COA's are the most important part of the peptide world. They are the backbone of knowing what is pure and, more importantly, what is accurate.
The process of ordering peptides is simple. The order is placed, the manufacturer ships — but only legitimate manufacturers provide COA's. These documents are verifiable, and companies like JanoShik have been around since 2006.
Make sure to verify COA's first before purchasing!
Each vial carries a holographic label with a unique Task# (e.g. Task#168390). That number matches the Task Number on the corresponding Janoshik test report — so you can cross-reference the vial in your hand against the lab results below.
