peer-reviewed literature, clinical-trial registry records, or regulatory documents — not to other vendors' blog posts. Every article ends with its source list, linked so you can verify the claim at origin rather than trusting our summary of it.
- 02
No therapeutic or dosing claims
We publish mechanism, pharmacology and handling information for in-vitro research contexts only. We do not publish human dosing protocols, do not describe therapeutic outcomes, and do not present any compound on this site as a treatment. Compounds sold here are unlicensed and unapproved for human use.
- 03
Investigational status stated plainly
Where a compound is investigational — as retatrutide, BPC-157 and most of our catalogue are — the article says so, names the trial phase where one exists, and does not imply approval that has not been granted by the MHRA or any other regulator.
- 04
Analytical claims trace to a certificate
Purity and identity statements correspond to a specific lot and a specific signed certificate from an independent laboratory. We do not quote a purity figure that is not backed by a certificate you can download from the relevant product page.
- 05
Corrections are made in place
If a published claim turns out to be wrong or is superseded by new trial data, the article is corrected and its review date updated. Email the address below with the article and the issue and it will be reviewed.
Where the numbers on our product pages come from.
Purity figures
Every "≥98% HPLC" claim corresponds to a specific lot tested by Janoshik Analytical or Aspen Bioanalytics. The signed certificate for that lot is downloadable from the product page. We do not publish a purity figure without a certificate behind it.
Identity confirmation
Mass-spectrometry identity results are reported as they appear on the certificate, against the compound's published molecular weight. We do not restate or round the analytical lab's figures.
Research descriptions
Mechanism and research-application text describes published in-vitro and preclinical work, cited on the page. It is not a claim that any compound produces those effects in humans.

Found something wrong? Tell us.
Research moves, and we get things wrong like anyone else. If a claim on this site is inaccurate, out of date, or superseded by newer trial data, email the page URL and the issue to admin@uk-peptides.org. Substantiated corrections are made to the article itself and its review date updated — we do not quietly delete pages that turn out to be wrong.
