Our standards
Quality you can verify — not just claim.
Every production lot is analysed by an independent, accredited laboratory before release. Purity by HPLC, identity by mass spectrometry, reported against a certified reference standard — measured values, not theoretical targets. Batches below our 99% threshold are destroyed, never sold.
Quality & testing standardsSynthesis
Produced to specification and lyophilised for long-term stability in transit and storage.
Independent testing
Purity by HPLC, identity by LC-MS — verified by an accredited third-party lab on every lot.
Cold-chain dispatch
Insulated mailers with gel ice packs, dispatched the same working day from our UK hub.
Your bench
Tracked delivery, with the batch certificate of analysis tied to the lot number on your vial.
