To verify a Freedom Diagnostics certificate of analysis, enter the Search Code printed on the report at FreedomDiagnosticsTesting.com, then compare the laboratory's record with your copy line by line: compound, lot, dates and results. The Search Code sits in the identifier table at the top right of the certificate; enter it exactly as printed. The lookup confirms that the laboratory holds a document under that code and opens the laboratory's own copy of it. It does not repeat any analysis, and it does not show that a particular container came from the tested lot.
Glow Peptides' lot records are where its lot documentation sits, and a certificate names the laboratory that issued it. The steps that follow apply to certificates issued by Freedom Diagnostics and use the laboratory's own field labels, instructions and messages, read from its public pages on October 4, 2026. A closing section covers certificates issued by Bioviridian. No identifier from any certificate appears on this page; fields are named by the labels the certificates print.
Where is the Freedom Diagnostics certificate lookup, and what does it accept?
Freedom Diagnostics publishes a page titled Certificate of Analysis Lookup on its own website. It is reached from the COA Look Up item in the site menu, or directly at freedomdiagnosticstesting.com, Certificate of Analysis Lookup. The page heading reads Certificate of Analysis Lookup.
Verification of a single certificate runs through the tab labeled Search Code / Accession #. It holds one text box and a button labeled Look up. The box accepts up to 40 characters, no account or login is needed, and the page states two input rules in its own words: codes are not case-sensitive, and any spaces should be removed.
Freedom Diagnostics certificates are checked through a public Certificate of Analysis Lookup on the laboratory's own website. Under the tab labeled Search Code / Accession #, one code and the Look up button return either the laboratory's own copy of a matching document, behind an Open PDF button, or a message saying why no document opened.
Reach the page by typing the laboratory's address or choosing COA Look Up from its menu, not through a link, QR code or hosted file that arrived with the certificate. The certificate itself prints the line Searchable via: FreedomDiagnosticsTesting.com as plain text rather than a link, so the route a reader types is the same route the certificate names. The same rule holds for a report from any laboratory; the general steps for verifying a shared lab report cover it.
Which identifiers on a Freedom Diagnostics certificate does the lookup use?
The identifiers sit in a table at the top right of the first page. The lookup page says where to look in its own instructions: find the Search Code field in the top right table of the CoA, where it is labeled exactly as Search Code. The same table holds the other identifiers a comparison needs.
| Label as printed | What it identifies | How it is used |
|---|---|---|
| Accession Number | The laboratory's number for the submitted sample, assigned when the sample is received and accessioned | Accepted by the lookup on its own, but it can match more than one document |
| Client | The company that submitted the sample, as entered on the laboratory's submission form | Compare it with your copy |
| Search Code | The lookup key the laboratory's page asks for | Enter it in the lookup exactly as printed |
| Received Date | When the laboratory received the sample | Compare it with your copy; it is a different date from the report date |
| Reported Date | When the laboratory reported the analysis | Compare it with your copy |
| Product | The sample name the client entered | Compare it with your copy |
| Lot | The lot or batch identifier the client entered for the sample | Ties the document to a container; compare it with the container label |
| COA | The certificate number | Compare it with your copy |
On a Freedom Diagnostics certificate, the Search Code is the lookup key printed in the identifier table at the top right of the first page, and the laboratory's instruction is to use it exactly as printed. The Accession Number in the same table is the laboratory's number for the submitted sample, and the Lot field holds the lot the client entered, which ties the document to a container.
Labels vary slightly between certificate templates. A later template read for this guide prints Accession # and Received: where the earlier one prints Accession Number and Received Date. Whatever the template, the lookup page's own instruction is to use the field labeled Search Code.
Two of those fields carry most of the weight, and they answer different questions. The Search Code names the laboratory's document, so it is what the lookup takes. The Lot names the material the client says the sample came from, so it is what ties the document to a container. A Search Code never stands in for a lot number, and a lot number does not find a document in this lookup.
