Quality & Handling
Every retail product is independently tested by a third-party lab for identity, quantity and purity before it ships. This page explains exactly what we test, how to store your research compounds, and how to reconstitute them correctly.
How we verify our products
No product enters our catalogue without completing independent third-party testing. Every lot is tested for identity, quantity and purity by Accumark Labs, and we publish the actual certificate on our Lab Results page rather than simply declaring a “pass.” Most certificates link directly to the lab’s own verification portal, so you can confirm the result at the source.
| Test | Method | Specification |
|---|---|---|
| Identity | HPLC | Matches declared compound |
| Quantity | Measured | Reported in mg |
| Purity | HPLC-UV 220nm | >98.0% (we list ≥99%) |
Additional analyses such as mass spectrometry or endotoxin screening are not part of our standard panel. Where a lot has had further testing, the certificate will show it. Actual results for every tested lot are published on our Lab Results page.
How to read a COA
A Certificate of Analysis is the primary accountability document in research-compound supply. Where a product has completed testing, its COA is published on our Lab Results page. Here’s what each section tells you.
Maintaining compound integrity
Improper storage is the most common cause of peptide degradation outside the laboratory. These guidelines apply to all Pacific Peptides lyophilized products unless the specific product page states otherwise.
Step-by-step reconstitution
Provided for qualified researchers conducting in-vitro research only. This is not medical advice.
From our lab to yours
Compound integrity doesn’t stop at the lab door. Our shipping protocol maintains stability, protects vials from damage, and ensures complete discretion.
