Research peptide lab results
Every third-party test report PeptideX1 has received, published as measured: batch number, content, purity by HPLC, and the laboratory's verification key so you can check the record yourself before you order.
[ Published reports ]
Five batches, five independent reports
All testing is performed by Janoshik Analytical on sealed vials submitted by PeptideX1. Results are reproduced here exactly as reported, including the one batch that came in under our 99% target. Each entry links to the original report image and to the laboratory's verification page.
99.7%
Report covers the 50 mg vial. The 100 mg presentation is a newer fill and will be listed when its batch report is back.
97.9%
This batch measured 97.9% purity, below the 99% figure we aim for. We publish the result as measured; the product page states the same number.
ID + amount
Ordered as an identity-and-amount test, so the report confirms what the vial holds rather than a purity percentage.

[ FAQ ]
Questions.
Who runs the tests?
Every report on this page was produced by Janoshik Analytical, an independent laboratory. PeptideX1 has no involvement in the analysis beyond submitting sealed vials.
How do I verify a report is genuine?
Each report carries a unique key. Enter it at janoshik.com/verify and the laboratory returns the original record, so the result you see here can be checked against the source.
Why are some products not listed yet?
A product is listed once its current batch has a completed third-party report. Products without a published report still ship with their batch Certificate of Analysis, and their reports are added here as they come back.
Why publish a result below 99%?
Because it is the measured result. The MOTS-c batch listed here tested at 97.9%, and the product page states the same number. Publishing the actual figure is the point of this page.
