Our home
We work from the UK's largest single-site life sciences campus: 400 acres of laboratories, cleanrooms and testing facilities originally built as a global pharmaceutical R&D headquarters. That means cold storage, careful handling and accredited testing partners are all on the same site as our stock.
Delivery & handling
Place your order online. Orders before 3pm on a working day are picked and packed the same day.
Your vials are pulled from a batch with a published CoA and sealed in plain, unbranded outer packaging.
Dispatched on a tracked 24-hour Royal Mail service. Free on orders over £100, with tracking.
Add bacteriostatic water down the vial wall, swirl gently, then keep it in the fridge (2–8°C) and use within 30 days.
Third-party testing
We check purity with a lab technique called HPLC, confirm the peptide's identity with mass spectrometry, and screen every batch for contamination and sterility. The certificate carries the same batch number printed on your vial, so you can check exactly what you received, not just a sample from another batch.
Why researchers choose us
No vial is released until an independent laboratory confirms the batch meets our 99% purity standard.
Everything is made, filled and documented for laboratory research, with the specs and paperwork coming before any marketing.
All of our peptides are picked and packed from the UK's largest life sciences campus, and shipped with tracking.
Every release is held to the same specification, so a repeat order behaves like the last one.
