Testing Standards & COA Verification Process
How Vertex Labs arranges independent lot testing, applies its purity standard, and makes laboratory documentation available for review.
Last Updated:
Every lot is submitted for third-party testing before it becomes available for sale. Our sampling practice is one vial for every 100 vials, and our minimum reported purity requirement is 99.0% for materials evaluated by a purity assay.
Vertex commissions independent laboratory testing and does not use manufacturer-provided COAs as its verification documentation. Results apply to the submitted samples and the tests identified in the corresponding report.
1. Purpose and scope
This page describes the purity-testing and Certificate of Analysis verification process used by Greenrock Investment Group LLC, doing business as Vertex Labs (“Vertex,” “we,” “us,” or “our”), for materials offered through vertexpeptideslab.org.
Our documentation is provided to help researchers review the analytical evidence associated with a particular lot. Read the complete laboratory report, including its methods, dates, sample identification, and limitations.
All Vertex products are supplied for lawful laboratory and non-clinical research use only. A COA does not authorize human, veterinary, therapeutic, diagnostic, clinical, or personal use.
2. Independent testing before availability
Vertex submits samples from every lot to a third-party laboratory before making that lot available on the website. We obtain and review the resulting laboratory documentation as part of that process.
We do not substitute a manufacturer’s or supplier’s certificate for the independent testing we commission. The laboratory responsible for a report is identified on that report.
A report for a different lot does not verify a newly received lot, even when the product name is the same. The relevant evidence is the report associated with the lot being reviewed.
3. Lot sampling
Our sampling practice is to submit one vial for every 100 vials in a lot. Every lot is subject to testing before availability.
This is a sampling process. It does not mean that every individual vial undergoes a separate laboratory analysis. The reported results describe the samples received and examined by the laboratory under its stated conditions.
A sample result should be read within that scope. Sampling alone does not establish that every vial is identical or that every possible characteristic of the lot has been measured.
4. Minimum purity standard
For peptides and other research compounds evaluated by a purity assay, Vertex’s minimum acceptance criterion is a reported purity of 99.0%. This is Vertex’s own acceptance standard, not a statement of regulatory approval or a universal laboratory requirement.
The percentage must be interpreted using the material, analytical method, and reporting basis identified by the laboratory. For a blend or formulated research solution, review what the report actually evaluates; do not assume that a single percentage separately characterizes every component.
If a lot fails our minimum purity requirement, the entire lot is rejected and discarded rather than made available for sale.
Meeting the purity criterion addresses that analytical result. It does not establish that the material is suitable for every research procedure or that tests outside the report’s scope have been performed.
5. Methods and interpretation
Our published documentation includes chromatographic purity analysis, such as high-performance liquid chromatography with ultraviolet detection (HPLC-UV). The specific method is the one identified in the applicable laboratory report.
Review the reported purity together with any chromatogram, method description, laboratory comments, and qualifications supplied in that document. A general reference to HPLC or another technique on the website does not establish that every available laboratory test was performed on every lot.
Purity is an analytical result under the stated test conditions. It is not a complete assessment of every possible contaminant, biological effect, or handling risk. Questions about a report’s methodology or interpretation can be directed to Vertex for clarification with the issuing laboratory.
6. Current testing scope and planned additions
As of the date above, Vertex does not provide separate lot-specific reports for sterility, bacterial endotoxins, heavy metals, or residual solvents. These tests are not part of the current documented testing program described on this page.
A purity result does not establish that any of those separate tests has been completed. Descriptions such as “third-party tested” and “COA available” refer to the analyses actually documented for the relevant lot.
We plan to expand the testing program to include these additional analyses. A planned addition is not a completed test, and no implementation date is promised here. Any expanded coverage will be identified through the applicable lot-specific reports and an updated description of our testing process.
Future testing of a new lot will not retroactively verify an earlier lot.
7. How to verify your COA
- Locate the lot number. Read it directly from the product labeling and retain it with your research records.
- Open the COA directory. Visit Certificates of Analysis and search for the product or lot.
- Open the complete report. Compare the product identification and lot number in the PDF with the product you are reviewing. Do not rely solely on the directory heading or filename.
- Review the laboratory information. Check the issuing laboratory, report or accession number, report date, and any verification instructions included in the document.
- Read the purity result in context. Review the stated method, supporting analytical information, and limitations.
- Ask about any discrepancy. If the lot does not match, a document is missing, or information is unclear, contact Vertex before relying on that report for your research.
If you are reviewing documentation before ordering and need to know which lot is currently available, contact us for confirmation. The presence of a report in the directory does not, by itself, establish that its lot is currently in stock.
8. Report authenticity and document corrections
Use the complete laboratory-issued document when evaluating a lot. A cropped screenshot, promotional badge, or summary is not a substitute for reviewing the report and its qualifications.
Where a laboratory provides a report-search code, QR code, or other authentication method, follow the instructions supplied by that laboratory. Verification features vary, and not every report includes an online lookup.
If a report appears inconsistent or requires correction, contact Vertex so we can seek clarification from the issuing laboratory. An analytical correction must come from that laboratory. Website text does not alter the underlying laboratory findings.
The existence of a COA alone does not establish that a laboratory or method holds a particular accreditation. Any accreditation claim must be supported separately by the laboratory’s current credentials and relevant scope.
9. Documentation questions and quality concerns
Email info@vertexpeptideslab.org if you cannot locate a matching report or have a concern about the documentation or material received.
Please include:
- The product name and lot number exactly as shown on the label.
- Your order number, if the question concerns a purchase.
- The report number, document link, or relevant page.
- A description of the concern and a clear label photograph, when safely available.
We will review the available records and seek laboratory clarification when needed. Do not rely on a report for a different lot to resolve missing or inconsistent documentation.
Keep material with an unresolved identification or quality concern separate from material being used in your research until the issue has been assessed. Do not undertake an unsafe procedure or prohibited use to establish a concern.
Order-related remedies are addressed in our Refund, Returns & Cancellation Policy. This page does not remove an applicable warranty, express product commitment, or right that cannot lawfully be waived.
10. Research-use limitations
Independent testing and a satisfactory purity result do not establish clinical safety, suitability for administration, or approval by the U.S. Food and Drug Administration.
Vertex products are not offered for human consumption, veterinary use, therapeutic use, diagnosis, clinical treatment, or personal use. We do not provide medical advice, dosing recommendations, or administration instructions.
Researchers must evaluate whether the documented analytical scope is appropriate for their proposed lawful laboratory work and apply suitable handling, storage, and institutional safety procedures.
11. Updates to this page
We may update this page when our sampling procedures, testing scope, documentation process, or purity standard changes. The effective and last-updated dates identify the version presented here.
A later policy revision does not change the results recorded in an earlier laboratory report or retroactively establish that additional tests were performed. Specific commitments made for an accepted order remain subject to their terms and applicable law.
