Questions

Frequently asked questions

Everything qualified researchers ask before ordering. Still unsure? Our team replies within one business day.

How is purity tested and documented?
Each lot is analysed by an independent laboratory using HPLC and mass spectrometry to confirm identity and purity to a documented ≥99% standard. Results are published as a lot-specific Certificate of Analysis that you can download by batch number before or after purchase.
How fast do orders ship?
In-stock orders placed before 2pm (UK time) on a working day are dispatched the same day by tracked delivery. Orders over £60 ship free.
How should peptides be stored on arrival?
Lyophilised material should be kept sealed, dry and away from light, refrigerated at 2 to 8°C for short-term storage or frozen for longer periods. Storage guidance is printed on every COA.
What is your purity guarantee and return policy?
If an independent result for your lot falls below the specification stated on its COA, contact us with your batch number and we will replace the material or refund it in full.
Do I need an account to order?
No. Guest checkout is available, but a free account gives you order history, saved COAs, restock alerts and volume pricing for research labs.
