Onyx Bio Labs scores 81/100 in pepmg's criteria-based Vendor Score, which rates only what a vendor publishes about lab testing and about itself, not its products and not its prices. What we observed: a few COAs openable at the testing lab (6 of 134). The biggest credibility signal pepmg weighs is how a vendor publishes lab tests: the documents counted above open at the testing lab's own site (Freedom Diagnostics), where the lab itself can confirm the result, and the rest are hosted by the vendor, where it cannot. Neither price nor catalog size affects this score, but for context it prices around the tracked median across the compounds it shares with other tracked vendors, over 20 tracked listings. Its prices are machine-readable and it publishes an About page, and the domain has been online about 1 year. This rates what Onyx Bio Labs publishes about lab testing and about itself, not the purity or authenticity of any vial, which pepmg can't verify, so read the COAs yourself. Research use only.

What would raise this score. Published behaviour only. How a vendor runs its business is its own call, and none of this affects the $/mg ranking.
- 128 of the 134 published COA documents open on the vendor's own site rather than at the testing lab. Linking the lab's own copy on those pages would let a buyer confirm the result at the source. (up to +19)
Computed from what this vendor publishes about lab testing and itself. Price and catalog size are shown above as facts and are deliberately NOT scored — $/mg is the ranking, and it is affiliate-blind. No opinions, no testimonials.

Certificates you can check at the lab
6 of 134 COA documents Onyx Bio Labs publishes resolve to a report hosted by Freedom Diagnostics, between them 3 distinct lab reports — several documents can point at the same report, and each report is listed once below. The lab's copy is linked first because it is the one the vendor cannot edit. pepmg has not tested anything — the lab's own copy is linked; we did not read the certificate or vouch for it, and some labs bot-block our crawler, so a link may be one a person can open and we could not. A certificate covers the batch it was issued for, which may not be the vial you receive.

We don't host reviews — an unverifiable review box is a magnet for bots and paid posts, and we won't pretend otherwise. Instead, here's where you can read what real buyers say about Onyx Bio Labs, on sites we don't control:
These are independent, unmoderated sources — we link them, we don't vouch for them, and a "profile" or "search" link may turn up little or nothing. pepmg's job is the part we can stand behind: prices captured first-party with a timestamp, ranked purely by $/mg, plus the objective Vendor Score above. Vetting a source you're about to buy from still matters, and that call is ultimately yours — we've made it as informed as we honestly can.
Vendor links are temporarily offline while we review our referral and linking policies. Listings remain for price transparency.
