How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility7.8/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Mean of 14 products: 111.5 ÷ 14 = 7.964.
- −0.20CLAIM Claims the certificates do not support (cap −0.3): 'Accredited Testing: Kovera Labs & Janoshik' (both accredited:false); every batch heavy-metal screened / endotoxin 'guarantees sterile' (most lack metals, none sterility)
7.964 − 0.200 = 7.764, rounded to 0.1: 7.8/10.
Testing gate: 13 of 14 products have a certificate from a directory laboratory (not tier D, not self-issued) with the key confirmed at the laboratory. That is at least half, so the vendor counts as third-party tested and no cap applies.

Lab rises from 7.23 to 7.8: 75 of 76 Kovera reports were verified in the laboratory's records, covering nearly every product, many with endotoxin and heavy-metal screens; there is no sterility testing and the AOD-9604 entry could not be verified. Shipping falls from 7.2 to 5.5 because all sales are final, the damage window is 48 hours, and lost or misdelivered parcels are covered only with paid insurance. Pricing moves from 9.5 to 8.6 on live selling prices about 22% below the market, with a small deduction because every product is shown against a struck-through regular price. Tenure 2.0 to 2.3 and transparency 7.2 to 6.5: the operating company and address are named, but the catalog and certificates are no longer public.
Editor’s notes
Onyx BioLabs publishes one of the deeper certificate libraries we have checked. Its lab results page links 76 Kovera Labs reports dated March to August 2026, and 75 of them match Kovera's own published records, covering nearly every peptide it sells. Every verified report shows purity above 99%, and the newer rounds add endotoxin and heavy-metal screens. Kovera is not an accredited laboratory, no report includes sterility testing, sermorelin has no certificate, and on 22 October 2026 the AOD-9604 report number matched Kovera's own published record for the same batch and purity. The catalog, prices and certificates are visible only after creating an account. In October 2026 prices ran about 16% below the market median on the products we compared, though every product is shown against a higher struck-through price, and GLP-1 compounds are sold under code names. All sales are final: damaged, wrong or missing items must be reported within 48 hours, and a lost parcel, or one marked delivered but not received, is replaced only if shipping insurance was bought at checkout. Cards are accepted alongside ACH, Zelle, Cash App and crypto. The policies name Onyx Holding, LLC, with a mailbox address at a UPS Store in Charlotte, North Carolina. The domain dates from August 2025, and the earliest archived copy of the store with prices is from March 2026.
