From vial to published report

Three steps between a vial and the result on this page.

  1. 01

    A sample goes to the lab

    A vial is sent to Janoshik Analytical. Purity is measured by HPLC and identity is confirmed by mass spectrometry.

  2. 02

    The lab issues the certificate

    The report records the compound identified, the purity measured, the test number and the dates the sample was received and analysed.

  3. 03

    It is published here

    Each certificate appears on this page and on its product page, so you can read the result before you pay.

How to read a certificate

Test number and QR code
The lab's reference for the job. On newer reports the QR code opens the same certificate on janoshik.com, so you can confirm it has not been altered.
Sample
The compound as it was submitted for testing.
Results
The compound the lab identified by mass spectrometry, and its purity by HPLC as a percentage.
Dates
When the lab received the sample and when the analysis was carried out.
Sign-off
The analyst's signature for the laboratory.

Questions about testing

Still unsure about a result? Ask us and an Australian team member will walk you through the report.

What is a certificate of analysis?

A certificate of analysis (COA) is a laboratory's record of a tested sample. It names the compound the lab identified, the purity it measured, the test number and the dates the sample was received and analysed.

Who tests NuVion peptides?

Samples are tested by Janoshik Analytical, an independent analytical laboratory. Purity is measured by HPLC and identity is confirmed by mass spectrometry. Each certificate is published on this page and on the product page.

How do I verify a certificate?

Newer reports carry a test number and a QR code. Open the Verify link on the certificate card, or scan the code, and the same report loads on janoshik.com.

What does the purity percentage mean?

HPLC separates everything in the sample and measures each component. Purity is the share of that signal that belongs to the target peptide, so 99.50% means 0.50% of what the lab detected was something else, such as a shorter fragment of the same sequence.

Why are some results shown in IU instead of purity?

HCG is a glycoprotein hormone, so Janoshik Analytical reports its strength in International Units (IU) rather than as a peptide purity percentage. The card shows the IU measured and the strength of the vial tested.

Is every product tested?

Not every product has a published certificate yet. New reports are added as samples are tested, and every certificate here shows the date of its test so you can see how recent it is.

Can I download the results?

Yes. Every result on this page is available as CSV and JSON, with the compound, purity, test date, laboratory, test number and a link to the full certificate.
