What the numbers mean
Purity, identity and quantity are three different measurements. Our guide walks through a Janoshik report line by line so you know what to look for from any vendor.
Read the guideJanoshik is an independent analytical laboratory in the Czech Republic that tests peptides and other research compounds submitted by clients. Each report carries a unique ID that can be verified on verify.janoshik.com.
Typically HPLC purity (the percentage of the main peak against all peaks), mass spectrometry to confirm identity, and where requested, quantity per vial or pen. Our target standard is over 99% purity.
