1. Returns
Unopened, undamaged products with an intact tamper seal may be returned within 14 days of delivery. Contact us first — returns sent without prior agreement cannot be processed.
2. What we cannot accept
- Opened vials, or vials with a broken seal — for safety and batch traceability, these can never be resold.
- Products stored outside 2–8 °C after delivery, where cold chain cannot be evidenced.
- Private-label and custom-produced batches, which are made to order.
- Products returned after 14 days from delivery.
3. Damaged, wrong or missing items
If a parcel arrives damaged, photograph the outer box and contents before unpacking further, and contact us within 7 days. If you receive the wrong item, or an item is missing, we replace it or refund it in full, including shipping. If tracking stops for more than 10 business days we open a carrier investigation.
4. Batch quality
If an independent re-analysis shows a batch does not meet the purity stated on its certificate of analysis, we refund or replace it in full, and withdraw the batch. Send us the report and the LOT number.
5. Cancellations
Orders can be cancelled at no cost before dispatch. Once tracking is issued the order is in transit and the return process above applies. Subscriptions can be cancelled at any time before the next renewal.
6. How refunds are issued
Refunds go back to the original payment method within 5–10 business days of us receiving and inspecting the return. Original shipping is refunded only where the fault was ours. Return shipping is at your cost unless the item was damaged, wrong or defective.
