Research materials
All products are supplied for in-vitro laboratory research use only. Because of the nature of lyophilised research compounds, we cannot accept returns of opened vials or products that have left our cold-chain control.
Damaged or incorrect orders
If your parcel arrives damaged, incomplete, or containing the wrong item, contact us within 48 hours of delivery with your order number and clear photos of the packaging and product. We will arrange a replacement or refund at our discretion.
Lost parcels
If tracking shows no delivery after the expected window, contact support. We will investigate with the carrier and replace or refund once loss is confirmed.
Quality concerns
Every batch is independently HPLC-tested. If you believe a batch does not match its published Certificate of Analysis, email support@supplypeptides.co.uk with the batch ID and your observations. We will investigate against the retained COA record.
How refunds are issued
Approved refunds are returned via the original bank-transfer route where applicable. Processing times depend on your bank.
