▸ Vendor comparison
ABC vs Peptira LLC
A head-to-head, evidence-first comparison of ABC and Peptira LLC — built from 414 and 378 tracked third-party lab records respectively. Exact result/date/dose duplicates are collapsed in the quality comparison so one certificate arriving twice cannot count twice. TitrateLab does not rank or endorse vendors and takes no payment for placement.

How these metrics are calculated
Lab reports
Deduplicated published reports attributed to this vendor.
Compounds covered
Distinct normalized compound names represented in the counted reports.
Tested by Janoshik
Share of counted reports performed by Janoshik. Coverage, not quality.
Fill measured
Share of counted reports with a classifiable measurement against the printed fill amount. Finnrick batch-claim rows are excluded.
Endotoxin tested
Share of reports carrying a classifiable endotoxin outcome. Coverage, not a pass rate.
Average purity
Mean of positive purity tests. Identity failures are counted separately.
Purity below 90%
Share of positive purity results measured below 90%. Exact-zero identity failures are counted separately.
Compound not detected
Labelled compound not detected, as a share of reports that reported a purity outcome.
Underfilled >15%
Share of fill tests measured more than 15% below the printed amount. Vendor batch claims are never used.
Fill within ±10%
Share of classifiable fill tests measured within 10% above or below the printed amount.
Overfilled >10%
Share of classifiable fill tests measured more than 10% above the printed amount.
Endotoxin failures
Share of classifiable endotoxin outcomes assigned to the canonical failure tier.
Unknown / 0% results
Reports without a positive purity result or a classifiable printed-fill result; a report missing both is counted once, and exact 0% results are included.
Latest test
Most recent valid test date at or before today. Recency is context, not quality.
Observed third-party reports only. These figures describe tested batches, not every lot sold, and do not rank or endorse either vendor.

These figures are purity analytics aggregated from independent third-party certificates of analysis, not vendor claims. Purity is measured on the specific batches submitted for analysis and is not a guarantee for any other lot. This is research-use-only information; TitrateLab does not rank or endorse vendors and this is not a recommendation to purchase or use any product.
