What is on the report
- Task number: the laboratory's reference for the job.
- Sample and client: what the sample was submitted as, and who sent it in.
- Tests requested: the line that sets the report's scope. Read it first.
- Results: each figure with its unit, for the tests requested and nothing else.
- Dates: when the sample was ordered, received and analysed.
- Unique key: the code that, with the task number, opens the laboratory's copy.
Looking it up at the laboratory
The lookup address is the laboratory's base address followed by the task number, an underscore and the key: https://verify.janoshik.com/tests/task_key. Type the address yourself, or use the COA Reader, which builds it from the two values. Do not rely on a link supplied alongside a document: the point is to reach the laboratory's record by a route the document did not choose. If the address shows no record, or a record that differs from the document, the document is not the laboratory's report as issued.
What to compare
- Compound
- The sample name on the laboratory's record should be the compound on the vial, not a related one.
- Batch
- The batch on the record should match the batch printed on the vial in hand. A report for another batch says nothing about this one.
- What the test covers
- An endotoxin test says nothing about identity or purity; an identity test says nothing about endotoxin. Read the tests requested line.
- The figure and its unit
- The result should match what the seller quotes, in the same unit. Per vial, per mg and per mL are not interchangeable.
- Dates
- Check the order, receipt and analysis dates, and that the analysis is recent enough to describe the stock being sold.
- Client name
- The client on the record is who sent the sample. It tells you who commissioned the test, not who made the product.
What each result shows
- Identity
- An identity test checks that the substance is the compound named. Mass spectrometry measures the molecule's mass directly; an HPLC identity check compares how long the sample takes to pass through a column against a reference standard, which is weaker evidence on its own.
- Purity
- A purity result, usually by HPLC, is the share of the detected material that is the target compound. It does not by itself prove what that compound is, which is why purity is normally paired with an identity test.
- Amount in the vial
- A quantity result states how much of the compound the vial holds, usually in milligrams. A vial can be pure and still hold less than its label says.
- Endotoxin
- An endotoxin test, usually the LAL assay, measures bacterial endotoxin in endotoxin units. It does not show identity, amount or purity.
HPLC separates a sample into its components; the time a peak emerges identifies it against a reference standard and the peak's area gives its quantity, while a mass spectrometric detector adds the mass information that identifies a compound directly[2]. Endotoxin is measured with the bacterial endotoxins test, by gel clot, photometric or kinetic methods[1]. For what an endotoxin figure and its unit mean, read reading an endotoxin result rather than a summary here.
Primara Labs' published reports
Retatrutide batch RETA-4728-A is Janoshik-tested for bacterial endotoxin: 6.066 EU per vial, analysed 21 September 2026 (task 234146, key H2KI86I8GWB4). This report covers bacterial endotoxin only. It does not establish identity or purity.
