How to read a Janoshik certificate of analysis

This note is about the document. A Janoshik certificate of analysis is one laboratory file. Nothing here is a direction for use.

What a COA is

A certificate of analysis is one test report for one sample from one lot. The laboratory received that sample, ran the method named on the report, and issued one file. The file does not cover other lots of the same compound, other vial sizes, or a later batch that uses a similar name. A new lot needs its own report.

The report does not make a compound a medicine. It does not approve the material or change what the listing is for. SOLUM AMINOS publishes a file only when that file is the one matched to the current listing. The catalogue line remains laboratory research material.

The fields on a Janoshik report

The task number sits at the top of the report. It is the laboratory’s identifier for that job. On the SOLUM AMINOS lot register the same number is printed in the Lot cell, with the word Janoshik in front of it. If two documents do not share that number, they are not the same job.

Three dates on the report are different dates. The order date is when the test was ordered. The sample-received date is when the laboratory recorded the sample as received. The analysis date is when the laboratory says the analysis was done. A register may show only one of those dates in its Tested cell. That cell is the date stored for the row. It is not a claim that the other two dates fell on the same day.

Client is who paid for the test. It names the account that commissioned the work. It is not a finding about the sample, and it is not the name of the laboratory. Sample is what the submitter said the material was. That line is a label supplied with the sample, not a result the chromatograph produced. Batch is the batch identifier the report carries. It is separate from the task number. Results are the measured figures for that run. Comments are the laboratory’s notes, when the report has a comments line.

The unique key sits at the bottom of the report. It is the code issued so this file can be looked up. A task number without the key, or a key without the task number, is not enough for the laboratory’s own check. Both identifiers belong to that one report.

Purity versus content

Purity, written as a percentage, is the main peak’s share of what the HPLC run detected. It describes the composition of the material the detector saw on that run. It does not say how many milligrams were in the vial. A purity figure applies only to the task number on that report.

Content is the measured mass, in milligrams, reported for that sample. It can differ from the mass printed on the label. A listing that says 10 mg can have a file whose content line is not 10 mg. The label is what the catalogue states. The content line is what that report measured. They are not the same field.

Blends are reported as a mass per component. A blend file lists those component masses and has no single purity figure. That is why some rows on the lot register say “See file” in the Purity cell. The file is published. It does not contain one percentage that could be copied into the cell. Open the file for the component masses. Do not read “See file” as a purity of its own.

How to verify a report

Verification uses the laboratory’s page. Enter the task number and the unique key at janoshik.com/verification. Type the unique key in capital letters, as it is printed. If the report has a QR code, scanning that code is the same check. The code points at the same verification record.

When the laboratory’s copy opens, compare it with the file SOLUM AMINOS publishes, line by line. Task number, key, sample, batch, dates, results, and comments should be the same lines. A match is the two documents agreeing. A mismatch means the published file is not that verified copy. A report that does not carry both the task number and the unique key cannot be verified.

How to match your vial

The number that matters on the object is the task number printed on the vial. Check that number against the Lot cell on the lot register. The cell is written as Janoshik followed by the task number. The same number has to be on the label and in that cell. A matching compound name, or a matching vial size, is not the same check.

If the number on the label is not in the table, the register does not have a published file for that vial. Email hello@solumaminos.com.au with the order number and the number on the label. Do not borrow a row from another task number.

A worked example

The published Retatrutide 10 mg row is the example. The figures in this section are the ones already stored for that row on the lot register. They are not taken from another source. The Lot cell is Janoshik #227712. The Tested cell is 14 Sep 2026. The Purity cell is 99.659%. The measured mass on that file, the content line, is 11.03 mg. The unique key on that file is D5CF672HVD64. Those are the task number, the test date held on the register, the purity, the measured mass, and the key. They belong to that task number only. They do not describe another retatrutide lot or another compound.

If a vial’s label shows a different task number, this example is not its certificate.
