OMNI Peptides scores 6.08 out of 10 (Fair, #59 of 100) as of November 6, 2026 and passes our testing gate: 12 of the 17 products we score carry a certificate, 12 confirmed with the issuing lab (labs we grade B+). Its strongest area is shipping and refunds (7.0/10) and its weakest is transparency (3.0/10); its operating history on record covers over two years.
On lab evidence, the heaviest-weighted factor, OMNI Peptides has independently verified third-party COAs, with COA work on record from Accumark Labs, ILS Laboratories. We hold 14 lot certificates in all. Its lowest price per milligram in our data is on NAD+ (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 credibility6.5/10
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.

No certificate on file for this product: scores 0, counted at 0.5 weight because it is not one of the core products.
Weighted mean of 17 products (3 non-core products without a certificate counted at half weight): 100.0 ÷ 15.5 = 6.452.
No adjustments.
6.452 = 6.452, rounded to 0.1: 6.5/10.
Testing gate: 12 of 17 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.

Pricing5.1/10
We compared OMNI Peptides’s current single-vial prices on 16 products, each matched to the same product and milligrams per vial, with the median price of the other vendors. Its typical price (the median ratio across those products) is 27% above the market median (ratio 1.27), which the published scale maps to 5.1/10. checked
Operating history3.7/10
Counted from March 12, 2024, the earliest dated evidence of this business operating: 2.6 years as of October 22, 2026, which the published table maps to 3.7/10.
Domain omnipeptides.com registered 2024-03-12 (RDAP, 12-year term) and never shown parked or for sale. Wayback 2025-03-08 shows the Omni Peptides WooCommerce store selling with prices (BPC157 5mg [price], tirzepatide, semaglutide, etc.), well before the July 2026 'launch' press release that the stored 1.5 relied on. No capture exists between registration and 2025-01-07 (a 202 challenge page), so selling is verified from 2025-03-08 (19.5 months, score 2.8) and the domain date is used under the published rule.

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.
See the full score history and chart
- Most recent audit · 6.19to6.08
Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 6.7 to 6.5.
- Audit · 6.17to6.19
Scores re-checked on 6 November 2026 after the correction review pricing 5.0 to 5.1.
- Audit · 6.06to6.17
Core products recomputed on 29 October 2026 (rule A1b): listings added for newly reviewed vendors made NAD+ a core product in place of CJC-1295, so a missing certificate for each now counts at its new weight: lab 6.5 to 6.7.

Pricing recomputed on 25 October 2026: listings added for a newly reviewed vendor (Pexo Labs) moved the market median for the same products: pricing 5.2 to 5.1.
- Audit · 6.12to6.09
Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 5.4 to 5.2.
- Audit · 6.09to6.12
Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 5.2 to 5.4.
- Audit · 6.11to6.09
Pricing recomputed on 23 October 2026 under the revised rule E1 (standing offers), which prices a size at the lowest total a buyer can pay without a code under standing prices, so a standing offer that includes a second vial at no extra cost now counts at all the milligrams received, in the vendor's own price and in the market medians for the same products: pricing 5.3 to 5.2.
- Audit · 6.12to6.11
Pricing recomputed on 23 October 2026 from current listings with the published rule (section E), after listings added or updated since 22 October, including a newly reviewed vendor's, moved the market median for the same products: pricing 5.4 to 5.3.
- Audit · 5.79to6.12
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 5.9 to 6.5.
- Audit · 5.72to5.79
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 6.0 to 7.0, transparency 5.5 to 3.0.

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. pricing 6.5 to 5.4, operating history 1.5 to 3.7.
- Audit · 6.38to5.77
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 12 of the 17 products we list that the vendor offers for sale. Lab 7.0 to 5.9.

Editor’s notes
OMNI Peptides publishes a certificate library from two independent laboratories, Accumark Labs and ILS Laboratories, and every one of its 14 certificates checks out with the laboratory that issued it. The ten Accumark certificates match the laboratory's own copies exactly and name OMNI Peptides as the client. The four ILS certificates match the laboratory's portal records, which name OMNI Peptides as the client, although three of the ILS documents posted by the vendor print a different company name, Peptide Science USA, in their Tested for field. They cover identity, purity and measured content, and none include an endotoxin or sterility screen. In October 2026 prices ran about a quarter above the market overall, and every product is shown as discounted from a higher regular price. Orders placed before noon Eastern ship the same business day within the US, but all sales are final: damaged, wrong or missing items reported within 48 hours are replaced or credited, and lost parcels are traced with the carrier rather than reshipped. The site names no operating company and lists a Las Vegas mailbox address. Its domain was registered in March 2024, and an archived copy shows the store selling with prices in March 2025. Certificates from Accumark Labs and ILS Laboratories, each confirmed on the lab's own lookup, cover 12 of the 17 products offered; CJC-1295 without DAC, cagrilintide, retatrutide, KLOW and GLOW had no certificate when we checked in October 2026.
