Advancing Research with Precision
UK Peptide Lab supplies research peptides from stock held in the UK. We send our batches to an independent lab, publish the certificate on the product page, and give you the test number so you can check the result on the lab's own website before you order.

Check the result yourself. Don't take our word for it.
Anyone can write "lab tested" on a website. What matters is whether you can trace the vial in your hand to a report you can check with the lab. This is how we make that possible.
- 01
A batch number on every vial
The number printed on the label matches the certificate on the product page, so you know which report belongs to the vial in your hand.
- 02
Tested by an independent lab
We send vials from the batch to Janoshik Analytical for RP-HPLC purity and a measured amount per vial. Nothing is tested in-house.
- 03
Published as the lab issued it
The certificate goes on the product page unedited, with its Janoshik test number, so you can open the original on the lab's own website instead of trusting our copy.
- 04
More of the range every restock
We are moving the full catalogue to independent Janoshik testing. Products without a Janoshik report yet show the certificate supplied with that batch.
