Open Assay tracks research peptide suppliers worldwide on an independent, evidence-first basis. If you operate a research-use peptide business and want to be on the leaderboard — or to enroll in the Golden Sample transparency program — read the criteria below and send us a note.
A verifiable shipping address of record — US, EU, UK, Swiss, Australian, or other jurisdictions are all in scope. What matters is that we can purchase anonymously through your normal retail channel and take delivery under a chain of custody we can document. International suppliers shipping into our lab jurisdictions are welcome.
Products sold explicitly for research use. Sites that market directly to human consumers, or that use therapeutic language in product pages, are out of scope regardless of test outcomes.
Publish third-party COAs that match a specific lot/batch, with a named analytical lab. Self-attested "in-house" testing does not meet the bar.
No active federal prosecution, no recent voluntary shutdown for regulatory cause, no documented data-falsification history of ownership.
A reachable contact (phone, email, or ticketed support) that responds within a week. We will attempt to contact you via the listed channel before publication.
The Golden Sample program is an optional second track — separate from the blind testing that drives your leaderboard rank. Vendors who opt in ship us a sample directly, we film the unboxing end-to-end, and we test it at the same lab under the same thresholds. The result is published as its own entry on your supplier page, alongside a standalone Golden vs Blind delta when we have both.
The value to a vendor with clean operations is real: a small or zero delta on a peptide where we've blind-purchased and golden-sampled both is the cleanest public signal you can buy. And you cannot buy it — you can only earn it by having consistent material. That's the whole point.
Your supplier-leaderboard position is determined entirely by blind-purchased samples we buy anonymously. Golden-sample participation cannot move your ranking up or down, and we publish this rule on every vendor page.
When you enroll, we request a specific peptide from your current catalog. You do not get to ship us your best SKU. If you refuse the requested peptide, you do not lose ranking — the golden-sample entry just does not happen.
We film and publish the unboxing end-to-end with no edits. Your packaging, placards, batch cards, printed COA, and anything else in the box gets catalogued publicly.
Golden samples are tested at the same analytical lab and under the same pass/fail thresholds as blind samples. No special treatment.
If we have both a blind-purchase and a golden-sample assay of the same peptide, we publish the purity delta (golden - blind) as a standalone field on your supplier page. A small delta is the signal you want.
There is no signup fee, no listing fee, no pay-to-play. Editorial independence is the product.

We aim to acknowledge applications within five business days. Review and first publication typically take three to eight weeks and include at least one blind purchase.
