How to Read Janoshik Lab Reports
A Guide to Peptide Purity & Verification
In the world of grey market peptides, testing is everything. Janoshik Analytics is the gold standard for third-party verification. Learn how to interpret HPLC and MS reports to ensure your research stays safe.
Key Components of a Janoshik Report
1. HPLC (Purity)
High-Performance Liquid Chromatography measures the purity of the peptide. Look for a purity percentage of 99% or higher. A lower percentage may indicate systemic impurities or manufacturing bypasses.
2. Mass Spectrometry (Identity)
Mass Spectrometry confirms that the substance is actually the peptide it claims to be (e.g., Tirzepatide or Retatrutide). It measures the molecular weight to verify identity.
3. Potency (Quantity)
Potency tells you how many milligrams are actually in the vial. If you bought a 5mg vial but the report says 4.2mg, the product is under-dosed.
Janoshik FAQ
How do I verify a report on the Janoshik website?
Every legitimate report has a unique task ID and key. You can enter these on Janoshik.com to verify that the report has not been tampered with or photoshopped.
What is a "blind test"?
A blind test is when a researcher sends a sample to Janoshik without the vendor knowing, providing the most unbiased results possible.
Can I track my test results in Shotlee?
Shotlee allows you to log specific batches and notes, making it easy to keep track of which Janoshik reports correspond to your current research protocol.
