Is Cernum Biosciences legit?
Cernum Biosciences scores 4.68 out of 10 (Weak, #73 of 100) as of November 6, 2026 and passes our testing gate: all 14 products we score carry a certificate, 13 confirmed with the issuing lab (a lab we grade B+); 1 of those certificates is vendor-issued or from a source whose independence we could not establish. Its strongest area is shipping and refunds (5.5/10) and its weakest is transparency (1.0/10); its operating history on record covers about eleven months. We also record that most of its certificates were issued to another business.
On lab evidence, the heaviest-weighted factor, Cernum Biosciences has independently verified third-party COAs, with COA work on record from Janoshik Analytical. Its lowest price per milligram in our data is on GHK-Cu (see the table below).
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 credibility4.9/10
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.

Earlier audits (12)
- Audit · 4.97to4.69
Lab evidence re-checked on 4 November 2026. The Janoshik reports tested on 3 November 2025 (GHK-Cu, MT-2, retatrutide and IGF-1 LR3) passed 12 months old and are the newest on record for those products, so under the published age rule (A6) each now carries the age deduction, alongside the older reports already past 12 months. Lab evidence 5.4 to 4.9.
- Audit · 5.24to4.97
Lab score corrected on 1 November 2026: the stored sub-score read 5.9 while the uniform rule gives 5.4, because the three Janoshik reports tested on 31 October 2025 (BPC-157, CJC-1295, tesamorelin) passed 12 months on 31 October 2026 and each now carries the age deduction (rule A6), alongside the six reports from May 2025 already past 12 months; stored value corrected to the rule. Lab 5.9 to 5.4.
- Audit · 5.29to5.24
Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 5.3 to 5.0.
- Audit · 5.26to5.29
Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 5.1 to 5.3.
- Audit · 5.25to5.26
Operating history re-checked on 22 October 2026 under the published rule (earliest dated evidence of the business, including a never-parked store domain and the named operating company, looked up for every vendor): operating history 1.7 to 1.9.
- Audit · 5.07to5.25
Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 4.5 to 5.5, transparency 1.5 to 1.0.
- Audit · 5.25to5.07
Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 3.3 to 4.5, pricing 7.6 to 5.1, operating history 2.0 to 1.7, transparency 2.0 to 1.5.
- Audit · Verified, no change
Independent testing confirmed: the vendor's Janoshik certificates were opened at the laboratory's own verification site on 22 October 2026, so the untested cap no longer applies.
- Audit · 4.58to5.25
Janoshik certificates confirmed on 22 October 2026 at the laboratory's own verification site, so each confirmed report now earns the key-confirmed credit under our published lab rule. Lab 4.7 to 5.9.
- Audit · 4.31to4.58
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the Janoshik reports linked for 13 of the 14 products we list are now scored as laboratory reports rather than vendor sheets, including the GHK-Cu and PT-141 reports, while Semax shows only a vendor-issued sheet; fixed deductions apply for certificates more than 12 months old, certificates ordered by a supplier or issued to another business, site statements about testing that the certificates do not bear out and one lot number printed on certificates for different compounds. Lab 4.2 to 4.7.
- Audit · 3.65to4.31
Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 13 of the 14 products we list that the vendor offers for sale. Lab 3.0 to 4.2.
- Audit · 2.05to3.65
Re-audited on 2026-10-18. The second set of images on each product page, labeled as third-party tests and not assessed in May, was read in full: they are Janoshik Analytical reports ordered by the Chinese manufacturer on its own material, with no batch identified, rather than tests of Cernum's stock. Lab moves from 0 to 3.0 to credit that supplier testing, while testing of Cernum's own lots remains unestablished, so the third-party gate still applies. Pricing eases from 7.9 to 7.6 on a fresh comparison of 20 products about a fifth above the market median. Shipping, tenure and transparency are unchanged: no returns, discretionary refunds, and no company or address published.
Editor’s notes
Cernum Biosciences sells about two dozen research peptides and blends; its domain was registered in November 2025, and the earliest archived copy of its store dates from January 2026. Each product page links two documents. The one labeled a certificate of analysis is issued by Cernum itself, with no laboratory named. The one labeled a third-party test is a Janoshik Analytical report, but every one we read was ordered by the Chinese manufacturer, Shanxi Qianyecao Biotechnology, on a sample of its own material with the batch recorded as unknown, between May and November 2025. These reports describe the supplier's production rather than a Cernum lot, and the product pages do not say so. On 22 October 2026 we confirmed the 13 reports linked from the products we list at Janoshik's own verification site. Several products, including semax and kisspeptin, have no third-party report at all. The site describes its products as independently tested by accredited laboratories, which these documents do not show. At our 22 October 2026 check, standard prices ran about a quarter above the market median on most products we compared. Returns are not accepted, refunds are at the company's sole discretion, and damage must be reported within 24 hours. No operating company or address is published. As of October 2026, 13 of the 14 products we list link a Janoshik test report, each ordered by the Chinese manufacturer on its own material with no batch recorded, six dating from May 2025; all 13 were confirmed at the laboratory on 22 October 2026, and semax has none. On 1 November 2026 the three reports tested on 31 October 2025 also passed twelve months, so nine of the thirteen now carry the age deduction.