The laboratory's submission form explains where the Client, Product and Lot fields come from: COA information is generated from the details submitted on this form and verified against the sample received, and samples are accessioned on receipt. Those three fields carry what the submitting company entered; the Accession Number and Search Code are the laboratory's own.
What do the Freedom Diagnostics lookup's messages mean?
The lookup answers every search with one of five responses, and each calls for a different next step. The wording below is the laboratory's own, from its lookup page.
| Response on the page | What it means | Next step |
|---|---|---|
| A result card with the status Document found and a button labeled Open PDF | The laboratory holds a document under the code entered | Open the PDF and compare it with your copy, field by field |
| No document found for, followed by the code entered | Nothing matched that code | The page's advice: double-check the Search Code on your CoA and try again, then contact the laboratory if the issue persists |
| Multiple CoAs found for accession number, followed by the number entered | An accession number on its own matched more than one document | The page's instruction: Please use your full Search Code printed on your CoA |
| Too many lookups from your connection | The page limits how many searches one connection can make | The page's advice: wait a minute and try again; this says nothing about any certificate |
| Connection error, with the line Could not reach the document server | The page could not reach the laboratory's document server | The page's advice: try again in a moment; this says nothing about any certificate |
The Freedom Diagnostics lookup returns one of five responses: Document found with an Open PDF button, No document found for the code entered, Multiple CoAs found for an accession number, Too many lookups from your connection, or a connection error. Only Document found opens the laboratory's copy; the other four call for rechecking the code, entering the full Search Code, or trying again later.
Why does the lookup ask for the full Search Code rather than the accession number alone?
The Search Code / Accession # tab accepts either code, but an accession number on its own can match more than one document. When it does, the page answers with a message that begins Multiple CoAs found for accession number, followed by the instruction: Please use your full Search Code printed on your CoA. The dependable input is therefore the full Search Code, entered exactly as it is printed on the certificate.
Use the full Freedom Diagnostics Search Code, exactly as printed on the certificate. The lookup accepts an accession number by itself, but when that number matches more than one certificate, the laboratory asks for the full Search Code printed on the certificate instead.
Some certificates run to more than one page, and a page that reports a separate test can carry its own Accession Number and Search Code. A lookup of one page's code confirms that page only, so look up every Search Code printed on the document you are relying on.
What should match between the laboratory's copy and your copy?
A successful lookup shows a result card with the document code, the line Issuer: Freedom Diagnostics Testing, the status Document found, and a button labeled Open PDF. The card itself shows no analytical results. The comparison happens between the PDF that button opens and the copy you were given. The laboratory serves that PDF from its own document host, coas.freedomdiagnosticstesting.com, so the address bar shows that the file came from the laboratory.
| Field | What to compare | What a difference means |
|---|---|---|
| Search Code and Accession Number | Every character, exactly as printed | A different document or a transcription error; recheck the code first |
| Client | The full name | The certificate was issued to a different client than the copy suggests |
| Product | The sample name | The document describes a different sample |
| Lot | Letters and digits | The document may describe a different lot; ask the issuer |
| Received Date and Reported Date | Both dates, separately | A different issue of the document; keep both versions |
| Method statement | The wording of the method line | Reported values may come from a different method |
| Reported values | Each value, its unit and its basis | The two copies are not the same document; the laboratory's copy is the reference, and the difference is a question for the issuer |
| Signatory and images | The signatory's name and title, and any image the certificate carries | Layout changes need an explanation from the issuer |
Two copies of one certificate should agree in every field, because they are the same document. Matching a certificate to a container is a different comparison with its own rule. Glow's guide to reading a peptide lot number explains its lot format and states the rule it applies: compare the characters, ignore the hyphens. Glow's own lot matching also counts a trailing run number such as -01 that a certificate prints after the lot as part of the same lot.
The laboratory's copy of a Freedom Diagnostics certificate and your copy should agree on the Search Code, client, product, lot, received and reported dates, method line and every reported value. Any difference is a finding to record and raise with the issuer, not a typo to correct by eye, because only the laboratory's copy came from the laboratory.
