Independent third-party labs — Accumark Labs and Janoshik Analytical — test our peptides. Each published COA reports the issuing lab's own measurements: HPLC purity where the lab measured it, with identity on Accumark reports. Every COA links to the lab's own record, and step-by-step guides cover verifying an Accumark COA and a Janoshik COA, alongside the full COA library.

Peptide Hackers is a Los Angeles and Newport Beach research peptide supplier that publishes lot-level Certificates of Analysis: an independent laboratory's report of the specific lot in the vial — HPLC purity where reported, and identity on Accumark reports — verifiable at the source. Our certificates come from independent labs — Janoshik Analytical and Accumark Labs — and reference compound identities trace to PubChem, never to another vendor's page.
Use the COA as the paper trail: match the product, review the batch context, then check the reported results — HPLC purity where the lab reports one, measured content on quantity-only certificates — before adding a peptide to your research workflow.
Confirm the compound name, variant, and available batch or lot reference align with the item you are evaluating.
Where the lab reports purity, HPLC separates the target compound from related impurities so the percentage is tied to analytical data, not marketing copy; on a quantity-only certificate, review the measured content per vial instead.
Where available, mass/identity details and technical specifications help researchers confirm the material matches the intended research compound.
COAs support lab documentation. They are not medical advice, dosage guidance, or a promise of human outcomes.
Each published third-party COA reports HPLC purity where the lab measures it, with identity results on Accumark reports.
Lot-level Certificates of Analysis are published on our COA page as each lab report comes in, each linked to the issuing laboratory's own record.
Supplied for in-vitro laboratory research applications. Not for human or veterinary use.
Peptides organized by receptor system and primary research application.
Peptides are fundamental tools in modern biochemical research, enabling precise investigation of biological processes.
Peptides are short chains of amino acids linked by peptide bonds. The sequence and length determine structural and functional characteristics.
Essential tools for receptor binding studies, enzyme kinetics, cell culture experiments, and protein interaction assays.
Solid-phase synthesis with HPLC purification ensures precise sequence assembly and removal of impurities.
I have been in business for over 20 years and have always looked for better systems. That started with process optimization in my earlier ventures. Then, about 8 years ago, that same research-driven mindset led me into peptide science. One minute you are optimizing a workflow, the next you are reading peptide research at midnight like a mad scientist.
That is where Peptide Hackers came from: peptide science, analytical testing, published research, documentation, and cutting through the noise with verified research materials.
