Delivery area and methods
We currently deliver only within the United Kingdom using Royal Mail. Available Royal Mail services, prices and estimated delivery times are displayed at checkout. The particular services offered may depend on parcel characteristics, destination and operational availability.
Orders are dispatched from UK stock after acceptance and cleared payment. Delivery estimates begin at dispatch. We will notify you of material delays. Unless another period is agreed, consumer orders will be delivered within 30 days after the contract is made.
Where tracking is included, we may provide Royal Mail with the recipient's name, delivery address, email address and telephone number as needed for delivery updates, tracking, returns and claims.
Customers must provide a complete, accurate and safe delivery address. Any special storage requirements shown on the product page or label should be followed promptly after delivery.
Consumer cancellation
Consumers may normally cancel an online order from contract formation until 14 days after the day the goods are received. Email info@extolx.co.uk with the order number and a clear cancellation statement, or use the model form in the Consumer Terms.
Return cancelled goods within 14 days after notifying us. Contact us before dispatch so we can provide safe return instructions. Unless goods are faulty, incorrect or misdescribed, the consumer normally pays the direct return cost.
Return address: ExtolX Limited, 44 Hillcrest Avenue, Ingol, Preston, England, PR2 3UP.
We do not impose a blanket exclusion for opened peptide products. If a statutory cancellation exception applies to a particular sealed or rapidly deteriorating product, that exception and the circumstances in which cancellation rights are lost will be stated clearly on its product page before purchase.
Refunds
For a valid cancellation, we refund the product price and the cost of our least expensive standard outbound delivery option. Additional cost chosen for premium delivery is not refundable unless required by law. We may wait until the goods arrive or evidence of return is supplied, where permitted.
Refunds are made within the statutory deadline, normally through the original payment method. Bank-transfer refunds require verified account details and will never require online-banking passwords.
Damaged, incorrect, faulty or unsafe goods
Contact info@extolx.co.uk promptly with the order number, batch number, photographs where safe, and a description. Do not use or dispose of a product suspected to be unsafe unless we or an authority instruct you to do so. Isolate it safely and retain its packaging.
Consumers retain all statutory remedies. Business customers should also follow the inspection provisions in the Business Terms.
Business returns
Business customers have no automatic change-of-mind cancellation right. Prior written return authorisation is required. We may refuse returns that cannot be transported, handled or verified safely, without affecting remedies for non-conforming goods.
