Free tracked UK shipping over £150 · Third-party tested, minimum 99% purity

Quality

Independent testing on every lot

Purity claims mean nothing without documentation. Here is exactly what happens between synthesis and dispatch.

HPLC purity

Reverse-phase HPLC quantifies the target peptide against related impurities. Minimum specification is 99%.

Mass spectrometry

Molecular weight confirmation verifies that the sequence in the vial is the sequence on the label.

Certificate of analysis

Every lot ships with a batch-specific COA covering appearance, purity, identity and net peptide content.

Batch traceability

Lot numbers are printed on each vial so results can be traced back to the exact production run.

Requesting a COA

The COA for your batch is included with your shipment. If you need it in advance for a procurement or ethics submission, email the product name and lot number to our team and we will send the PDF the same working day.

Retained samples

We retain a sealed sample from every production lot so results can be independently re-verified if a discrepancy is ever reported.
