Its strongest area is operating history (9.1/10), with over eleven years of records; its weakest is transparency (4.5/10).
On lab evidence, the heaviest-weighted factor, Limitless Biotech has independently verified third-party COAs, with COA work on record from MZ Biolabs, TrustPointe Analytics, Vanguard Laboratory. Its lowest price per milligram in our data is on Glutathione (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 credibility7.5/10
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.

7.559 − 0.100 = 7.459, rounded to 0.1: 7.5/10.
Testing gate: 13 of 19 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.

Earlier audits (7)
- Audit · 6.41to6.85
Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.7 to 7.5.
- Audit · 6.31to6.41
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 6.5 to 7.0.
- Audit · 7.34to6.31
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 9.0 to 6.5, pricing 7.2 to 4.3, operating history 6.5 to 9.1, transparency 9.0 to 4.5.
- Audit · 7.29to7.34
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for site statements about testing that the certificates do not bear out. Lab 6.6 to 6.7.
- Audit · 7.46to7.29
Tenure 10 to 6.5. The company states it has operated since 2020, about six years, which falls below the top band reserved for businesses over ten years. Lab and the other subscores are unchanged.
- Audit · 8.55to7.46
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 15 of the 19 products we list that the vendor offers for sale. Lab 8.6 to 6.6.
- Audit · Verified, no change
Re-audited from live COAs, verified firsthand. Confirmed a strong dual-lab program -- TrustPointe (including rare USP<71> sterility testing) plus Janoshik, all independently verifiable at 99%+ purity. Rating held; fill variation observed but not scored against the vendor per policy.
Editor’s notes
Limitless Biotech publishes certificates from several laboratories. At our July 2026 audit, TrustPointe Analytics reports covered HPLC purity and content, endotoxin (USP <85>) and sterility (USP <71>), and Janoshik Analytical reports covered purity and identity, on some products with endotoxin, microbial limits or sterility. When we re-checked on 20 October 2026, most purity reports on the newest batches came from MZ Biolabs and carried a QR code leading to the laboratory's own certificate page; we confirmed nine there, including BPC-157, AOD-9604, KPV and LL-37 at 99.19% to 99.75%. Sterility and endotoxin reports on those batches came mainly from TrustPointe. Panels vary by product: the N-Acetyl Selank lot we score, lot 1376 from August 2026, has a TrustPointe sterility report but no endotoxin result on file. Certificates cover 15 of the 19 products we list. Semax and Selank are sold only as N-acetyl amidate forms. Since 23 September 2026, prices are shown only to logged-in accounts; we last read them on 22 October 2026. The company states that it has operated since 2020, but the store's domain was registered on 9 June 2015, and a customer described buying from the same store in January 2016; the operating-history score is counted from the June 2015 domain registration.
