Everything you might want to ask.

PeptideSupermarket® is the UK's most comprehensive peptide price comparison service, operated by PeptideSupermarket®. We aggregate pricing data from over 90 UK-based peptide suppliers so researchers can instantly compare costs, find the best deal, and make informed purchasing decisions - all from a single website.

No. We do not sell, supply, manufacture, store, or ship any products. PeptideSupermarket® is strictly a price comparison and information service. When you click "View Deal" or any outbound link, you are redirected to the supplier's own website. Any purchase you make is a transaction solely between you and that third-party supplier.

PeptideSupermarket® is operated by PeptideSupermarket®, a company registered in Estonia. We are an independent price comparison service with no ownership stake in any peptide supplier.

We update prices regularly by automatically checking supplier websites. However, suppliers can change their prices at any time without notice. We recommend always verifying the final price on the supplier's website before making a purchase, as the price displayed on our site may not reflect real-time changes.

We aim to list every UK-based peptide supplier we can identify, regardless of whether we have an affiliate relationship with them. Listing a supplier on our site does not constitute an endorsement, recommendation, or guarantee of that supplier or their products. We do not verify supplier credentials, product purity, or regulatory compliance.

We make every effort to display accurate, up-to-date pricing. However, prices are sourced from third-party supplier websites and can change at any time. We make no guarantee that prices shown are current or complete. Always confirm the final price directly with the supplier before purchasing.

Some pages on our site highlight a supplier or product in a "Featured" position at the top of the listing. This is purely a listing placement - it does not mean we have vetted, tested, verified, or endorsed that supplier or their products in any way. We do not check product quality, purity, authenticity, or supplier credentials. Featured placements may be influenced by affiliate relationships, pricing data, or other factors. As with all listings on our site, the decision to purchase from any supplier is entirely yours, and you should conduct your own due diligence before buying.

We participate in affiliate marketing programmes with some UK peptide suppliers. When you click through to a supplier's website via our links and make a qualifying purchase, we may receive a commission from that supplier. This is the primary way we fund our operations. For full details, please read our Affiliate Disclosure page.

No. The commission we earn is paid by the supplier, not by you. Our affiliate relationships do not increase the price you pay. In many cases, we also display available coupon codes that can save you money.

We are committed to impartial comparisons. All suppliers are listed regardless of whether we have an affiliate relationship with them. Default sorting is by price, not by commission rates. Any supplier ratings are based on genuine, transparent criteria - not affiliate status. Featured supplier or product placements at the top of pages may be influenced by affiliate relationships, but this is always a listing only - it does not constitute an endorsement, recommendation, or guarantee. We do not verify supplier credentials, product purity, or regulatory compliance.

No. We list suppliers regardless of whether we have an affiliate relationship. Some suppliers on our site generate no revenue for us at all. Our goal is to provide the most complete comparison possible, not to promote only paying partners.

Our complete Affiliate Disclosure is available at peptidesupermarket.co.uk/disclosure. It covers how we make money, our commitment to impartiality, limitation of liability, and our no-endorsement policy. We encourage all users to read it.

Some suppliers provide us with coupon codes that we display alongside their listings. These codes are applied on the supplier's own website at checkout. We make every effort to keep coupon codes current, but we cannot guarantee that any code will be accepted - suppliers may change or expire codes at any time without notifying us.

Yes. If you know of a UK peptide supplier that isn't listed on our site, we'd love to hear about it. Please contact us at hello@peptidesupermarket.co.uk with the supplier's details and we'll review them for inclusion.

We strive for accuracy but rely on data sourced from third-party supplier websites. If you spot an error - whether it's a price, product detail, or supplier information - please let us know via the "Request Changes" button on the relevant page or email us at hello@peptidesupermarket.co.uk. We'll investigate and update the listing promptly.

We collect standard analytics data to understand how our site is used and to improve the service. We do not require registration and do not store any personal purchasing information. When you click through to a supplier, you leave our site entirely - any data you provide to a supplier is governed by their own privacy policy.

No. We do not share any personal data with suppliers. When you click an affiliate link, the supplier may use cookies to track the referral, but we do not pass any identifying information about you to any third party.
