Onyx Biolabs has competitive prices and a named company, but thin testing documentation. As of October 19, 2026 it names Onyx Holding, LLC in Charlotte, NC and a testing lab, Kovera. Most of its compounds were priced below the median in our index. We couldn't find a COA page, and we found no independent Finnrick tests.
Notice: Onyx Biolabs' products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices only. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

Prices as listed on October 19, 2026; every listing showed a sale price with a crossed-out "was" price. We didn't see retatrutide, tirzepatide or semaglutide in the prices we could read. Compare BPC-157 prices, GHK-Cu prices and MOTS-c prices in our price index.
Testing and COAs
The site names Kovera as a testing lab, and its footer links to a "lab results" section. We didn't find a public COA page we could read, lot or batch numbers tied to certificates, or any mention of endotoxin or sterility testing. The login gate may hide some of this. We haven't verified anything with Kovera.
We found no Finnrick tests for Onyx Biolabs, so there's no independent, customer-submitted data to check against.
What we like
- Names its company (Onyx Holding, LLC) and city (Charlotte, NC).
- Names a testing lab, Kovera.
- Most compounds priced below the index median, some by 40% or more.
- Several payment options, including ACH and cards.
What to watch
- No public COA page or lot-matched certificates found.
- No endotoxin or sterility testing mentioned.
- No independent Finnrick tests found.
- A login gate in front of the shop.
- Every price is shown as a discount from a higher "was" price, so treat the "was" figures with caution.
How it compares
Onyx Biolabs competes on price more than on documentation. Compare it against all vendors we track, check peptide deals this week or see our ranked list.
Bottom line
Onyx Biolabs is a named Charlotte company with prices below the index median on most compounds we checked. Its testing documentation is the weak point: no public COAs and no Finnrick data. Ask for a lot-matched COA before ordering.
