Transparency report · data through Sep 2026
A year of purity data, added up
Every supplier claims third-party testing. We publish ours — every batch, every certificate, including the ones we rejected. This is the aggregate analysis of 100 public certificates, so the claim can be checked against data instead of taken on faith.
77 batches · 2 independent labs
The distribution
All 77 research-peptide batches with a numeric HPLC result, including the low end:
Mean 99.56% · median 99.6% · range 97.77–99.98%. A further 21 certificates are identity- or endotoxin-only panels (blends, capsules, sprays); cosmetic-grade material is reported separately below.

Below 99%? It doesn’t ship.
Our acceptance standard is stricter than the lab’s reference spec: any batch testing under 99% purity is rejected and replaced by the manufacturer before sale. A transparency report that hides its worst numbers isn’t one — so the rejected batches’ certificates stay public:
- KPV — 97.77% (Oct 2025) · rejected and replaced
- GHRP-2 — 98.78% (Jun 2026) · rejected and replaced
- IGF-1 LR3 (0.1mg) — 98.83% (Jun 2026) · rejected and replaced
- Cosmetic-grade GHK-Cu (1g bulk) — 86.66%· cosmetic-grade material with no purity specification, listed separately from research-grade lots
Three rejections out of 77purity-tested batches is what the gate looks like working. Most suppliers wouldn’t test twice; almost none would show you the batch that failed.
What gets tested
- Purity — RP-HPLC (C18, DAD @ 214 nm), per vial and batch average
- Identity — LC-MS confirmation against reference standard
- Endotoxin — kinetic LAL assay per USP <85>, acceptance ≤ 0.5 EU/mL
- Heavy metals — arsenic, cadmium, lead and mercury screening

Every statistic above is computed from certificates you can download yourself — searchable by product and batch, with lab report numbers that can be confirmed with the issuing laboratory.
Methodology
Aggregated from the 100 unique certificates published in the Real Peptides public COA database for tests dated 2025-09 through 2026-08, across 57 products from Kovera Labs and Freedom Diagnostics. Purity figures are the certificate’s batch average where reported, otherwise the mean of per-vial results. Certificates providing only identity or endotoxin panels are counted in testing coverage but not purity statistics. Duplicate uploads of the same lab report are counted once. This page is regenerated as new certificates publish.
All products are supplied for laboratory research use only — nothing here is for human or veterinary consumption. Purity statistics describe tested material; they are not claims about suitability for any use.