What does a successful lookup establish, and what does it leave open?
A match establishes three things:
- the laboratory holds a document under that Search Code;
- the document was issued to the client named on it;
- your copy agrees with the laboratory's copy field by field, so the copy you hold is the document the laboratory serves under that code.
A match does not establish that a particular container came from the sampled lot. That link runs through three records outside the laboratory: the lot printed on the container label, the lot on the certificate, and the supplier's records connecting the two. The lot traceability worksheet shows how to record each link with its evidence. Among the laboratory's own services, the one that looks beyond a single container is conformity testing, which its home page describes as testing additional vials from the same lot to confirm they match; a certificate speaks to that question only when it reports that test.
The certificate's own disclaimer sets the scope of its results. Both Freedom Diagnostics certificate templates read for this guide state that the analysis is intended for informational purposes only and is specific to the sample(s) provided, and that the accuracy and reliability of the test may be influenced by sample integrity, handling and other experimental variables. A result describes the submitted sample. It does not describe every container in a lot.
A matching Freedom Diagnostics lookup shows that the laboratory issued the document you hold and that your copy matches the laboratory's own copy. It does not show that your container came from the sampled lot, and it does not extend the result beyond the sample the laboratory received; the lot printed on the label and the supplier's records cover that link.
The laboratory's submission form adds one more fact that bears on disputes. Under the heading COA Release Policy, it states that once a COA has been released, company names, sample names, lot numbers, and identifying information may not be retroactively modified. A copy whose identifying fields differ from the laboratory's released copy therefore raises a question for the issuer; a later correction at the laboratory would not explain it.
What testing does Freedom Diagnostics describe on its own website?
The laboratory's home page lists its services under the heading What we test. In the laboratory's words, Purity (HPLC) measures how pure your sample is, reported as a percentage, and Identity (LC-MS) confirms by molecular mass that the compound is what the label says. The same page states that every COA includes both HPLC purity and LC-MS identity confirmation.
The certificate read for this guide carries a matching method line: All Chemical Analysis was performed by HPLC with UV Detection Coupled with Mass Spectrometry. A later template prints it as Method: HPLC with UV detection coupled with mass spectrometry (LC-MS). A purity percentage and an identity confirmation answer different questions. Purity describes how much of the detected signal belongs to the main component; identity describes whether the measured mass fits the named compound. The guide to HPLC and mass spectrometry explains both methods, and the COA interpretation guide shows how to record what each reported value does and does not cover.
The same list includes further services that a client chooses per sample, including net content, endotoxins, a PCR-based test the laboratory lists as Sterility (PCR), conformity testing of additional containers from the same lot, heavy metals, and pH on request. Because each service is chosen at submission, a certificate reports only the tests that were requested for that sample. An absent test is a test that was not reported, not a test that failed, and nothing about an absent test can be read from the certificate.
Freedom Diagnostics describes HPLC purity and LC-MS identity as the two measurements every certificate includes. Other services, such as net content or endotoxins, are chosen by the client for each sample, so a given certificate reports only the tests that were requested for that sample and says nothing about tests that were not.
What should you do when the lookup finds nothing or a different document?
A no-match result reads No document found for, followed by the code that was searched, and the page advises double-checking the Search Code on the certificate and trying again, then contacting the laboratory if the issue persists. The laboratory's contact page is linked from its menu. Before recording a miss as a finding, rule out a transcription error: the letter O typed for a zero, the letter I for a one, or a missing digit.
If the code is correct and still finds nothing, or opens a document that differs from your copy, stop and record the discrepancy instead of resolving it. Write down the code exactly as typed, the date and time, the message or document returned, and every field that differs. The lot traceability worksheet shows how to write that record so a second reviewer can repeat it. Then ask the laboratory, and the supplier that provided the copy, which document is current.
When a correct Freedom Diagnostics Search Code finds no document, or opens one that differs from your copy, the certificate is unverified rather than disproved. Record the code, the date, the response and every differing field, then ask the laboratory and the supplier that provided the copy which document is current.
