Refund policy

Last updated: 9 July 2026

Our 100-day money-back guarantee. Every Mentex order is covered by a 100-day money-back guarantee. If a formula is not right for you, contact us within 100 days of delivery and we will refund it in full, even if you have opened and used the bottle. The guarantee covers one opened bottle per product, per customer; any further bottles from your order are refunded in full provided they are unused, unopened and in their original sealed packaging. The guarantee is intended for genuine trial of the products, and we reserve the right to decline claims that abuse it.

How to claim. Email support@peptida.co.uk within 100 days of receiving your order with your order number and a few words on why it did not work for you (this helps us improve). We will reply with simple instructions. We may ask you to post the products back to us, including opened bottles; return postage for change-of-mind refunds is your responsibility. Where an item is faulty, damaged or incorrect, we cover the return costs.

Refunds. Once your refund is approved, it will be issued to your original payment method within 5 to 10 business days.

Faulty, damaged or incorrect items. If your order arrives faulty, damaged or incorrect, email support@peptida.co.uk within 48 hours of delivery with your order number and photos of the item and packaging. We will send a replacement or issue a refund, and we will cover any return costs.

Cancellations. If you wish to cancel an order, contact us as soon as possible. If it has already been dispatched, the guarantee process above applies.

Your statutory rights. Nothing in this policy affects your statutory rights under UK consumer law.

Frequently asked questions.

Nootropics are ingredients that are intended to support how your brain works, including functions such as focus, memory, learning, and mental energy. They can include vitamins, plant extracts, amino acids, and other dietary ingredients that are used to support normal cognitive function alongside a healthy lifestyle.

Mentex is a UK supplement brand built on full disclosure: precisely dosed, fully labelled formulas with no proprietary blends. There are two today: Support, a focused nootropic, and Quantum, a comprehensive daily multivitamin.

Choose Support for focus, recall and mental stamina. Choose Quantum for complete daily nutrition, a full vitamin and chelated-mineral base plus advanced nutrients. Many people take both.

Take your daily serving with food or healthy fats for absorption, ideally in the morning. See each product page for its exact serving size.

Some people notice changes in focus and mental energy within the first few weeks. The deeper benefits for memory, clarity, and long-term brain health build gradually over 30 to 90 days of consistent use.

Do not use if you are under 18, pregnant, or breastfeeding, or if you have a medical condition, without speaking to your doctor or pharmacist first. If you take prescription medication, consult a healthcare professional before use.

Yes. Both formulas are vegan: they use plant-based (HPMC) capsules and contain no ingredients of animal origin. Quantum is made on equipment that also handles milk, so its label carries a may-contain notice for anyone with a severe milk allergy.

Usually yes, alongside a balanced diet, but avoid duplicating high doses of the same vitamins and follow total daily intake guidance. If you are unsure, speak to a healthcare professional or pharmacist.

Yes. We offer free standard shipping on all UK orders.
