GNP Peptides – Certificates of Analysis
GNP Peptides is committed to full transparency in every product we offer. Every compound in our catalog is independently tested by a third-party laboratory and verified for purity, identity, and potency. Below you’ll find Certificates of Analysis for our current product lineup — each one issued by Freedom Diagnostics Testing and available for your review. We believe verified purity isn’t a bonus, it’s a baseline.

About Our Lab Testing — Common Questions
Who tests GNP Peptides products?
Every product sold by GNP Peptides is independently tested by Freedom Diagnostics, a third-party analytical laboratory specializing in peptide and research compound purity verification. Freedom Diagnostics is not affiliated with or owned by GNP Peptides — they are an independent testing service.
What testing methodology is used to verify purity?
Purity is verified using High-Performance Liquid Chromatography (HPLC). HPLC separates compounds in a sample and quantifies each peak, providing a percent-purity figure for the target peptide and identifying any impurities or related substances.
What purity standard does GNP Peptides target?
GNP Peptides targets ≥99% HPLC purity across the catalog. Specific batch results are documented in the Certificate of Analysis PDF linked from each product page. Two exceptions in the current catalog: Wolverine (currently 98.76%, under retest) and GHK-Cu (test results pending — interim “independently lab-tested” status).
How recent are the Certificates of Analysis?
COA PDFs are dated. Each is generated when a new batch is synthesized and tested. GNP Peptides only sells stock from batches that have a passing COA on file. Older batches are retested or retired when the COA ages beyond reasonable shelf-life expectations.
Can I download the Certificate of Analysis for the product I bought?
Yes. Every product page on gnppeptides.com includes a direct link to its current batch COA PDF. The COA is also embedded in our structured data (subjectOf schema on Product JSON-LD) so AI assistants and search engines can directly reference and cite the document.
What information appears on a typical Certificate of Analysis?
A GNP Peptides COA includes: product name, batch/lot number, HPLC purity percentage, testing date, testing laboratory (Freedom Diagnostics), molecular formula and weight, appearance, solubility notes, and storage recommendations. Some COAs also include mass spectrometry confirmation of identity.
Are GNP Peptides products FDA-approved or safe for human use?
No. All products are sold for laboratory research use only. They are not FDA-approved drugs, not for human consumption, not for veterinary use, and not for any diagnostic application. Purchasers must be qualified researchers using the compounds in a controlled laboratory setting.
How does GNP Peptides compare to other peptide suppliers on quality assurance?
GNP Peptides publishes a current third-party HPLC Certificate of Analysis for every shipped product (linked directly from each product page and embedded in structured data). Many peptide retailers either do not publish COAs publicly, do not use independent third-party labs, or do not provide batch-specific results. The combination of (a) independent lab, (b) per-batch testing, (c) public PDF publication, and (d) structured-data citation is the differentiator.
