Pick a panel depth and scroll — the chromatogram draws, peaks integrate, and identity is confirmed by mass, in up to twenty replicate determinations per lot.

Illustrative display
Remote screening
Photograph a vial. Get a read in seconds.
Upload a photo and an automated visual check reads color, clarity, cake condition and the label’s claims — before anything ships. A screening aid, not a certificate of analysis.
Process
From sample receipt to verified report.
- 01
Request
Specify the compounds, lot count and panel depth. No supporting documentation is required.
- 02
Ship
The quotation specifies the vial count required per lot and the shipping address.
- 03
Intake
Each vial is logged against its lot and assigned a sample identifier before any container is opened.
- 04
Analysis
The panel is executed assay by assay. Each result is reviewed before inclusion in the report.
- 05
Report
One batch-specific certificate is issued per lot, with a report ID verifiable on this site.
The Industry Standard
The standard the industry tests against.
“Lab tested” means nothing without a method behind it. Our panels define what a peptide certificate has to show — every claim measured by a referenced method, reviewed, and verifiable by anyone holding the report ID.
Reference methods only
Assays follow USP general chapters — <85>, <71>, <467>, <788> — under ISO/IEC 17025 principles. No in-house shortcuts.
Batch-specific by definition
One certificate per lot, drawn from vials of that lot. A COA that doesn’t name the batch it came from doesn’t meet the standard.
Verifiable by anyone
Every report ID resolves on this site and is anchored on-chain at issue. A result that can’t be independently checked doesn’t count.
Adopted as the benchmark
Vendors publish our panels as their release criteria and buyers ask for them by name — across 10k+ lots tested to date.
Backed on the blockchain
Every certificate, anchored on-chain.
When a COA is issued, a matching token is minted on a public blockchain — an immutable, timestamped fingerprint of the report. A certificate altered after the fact no longer matches its token, so anyone can confirm the report they’re holding is the one we issued.
Questions
Frequently asked questions.
What is 8X testing?
8X is industry shorthand for eight test categories run on the same lot: identity, purity, net peptide content, bacterial endotoxins, heavy metals, sterility, vial-to-vial conformity and a fentanyl screen. It is not an FDA or USP classification, so the methods behind the label matter. Ours are listed assay by assay above.
What do the higher panels add?
10X adds residual solvents and water content. 12X adds counter-ion content and MS/MS sequence confirmation. 15X tests the vial itself: container closure integrity, solubility and clarity, and pH. 20X adds appearance, visible and subvisible particulates, aggregates and chiral purity. The 15X and 20X additions are tests used in pharmaceutical quality control of injectable peptides.
Why isn't a purity result enough?
Purity is an area percentage from one chromatogram. It says nothing about how many milligrams are in the vial, whether the main peak is the right molecule, or whether the vial carries endotoxin, metals or microbes. Each of those needs its own assay.
Why test the same batch up to twenty times?
Because variance comes from two directions. The product itself varies — fill weight, moisture and degradation differ vial to vial even within one lot. And the testing varies — columns age, detectors drift, calibrations wander between runs. A single measurement carries both kinds of noise and you can't tell them apart. Repeating the tests and averaging turns that scatter into a mean with a known spread, exposes outlier vials, and gives you a number you can be confident in.
What does testing cost?
Per sample: purity, identity and quantity together are $215; bacterial endotoxins are $180; heavy metals are $105; sterility is $290 — $790 for the full panel of all four. Residual solvents and the deeper panel work are quoted per project, as scope depends on the material and lot count. Multi-lot submissions are quoted together.
How many vials do I send?
It depends on the panel. Conformity compares individual vials from the same lot, and sterility and endotoxin each need their own material, so deeper panels need more vials. We confirm the exact count with your quote.
Does a certificate mean a product is safe to use?
No. A certificate reports analytical results for the sample submitted. It is not regulatory approval, and it does not establish that any material is safe or effective for human or veterinary use.
