Janoshik Verified Reports

Every peptide we supply is independently tested and verified to a minimum of 99% purity. We don't ask you to take our word for it. Each batch is sent to Janoshik Analytical, an independent laboratory based in Prague, Czech Republic, that specialises in analytical testing for the research peptide industry.

Independent Testing

Janoshik is one of the most respected independent testing laboratories in the field. Every batch we stock is analysed for both purity and identity before it ever reaches you, so you can be confident that what is printed on the label is exactly what is in the vial. Our standard across the entire range is a minimum of 99% purity.

Requesting a Report

We are happy to share the verified report for the specific peptide you purchased. To request it, head to our contact page and send us a message through the contact form with your order number and the product you would like the report for. Our team will get the relevant Janoshik report over to you directly.

Why Reports Are Not Public

You might wonder why we don't simply publish every report on the website. Unfortunately, publicly available test reports are frequently copied, tampered with, and used illegally by other retailers to misrepresent the quality of their own products.

We take real pride in our work and in the integrity of our testing, so we share reports privately, on request, and tied to a genuine order. Keeping our results out of the public domain is how we protect both our customers and the honesty of what we stand behind.
