We don’t ask you to take our word for what’s in the vial. Our peptides come with independent analysis from Janoshik, a laboratory that specialises in peptide testing, and we publish the certificates here so you can read them before you order.
Each certificate shows the peptide, the measured content of the vial, the purity, and the date it was tested. The supplier’s identifying details are blacked out, which is the standard way to protect the supply chain, while every figure you need to assess the result stays in full view.
The certificates below are provided for your reference, not as medical or therapeutic claims. All products are supplied for laboratory research use only.
