Trust in research reagents cannot be assumed; it must be proven. This is the four-step framework we use to guarantee the integrity of every vial we supply.
We do not manufacture compounds in-house. Our primary value is in aggressive curation. We source exclusively from primary synthesis facilities operating under strict ISO 9001 or cGMP quality management systems.
Before any supplier is onboarded, they must provide their own raw material testing data, facility certification, and undergo a trial batch verification. If a facility's internal CoA does not perfectly match our independent re-test results in the UK, that facility is permanently disqualified from our supply chain.
"A supplier's own internal Certificate of Analysis is a marketing document. Only an independent, third-party laboratory report constitutes proof."
Every single batch we receive is quarantined upon arrival in the UK. We extract a random sample vial from the batch and submit it to an independent analytical laboratory.
If a batch fails to meet the ≥98.0% purity threshold, the entire batch is destroyed. We never blend or dilute failing batches.
A 99% pure peptide that degrades in a hot warehouse is a ruined experiment. Temperature control is as important as the synthesis itself.
All inventory is stored in monitored, commercial-grade freezers at −20°C. Vials are only removed from cold storage at the exact moment of dispatch.
For dispatch, we utilise insulated EPS shippers with validated cold packs. This maintains a stable, cool environment during transit, preventing the temperature fluctuations that cause rapid lyophilised peptide degradation. Next-day tracked courier services ensure time-in-transit is minimised.
We believe in absolute transparency. Your physical vial will have a Batch Code printed on the label (e.g., PV-2609-A).
By entering this code into our Batch Lookup tool, you can instantly download the specific Certificate of Analysis for your exact vial. This document contains the actual HPLC chromatogram and MS data, the name of the independent laboratory that performed the test, and the date the test was conducted.