How do you verify a Bioviridian certificate?
Bioviridian certificates use a different identifier and a different lookup. The certificate prints a field labeled Web Verification Code near the top, and at the foot of the page the line Visit: https://bioviridians.com/coa-search.html beside a QR code. The laboratory's COA Search page asks the reader to enter your COA number to access your Certificate of Analysis, under a field labeled COA Number, with a button labeled Search. Enter the Web Verification Code exactly as it is printed.
A match opens the laboratory's own file in a viewer titled Certificate of Analysis, with buttons to download the file or open it full screen. A miss returns the message No COA found for, followed by the code, with the instruction Please check the number and try again; if the file cannot be loaded, the page reads There was a problem loading the COA. Please try again later. As with Freedom Diagnostics, type the address rather than scanning the code printed on a copy, then compare the laboratory's file with yours.
| Label as printed | What it holds |
|---|---|
| Web Verification Code | The lookup code; enter it exactly as printed |
| Sample Received and COA Issued | Two dates, with the month spelled out |
| Vendor | The vendor named on the certificate |
| Sample Name and Lot Number | The sample and lot as submitted |
| Methods | Identity: Confirmed via LC-MS; Purity: RP-HPLC (214 nm); Content: HPLC quantitation |
To verify a Bioviridian certificate, enter the Web Verification Code exactly as printed on it at the laboratory's COA Search page on bioviridians.com, open the laboratory's own file, and compare its sample name, lot number, dates, methods and reported values with your copy.
Frequently asked questions
Can I verify a Freedom Diagnostics certificate with only the accession number?
Sometimes. The lookup's Search Code / Accession # tab accepts an accession number by itself, but when that number matches more than one document the laboratory asks for the full Search Code printed on the certificate. Entering the full Search Code exactly as printed avoids that step.
Is the Search Code the same as the lot number?
No. The Search Code identifies the laboratory's document and is printed in the identifier table at the top right of the certificate. The lot number identifies the material the sample came from, as the client entered it. The lookup uses the Search Code; matching a container uses the lot.
Does a matching lookup prove my container came from the tested lot?
No. A matching lookup shows that the laboratory issued the document and that your copy matches the laboratory's copy. Whether a container came from the sampled lot depends on the lot printed on the container label, the lot on the certificate, and the supplier's records connecting them.
Why look a certificate up at the laboratory instead of relying on a PDF from a seller?
A PDF is a copy, and copies can be edited or attached to the wrong product. The laboratory's lookup opens the laboratory's own copy, so a field-by-field match shows that your copy is the document the laboratory holds. Reach the lookup by typing the laboratory's address rather than following a link that came with the copy.
What if the laboratory's PDF and my copy differ?
Record both versions and every field that differs, with the date, and ask the laboratory and the supplier which document is current. Freedom Diagnostics' submission form states that identifying information on a released certificate may not be retroactively modified, so a difference in those fields is a question for the issuer.
Do I need an account to use either laboratory's lookup?
No. The Freedom Diagnostics Certificate of Analysis Lookup and the Bioviridian COA Search are public pages that take a code and open the laboratory's own copy of a matching certificate without a login or an account.
Sources and scope notes
Field labels, instructions and messages are quoted or closely paraphrased from the Freedom Diagnostics Certificate of Analysis Lookup page, home page, contact page and sample submission form, and from the Bioviridian COA Search page, all read with ordinary page requests on October 4, 2026. No lookup was submitted while preparing this guide. Laboratories change their pages, so the labels a reader sees later may differ.
Certificate field labels come from two Freedom Diagnostics certificates, one in each template described above, and one Bioviridian certificate, read on October 4, 2026. No lot, accession number, Search Code, verification code, date or reported value from any certificate is reproduced.
Describing a laboratory's lookup is not an assessment of the laboratory's methods, accreditation or results, and a matching lookup is not a reviewed finding about any lot.
Glow Peptides, which publishes this guide, is a client of laboratories that issue certificates of this kind. Nothing here establishes which laboratory performed the testing for any particular lot.
