Kovera certificates with access codes and net content, a company with an address, a modest but real review base, and low prices. The badge that rounds 4.5 up to 4.6 is small but it is the vendor's own claim disagreeing with the record, and that is the point it loses.

Rubric breakdown
| Criterion | Evidence |
|---|
| ✔ | Names its testing laboratory
The lab is identified by name on the vendor's site; you can look it up and contact it. | Kovera Labs named on all batch certificates; Janoshik for HCG (6 Sep 2026) |
| ✔ | Certificates verifiable at the lab, not just the vendor
COAs are hosted on the testing lab's own system or carry a lab-side lookup code. | Certificates carry Kovera-format access codes (e.g. EHNOQRS) for koveralabs.com/verify |
| ✔ | Batch-specific COAs matched to lots
Certificates carry lot numbers that match shipped vials, not one generic PDF. | Per-batch certificates listed on /lab-results/ (e.g. TIR30-260901A) |
| ✔ | Publishes measured net content vs label
COAs state measured milligrams against the labelled amount, not purity % alone. | Certificates state net content (e.g. tirzepatide 30mg batch TIR30-260901A: 99.233% purity with net-content line) |
| ✔ | COAs and pricing viewable without an account
Open the COA library and catalog logged out. | Catalog, pricing and certificates viewable without an account |
| ✔ | Independent review base (50+ on an external platform)
Check the vendor on Trustpilot or an equivalent platform the vendor cannot edit. | 4.5 / 65 on Trustpilot (verified 14 Aug 2026) |
| ✘ | No contradictions among its own claims
Compare testing/lab statements across the vendor's own pages. | Not awarded |
| ✔ | Vial sizes stated with prices
Catalog or product pages show milligrams next to every price. | Sizes stated with prices (BPC-157 5mg $29.99 / 10mg $39.99, NAD+ 500 $58.99) |
| ✔ | Publishes a legal entity and street address
The company's registered name (LLC, Inc., s.r.o. …) and a street address appear on the vendor's own Contact, About or Terms pages — not only a brand name, a city, or hidden page markup. | Onyx Holding, LLC · 9311 JW Clay Blvd STE 2050A, Charlotte, NC 28262 — on-site (6 Sep 2026) |
| ✔ | No misleading trust signals or buyer-protection workarounds
Compare any on-site review score or badge with the independent platform; check whether the vendor only takes, or pushes you toward, payment rails you cannot dispute; check FDA and BBB records. Awarded unless one of these is on record. | No on-site review badge contradicting the independent record; card payment accepted; no regulator action found (checked 6 Sep 2026) |
Frequently asked
Is Onyx Biolabs legit?
Kovera certificates with access codes and net content, a company with an address, a modest but real review base, and low prices. The badge that rounds 4.5 up to 4.6 is small but it is the vendor's own claim disagreeing with the record, and that is the point it loses. As of 6 September 2026, Onyx Biolabs scores 9/10 on our verification rubric and has an independently viewable rating of 4.5 (65 reviews).
Does Onyx Biolabs publish third-party COAs?
US-based in Charlotte, North Carolina. States third-party HPLC and mass spectrometry testing and maintains a public database of 50+ independent lab reports. Free ground shipping over $200.
What should buyers watch for with Onyx Biolabs?
The 65-review base is still modest. Independent reviewers have questioned the >99% purity claim because the certificates are not independently verified. Multiple similarly named Onyx storefronts exist with overlapping catalogs — confirm which one you are ordering from.
How much is BPC-157 at Onyx Biolabs?
10mg was $39.99 on 6 September 2026 (5mg $29.99). Prices move; we record what we saw and when.
