No FDA agency checks the finished research peptides sold to end buyers, so third-party quality signals carry weight. Several aggregators have built structured data sets around vendor quality. They are not equivalent. They differ in who pays for the tests, what gets measured, how scores are scaled, and how their data sets relate to one another. Knowing those differences helps you read any composite score, including the peptideone Score, without treating overlapping signals as if they were independent.
Finnrick
Finnrick (finnrick.com) runs the largest primary-testing operation in this space. It buys peptide samples itself and commissions its own tests at commercial analytical laboratories, instead of curating vendor-published certificates of analysis. Per Finnrick's own site, as of mid-2026 it reports 8,026 individual tested samples covering 225 vendors across 15 popular peptides. Each tested sample gets a 0–10 score built from three parts: purity (0–4 points), quantity accuracy versus the label or batch claim (0–4 points), and batch-information quality (0–2 points). Those roll up into an A–E rating applied to each product/vendor pair, with X used when too few tests exist. Because Finnrick controls both sample acquisition and lab selection, its data set is the closest thing available to independent quality surveillance.
VialAudit
VialAudit (vialaudit.com) works as an anonymous blind-order audit desk. It places orders under an alias and ships the received product to two rotating, undisclosed third-party laboratories. The labs stay blind to the vendor until a report is filed, so vendors can't pre-screen by lab signature. VialAudit then publishes a 0–100 composite audit score for each vendor. The composite weights four dimensions: purity (40 %), label accuracy (25 %), shipping (20 %), and customer service (15 %). It runs quarterly audit cycles on the vendors it covers and also keeps a COA archive, a pricing index, and a public corrections log where prior scores can be challenged and revised with new evidence. The output is a vendor-level audit, not a per-peptide grade, and the lab rotation is built to limit gaming. Because VialAudit sources its own samples and picks its own labs independently of Finnrick, the two data sets don't overlap.
Peptigrity
Peptigrity (peptigrity.com) does something else. It aggregates individual, per-test HPLC records at the record level rather than rolling them into a proprietary grade. Each entry names the peptide, the vendor, the reported purity percentage, the test date, and, where available, the specific laboratory that ran the analysis. Commonly named labs in this ecosystem include Janoshik, Freedom Diagnostics, and Vanguard. Its stated positioning, "we don't sell peptides — we verify them," sums up the model. Because lab attribution shows up per record, you can see which facility produced a given result. That makes Peptigrity one of the more granular public HPLC record sets currently available.
PeptideBenchmark
PeptideBenchmark (peptidebenchmark.com) is a meta-aggregator, not an independent testing source. It normalizes Finnrick's test data (a 10-point average from Finnrick's vendor table) and Peptide Critic's community ratings (a 5-star scale normalized to 10) into a single 0–10 benchmark score, then orders vendors with a stricter board-rank model that rewards deeper evidence and reviewed transparency work. The normalization work adds real value. Source confidence pullback and vendor weighting are useful. But because PeptideBenchmark's underlying test data largely re-blends Finnrick, it is not independent of Finnrick. Treat both as separate inputs in a composite and you double-count the same lab results.
Comparison at a glance
| Finnrick | VialAudit | Peptigrity | PeptideBenchmark | |
|---|---|---|---|---|
| Who commissions tests | Finnrick (self-procures) | VialAudit (blind orders) | External labs (record aggregation) | Pulls from Finnrick + Peptide Critic |
| Test scale | 8,026 tested samples, 225 vendors | Vendor audit (~0–100) | Per-record HPLC entries | Hundreds of vendors ranked 0–10 |
| Output unit | A–E grade per product/vendor pair | Composite audit score | Raw purity % per test record | Benchmark score + board rank |
| Lab attribution | Not published per test | Two rotating, undisclosed labs | Explicit per record (where available) | N/A (inherited from inputs) |
| Independent of Finnrick | Yes (primary source) | Yes | Yes | No (re-blends Finnrick) |
How peptideone uses these signals
The peptideone Score (0–10) is a weighted composite of the three genuinely independent signals: Finnrick (weight 0.45), VialAudit (0.30), and Peptigrity HPLC purity (0.25). PeptideBenchmark is left out of the composite on purpose, to avoid double-counting Finnrick data. Where a vendor shows up in PeptideBenchmark, that context appears separately on vendor profiles as supplementary information, not as an input to the score.
No score on this site is a medical recommendation or a safety certification. These are research-quality data signals from a market that operates outside standard pharmaceutical regulatory frameworks. Products in this market are sold for research use only and are not approved for human consumption.
