We make the data public before you order. Every peptide we stock is sent to an independent lab for HPLC analysis — the full results are posted so you can check purity and identity without having to take anyone's word for it.
Just Peptides was set up around one straightforward principle: researchers deserve access to real data, not marketing claims. We stock a focused range of research-grade peptides and compounds, handled with documentation at every step — nothing hidden between the lab and your door.
Before each batch goes live for sale, it goes through independent HPLC testing. The results — purity percentage, identity confirmation, and batch reference — are posted publicly on our Quality archive. If the numbers aren't there, the product isn't available to order.
That standard applies to everything we carry. No exceptions for new products, no shortcuts under pressure. If a batch doesn't pass, it doesn't ship — full stop.
The test report for every batch is published before the product goes live. Check purity and identity figures for anything in our range — before you spend a cent.
We photograph each vial at the point of testing — cap colour, vial size, and label are documented in the COA. What's in the report is what gets sent to you.
Each dispatch is tied to a unique batch ID that links back to a published test result. The peptide reaching your lab can be traced all the way back to independent analysis.
Every order ships with full tracking. Parcel missing or arrives damaged — we don't ask questions. A replacement goes out or store credit is issued. That's it.
We don't test in-house. Every batch is sent to an external laboratory for HPLC analysis before it's listed for sale. That means the purity figures on our site come from a lab we don't control — and that's exactly the point. The full COA, including tested-vial photograph, goes onto our public archive. You're reading the lab's numbers, not ours.
External lab. Public results. No exceptions.
