IDUN Peptides COA Search Guide 2026: How to Find a Specific Batch, Lab Report or Test Method + LOOT30 Up to 30% Off
If you need a specific IDUN Peptides Certificate of Analysis, the fastest route is th
e company’s COA Library: search by peptide name, batch/lot number, testing lab, or test method, then compare the returned certificate with the lot information on the product or vial. IDUN currently says every batch has a COA, while its catalog lists 22 research compounds and identifies testing methods such as HPLC and LC-MS on individual products. The current promotion supplied for this guide is LOOT30, advertised as providing up to 30% off; verify the exact discount shown at checkout before paying.

IDUN Peptides COA Search: The Short Version
Use this sequence:
Start with the IDUN Peptides COA Library.
Search the exact compound name if you do not yet know the lot number.
If you have the vial or order information, search the exact batch/lot number.
Check the testing laboratory and report number.
Confirm that the certificate describes the same compound and lot you are researching.
Review the reported HPLC purity and any identity testing shown.
Check the test date and report date.
Download or save the certificate for your research records.
If the certificate cannot be matched, contact IDUN support before treating the documentation as verified.
Apply LOOT30 at checkout and confirm the final price and discount before completing the order.
That process is much more useful than simply searching for “99% purity.” A COA is batch-specific documentation; it is not a blanket guarantee about every vial, every storage condition, or every possible use.
What the IDUN Peptides COA Library Lets You Search
IDUN’s public COA Library is designed around batch documentation. Its search interface provides fields for peptide name, batch number, testing laboratory, method, minimum purity, and date range. It also offers comparison and download functions.
That makes the library useful for several different research workflows.
If you are starting with a compound name, search the peptide first and narrow the results by date or laboratory. If you already have a vial in front of you, the batch or lot number is the stronger starting point because it can narrow the search to the certificate associated with that particular production lot.
If you are comparing certificates from different periods, the test date can also matter. A certificate from an earlier lot is not automatically the certificate for a later purchase simply because the product name is identical.
Step 1: Find the Exact IDUN Peptides Product
Before searching a certificate, identify the exact product entry.
The current IDUN catalog shows 22 research compounds and includes categories such as cognitive compounds, GH secretagogues, longevity, melanocortin, tissue-repair peptides and solvents. The catalog currently lists products including GLP-3 RT, Selank, Tesamorelin, GLP-2 TZ, MOTS-c, NAD+ Buffered, GHK-Cu, BPC-157, Epitalon, Semax, SS-31, KPV, Ipamorelin, DSIP, Glutathione, Melanotan II, TB-500, CJC-1295 No DAC and PT-141, among others. Availability can change, so the catalog should be treated as the current snapshot rather than permanent inventory.
The important point is specificity. “MOTS-c” is not enough if you are trying to document a particular vial. You want the product identity plus the batch/lot identifier whenever possible.
Step 2: Search by Batch or Lot Number
If you have the physical vial, order record or product documentation, the batch/lot number is usually the most useful search term.
IDUN product pages state that COAs contain batch-specific information, and the company says COAs can also be accessed digitally through QR codes on vial labels.
A useful record includes:
Compound name
SKU, if available
Labeled quantity
Exact batch/lot number
COA/report number
Testing laboratory
Test date
Report date
This is much stronger documentation than saving only a screenshot that says “≥99%.”
Step 3: Match the Product Name and Lot
When you find a certificate, compare the certificate with the product you are researching.
The first question is simple: does the compound name match?
The second is more important: does the batch or lot match?
Third-party records illustrate why that matters. For example, a preserved IDUN MOTS-c certificate identifies lot MC10-260201, report number 2602050049, Freedom Diagnostics as the laboratory, and a reported average purity of 99.43%.
A separate IDUN CJC-1295 No DAC record identifies lot CJ10-260331 and report number 2604230223, with 99.78% HPLC purity and identity confirmation reported on the certificate.
Those are different products and different lots. You should not use one certificate as evidence for another simply because both are sold by the same supplier.
Step 4: Check the Testing Laboratory
The next question is who performed the analysis.
