How long does delivery take?
Orders dispatch the next UK business day. UK 1-2 days, EU 2-4 days, rest of world 3-8 days. Free cold-chain shipping on every order. See the shipping tab above for full transit times by country.
How are the pens packaged?
In an insulated cold-chain box with gel packs and a temperature indicator card. Tracked door-to-door via DHL Express or FedEx. The outer label is plain, with no product references.
How should I store the pens after delivery?
Refrigerate at 2 to 8 °C, away from direct light. Once the seal is broken, refrigerate and use within the stability window noted on the product page. Do not freeze.
Do orders include a certificate of analysis?
Yes. Every lot is independently tested by Janoshik Analytical. An HPLC purity certificate and a separate aqueous pH certificate are published before each lot ships. Both are linked in the lab certificates tab above.
What if my package arrives damaged?
Send a photo of the box, tamper seal and indicator card on WhatsApp within 24 hours of delivery. We replace cold-chain failures the same business day, free of charge. No return needed.
How do payments work?
Payment is completed through a secure payment link on WhatsApp. Once you place an order, we open a short WhatsApp thread to verify the buyer and keep the research-use attestation and the order on one record. After verification, we send the secure payment link.
