Compare peptide purity across brands using real third-party lab tests from Peptigrity — with the test spread (not just an average) and net peptide content (how many mg are actually in the vial), both computed from the lab database. Built on independent tests: no test can be paid for, hidden, or removed.

Purity is the percentage of the sample that's the target peptide. Net content is how many milligrams of actual peptide are in the vial after water, salts, and solvents. A vial can be 99% pure but contain far less peptide than its label says — net content is the number that determines your real dose. A 99%-pure vial at 60% of label is worse than a 97%-pure vial at 105%.
Learn more in how peptide testing works.
Peptide purity is one of the most important quality indicators. Higher purity means fewer impurities, degradation products, and potential contaminants. Third-party lab testing by independent laboratories provides the most reliable purity data — more trustworthy than vendor-provided certificates.
But purity alone doesn't tell the whole story. Always check the test count. Eight tests all landing at 99%+ is far stronger evidence than a single test at 99.9% — which is why this tool shows the spread and flags single-test brands.
HPLC separates a peptide sample into its individual components and measures the proportion that is the target peptide versus impurities. 99% purity means 99% of the sample is the target peptide.
| Purity Range | Classification | Typical Use Case |
|---|---|---|
| ≥ 99% | Excellent | Quantitative research, sensitive assays |
| 98–98.9% | Research grade | General research applications |
| 95–97.9% | Marginal | Screening, preliminary research only |
| < 95% | Below standard | Not suitable for most applications |
Results come from independently commissioned tests (samples purchased anonymously and tested blind), verified community-submitted reports, and vendor-submitted third-party results — all linked to the original lab documentation. No test can be paid for, hidden, or removed, the same independence promise as the Trust Score. For guidance on commissioning your own test, see how to get your peptides independently tested.