A useful COA should identify the testing laboratory clearly enough for the result to be understood or independently checked. IDUN's FAQ says its COAs include HPLC chromatographs, mass spectrometry data and purity assessments, and that the company uses independent third-party analytical testing.
Independent records also provide examples of laboratory-verifiable IDUN certificates. The MOTS-c certificate above is attributed to Freedom Diagnostics and includes a searchable report code.
This is an important distinction: “third-party tested” is a claim about a testing arrangement; the actual certificate is the document you should inspect.
Step 5: Understand HPLC Versus LC-MS on the Certificate
HPLC and LC-MS answer related but different questions.
HPLC, or high-performance liquid chromatography, is commonly used to separate components and quantify chromatographic purity. A purity figure such as 99.43% is therefore a measurement reported for the tested sample under the laboratory's stated method.
Mass spectrometry provides information used for molecular-mass or identity confirmation.
An IDUN MOTS-c certificate available through Freedom Diagnostics, for example, reports HPLC/UV analysis coupled with mass spectrometry and gives an average purity of 99.43%.
The practical takeaway is simple: do not reduce the entire certificate to one number. Read the method, identity information, sample details and reported result together.
Step 6: Check the Quantity Information Too
Some COAs include measured net peptide content in addition to purity.
That distinction matters because “purity” and “amount” are different measurements.
For example, the IDUN MOTS-c certificate reports two vial measurements of 11.81 mg and 11.62 mg, an average net peptide amount of 11.72 mg, and average purity of 99.43%.
That does not mean you should assume every IDUN vial has those numbers. They describe the tested samples associated with that particular report.
When saving a certificate, record both the labeled amount and any measured amount reported by the laboratory.
Step 7: Check the Test Date
The test date tells you when the submitted sample was analyzed.
It is useful when you are comparing certificates across different lots or trying to establish whether a document belongs to the production period you are researching.
A newer test is not automatically “better,” and an older test is not automatically invalid. The key is whether the certificate corresponds to the exact lot and whether the document contains enough information for your research records.
For example, the MOTS-c report was received February 5, 2026 and reported February 9, 2026.
Step 8: Look for Independent Verification Where Available
A useful extra step is checking whether the laboratory has a public verification surface or searchable report record.
For the MOTS-c example, the laboratory report provides a search code, and third-party databases have independently recorded the same report number and lot.
This is stronger than relying solely on an image uploaded to a product page because it gives you another place to cross-check the report identifier.
That said, independent verification still has limits. A COA can document what was tested; it does not automatically establish chain of custody for every vial sold, and it does not turn a research compound into an approved medicine.
Step 9: Save the Certificate With Your Own Records
For serious laboratory documentation, do not depend on a website remaining unchanged forever.
Save the certificate together with:
Product name
SKU
Batch/lot number
Order date
Labeled quantity
COA/report number
Laboratory
Test date
Report date
Relevant analytical results
Product-page URL
Date you downloaded the document
That creates a simple research documentation trail.
IDUN's public COA Library specifically supports downloading certificates, so using that feature is preferable to relying on a browser bookmark alone.
What a COA Can—and Cannot—Tell You
A good certificate can provide valuable evidence about a submitted sample.
Depending on the report, it may document:
HPLC purity
Mass-spectrometry identity
Net peptide content
Test date
Report number
Batch/lot
Laboratory
Additional analytical panels
But a COA is not a universal safety certificate.
For example, one independently preserved IDUN MOTS-c certificate documents purity and mass-identification information but does not provide results for sterility, endotoxins or heavy metals.
Another IDUN GLP-3 RT certificate preserved by PeptideBenchmark reports additional panels including sterility, endotoxin and heavy-metal information.
So the correct question is not “Does this peptide have a COA?”
It is:
“What does this specific COA actually document?”
A Practical IDUN Peptides COA Verification Checklist
Before treating a certificate as matched documentation, check:
Exact compound name
Exact batch/lot number
Labeled quantity
COA/report number
Testing laboratory
Test date
Report date
HPLC result
Identity/mass-spectrometry result
Any additional safety or composition panels
Whether the document can be independently cross-referenced
Whether the certificate corresponds to the lot you are actually researching
If one of those critical identifiers is missing or inconsistent, stop and resolve the discrepancy rather than filling the gap with assumptions.
