Our mandate
The Georgian Door publishes educational content for Dublin-based buyers and researchers who want to verify a peptide batch before making any purchase decision. We do not sell products. We do not recommend suppliers by name outside a single, clearly marked page. We do not advise on dosage, therapeutic use, or any application of research compounds in humans. Our editorial focus is narrow and specific: does the Certificate of Analysis in front of you meet the standard of an independently verifiable batch record?
Everything we publish is written to help a Dublin buyer answer that question with more confidence than they had before reading it — for the compounds our readers actually ask about: BPC-157, semaglutide and retatrutide.
What counts as a real COA
The core criterion behind every verification guide we publish is drawn from what accredited analytical chemistry laboratories actually produce. A meaningful Certificate of Analysis satisfies all of the following:
The COA must be issued by a laboratory independent of the seller. An in-house test report produced by the same entity selling the compound does not qualify. Independence is non-negotiable.
We look for accreditation to ISO/IEC 17025 or an equivalent standard. ISO 17025 is the international benchmark for testing and calibration laboratories; accreditation by a recognised national body demonstrates that a lab's methods, equipment and procedures have been independently audited.
The report must state purity percentage by HPLC for the specific lot or batch referenced. A general product specification sheet with no lot number is not a COA — it is marketing copy.
Purity alone doesn't confirm you have the correct compound. We require that a COA also confirm molecular identity via LC-MS, matching the expected molecular weight of the target peptide sequence.
The lot number on the COA must match the lot number on the product you'd actually receive. A COA that can't be traced to a specific batch is unverifiable.
What we do not verify
The Georgian Door does not inspect physical samples. We do not operate a laboratory and we do not independently test compounds. Our editorial work teaches readers how to read and assess a COA that a supplier provides — we do not certify any specific supplier's products as safe, pure, or fit for any purpose.
We also do not publish legal analysis of whether a specific compound is authorised for a specific use in Ireland. For that question, consult Ireland's medicines regulator, the HPRA, or a qualified legal professional — it sits outside our editorial scope.
COA red flags — what signals rejection
Our guides consistently flag the following as ✗ rejected signals that a COA is insufficient:
- No lot number or batch number anywhere on the document.
- Purity stated as a vague range rather than a specific measured value.
- HPLC data with no LC-MS identity confirmation alongside it.
- No named issuing laboratory or accreditation reference.
- Formatting or metadata suggesting the document was edited after issue.
- A "COA" that links back to the seller's own site rather than an external lab record.
A COA passes our editorial threshold — ✓ accepted — only when it satisfies all five criteria above and raises none of the flags listed here.
How we research
The compound information and analytical-chemistry framing in our guides is drawn from:
- Peer-reviewed literature indexed on PubMed, for anything we state about a specific compound's research history.
- Published ISO/IEC 17025 accreditation standards and national accreditation-body registers, for how we assess a laboratory's credibility.
- Publicly available, general information on courier and customs logistics, for anything we say about how a parcel typically reaches a Dublin address.
We do not rely on supplier marketing material as a source, and we do not publish legal analysis of any compound's status — see "What we do not verify" above for where that question belongs instead.
Update cadence and corrections
Every editorial page on this site carries an "Updated" date. If you identify a factual error, contact us at editorial@peptidesdublin.com with the subject line "Correction request" and we will review within 14 days. Confirmed errors are corrected promptly and the page's update date is revised.
What we never publish
As a matter of firm editorial policy, the following does not appear on this site:
- Dosage recommendations or protocols for human use.
- Named supplier reviews or rankings outside the single, clearly labelled
/unlock/page. - Before/after testimonials or anecdotal reports of any compound's effects.
- Claims that any compound treats, prevents, or cures a medical condition.
- Purchase links anywhere except the
/unlock/gate, which is markednoindex,nofollow.
No anonymous authors or invented personas
The Georgian Door publishes under the brand name as an editorial project, not under individual bylines or invented expert personas. We do not fabricate credentials or institutional affiliations. Our authority rests on the sourcing rigour of what we publish, not on a fabricated person with a fabricated CV.
