From Sample to COA in Days
Select a panel, ship your sample, we run the analytics, you receive a full certificate of analysis. Most chemical panels return in 5–11 business days. Rapid sterility via Celsis in 5–7 days.
Independent. Third-party. Documented.
Supplier COAs Are Not Independent Verification
A certificate of analysis produced by the same organization that sold you the peptide is not third-party analytical data. It is a supplier document. Independent testing means a separate laboratory — with no financial relationship to the supplier — runs validated analytical methods on the actual sample you submit and returns instrument data, chromatograms, and a signed COA under their own accreditation.
Atumnus Labs operates as that independent laboratory. We have no affiliation with peptide suppliers or compounding operations. Every result we return is produced on your submitted sample using validated methods, with full instrument data in the COA. When 73% of independently tested peptide samples show purity discrepancies from supplier COAs, the value of a COA depends entirely on who produced it.
Our workflow is structured to make the process as direct as possible — select a panel, ship a sample, receive results. No ambiguity about what is included, what the turnaround is, or what the COA will contain.
Standard chemical panels return in 5–11 business days. Rapid sterility via Celsis in 5–7 days vs the 14-day USP 71 hold.
Every COA includes chromatograms, raw instrument output, methodology documentation, and analyst certification — not just a pass/fail summary.
All panels are published at fixed prices. No quotes required for standard tests. No surprise fees when results arrive.
The Testing Workflow
Four stages from submission to COA delivery. Each stage has a defined deliverable.
Choose Your Testing Panel
Select the analytical panel that matches your requirements. Basic purity by HPLC starts at $160. The full injectable safety panel — expanded purity, potency, heavy metals by ICP-MS, endotoxin, and rapid sterility via Celsis — is $1,050. Individual tests can be ordered standalone or combined. Pricing is published; nothing is added without your authorization.
If you are unsure which panel fits your situation — compounding pharmacy batch release, GLP-1 clinic supplier verification, research vendor COA documentation — contact us before submitting. We will match you to the right panel for your application and regulatory context.
Ship Your Sample
Most panels require 10–50mg of lyophilized peptide or liquid formulation depending on the tests ordered. We provide packaging guidance and accept overnight shipments from anywhere in the United States. A chain of custody form accompanies every submission — this documents the sample from your hands to our receiving team and is included in the final COA package.
If you are submitting multiple lots for supplier comparison or a batch series for release documentation, we coordinate chain of custody across all samples so the resulting COAs are structured for direct comparison. Contact us before shipping multi-lot submissions.
Testing Runs
All analytical work is performed using validated methods. HPLC purity by reverse-phase UV at 220nm. LC-MS identity confirmation by ESI mass spectrometry against reference standards. ICP-MS for elemental impurities against USP 232/233 limits. Endotoxin by LAL assay per USP 85. Sterility by USP 71 incubation or Celsis rapid method. Each method produces raw instrument data that is included in the COA — not just a derived result.
Sterility and endotoxin testing require method suitability to be established before results are analytically valid. If you have not previously established method suitability for your formulation, we offer sterility method suitability ($1,800), endotoxin method suitability ($675), and potency method suitability ($1,200) as standalone services that run prior to or concurrent with sample testing.
Receive Your Certificate of Analysis
Your COA includes the test methodology, instrument data, result values with pass/fail determination against stated specifications, analyst certification, and complete chain of custody from sample receipt through result sign-off. Expanded panels include full chromatograms. All COAs are delivered electronically and archived in the client portal for future reference or regulatory documentation.
White-label COA reporting is available for clinics and pharmacies that need results delivered under their own brand. Contact us to set up a white-label account before submitting your first sample.
What Makes a COA Defensible
A COA that can withstand regulatory scrutiny — from a state board inspection, a clinic's vendor qualification process, or an FDA review — is not just a results summary. It is a document that demonstrates the chain of evidence from sample receipt through analysis to result, with enough methodology detail that the analysis could be independently reproduced.
The most common deficiencies in peptide testing COAs are: missing method documentation, results without instrument data, chain of custody gaps between sample receipt and analysis, analyst certification absent or unsigned, and pass/fail determinations against unstated specifications. Any of these gaps makes the COA difficult to defend under review even if the underlying results are valid.
Atumnus Labs COAs are built to close each of these gaps by design. Methodology is documented per test. Instrument data is included. Chain of custody runs unbroken from submission through sign-off. Every COA is analyst-certified and includes the specification each result is evaluated against.
