Is Oasis Labs legit?
Oasis Labs scores 7.30 out of 10 (Strong, #25 of 100) as of November 5, 2026 and passes our testing gate: all 18 products we score carry a certificate, 18 confirmed with the issuing lab (a lab we grade A-). Its strongest area is lab testing (8.3/10) and its weakest is transparency (0.5/10); its operating history on record covers over two years.
On lab evidence, the heaviest-weighted factor, Oasis Labs has independently verified third-party COAs, with COA work on record from Bioviridian. 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 credibility8.3/10
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 18 products: 152.5 ÷ 18 = 8.472.
- −0.20LOT Lot numbers that do not identify a single batch (cap −0.2): lot 253110 on 5 compounds and 262702 on 5 compounds (vendor bulk-submission labels)
8.472 − 0.200 = 8.272, rounded to 0.1: 8.3/10.
Testing gate: 18 of 18 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.

Audit history and why the rating changed
We re-audit vendors against their live COAs and site. Here is what most recently moved this rating, and why.

- Most recent audit · 7.29to7.30
Pricing re-checked on 5 November 2026 after the market medians were recalculated with Peptyes added pricing 7.5 to 7.6.

Market medians updated after S1Research was added pricing 7.6 to 7.5.

- Audit · 7.03to7.30
Certificate library re-checked on 23 October 2026: eleven new certificates confirmed at the issuing laboratories. Lab 7.8 to 8.3.
- Audit · 7.14to7.03
Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). BioChex's only report, for Oasis Labs retatrutide, was issued a few hours before the biochex.org domain printed on it was registered, and no other client was found, so its independence is not established (check L2): the certificate now scores the flat 2.0 (rule A3) and no longer counts toward the testing gate, which Oasis Labs still meets with 17 of 18 products. Separately, the printed October 2025 date on the Bioviridian sermorelin certificate (COA3255) was found to be a misprint contradicted by the laboratory's own records, so its March 2026 run date is used and it no longer counts as older than 12 months. Lab 8.0 to 7.8.
- Audit · 7.24to7.14
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: transparency 2.5 to 0.5.
- Audit · 6.96to7.24
Re-scored on 22 October 2026 under version 2 of our published rules. The seven Bioviridian certificates were confirmed at the laboratory, which raises each of them by the 1.5 points for a confirmed key. Lab 7.5 to 8.0. Score 6.96 to 7.24 (Fair to Strong).
- Audit · 7.23to6.96
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 8.0 to 7.0, pricing 7.0 to 7.6, operating history 3.2 to 3.4, transparency 6.0 to 2.5.
- Audit · 6.69to7.23
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: earlier judgement deductions that are not part of the published rubric were removed; fixed deductions apply for certificates more than 12 months old and one lot number printed on certificates for different compounds. Lab 6.5 to 7.5.
- Audit · 6.78to6.69
Tenure 5 to 3.2. The domain was registered in November 2024, about 23 months ago, and nothing on record supports an earlier start, so the operating-history score was aligned to that age. The public notes were rewritten to include the July 2026 findings.
- Audit · 8.55to6.78
Re-audited and COAs verified firsthand. The testing is genuine per-product (Bioviridian, mass-spec-confirmed identity + HPLC purity), correcting an earlier assessment that had doubted it. But the panels cover identity, purity, and content only, with no sterility, heavy-metals, or endotoxin testing, plus QC issues (a mismatched vial photo, a sample-mockup file still live). The previous 9.5 lab rating was inflated, so the score was lowered to a verified level.
Editor’s notes
Oasis Labs describes itself as Texas-based and veteran-owned, with fulfilment from Las Vegas. Its earlier certificates named Bioviridian, BioRegen and BioChex; on 23 October 2026 we confirmed newer Bioviridian certificates, issued June to September 2026 and naming Oasis Labs, for 11 products, so every product we list now carries a Bioviridian certificate. In July 2026 we checked two Bioviridian certificates by hand, and they could be looked up on Bioviridian's own verification page; the BPC-157 and FOXO4-DRI reports showed mass-spectrometry identity, HPLC purity and measured content. None of the certificates we have listed covers endotoxin, sterility or heavy metals. Several certificates share one lot number, which the vendor uses as a submission label, and at our July 2026 check several reports were dated 2025. In July 2026 we saw a vial photo of a different product on the FOXO4-DRI certificate, and a file marked as a sample mockup on the Snap-8 page. The certificates were first supplied to us by the vendor directly in May 2026 and re-checked against the site in July 2026. The vendor states that weekday orders before 2 PM Pacific ship the same day. The earliest dated customer review we found is from August 2024, which is what the operating-history score reflects.
