Myprotein Discount Code September 2026

Current Myprotein discount codes & offers (September 2026)

How a Myprotein discount code works

At Myprotein, almost every product page shows a 'was' price and a saving, and on top of that the site often runs a basket-wide extra percentage off. At the time of writing, most items carried a banner for an extra 10% off with no minimum spend, applied automatically in the basket. The terms describe several promotion types that come and go: site-wide or selected-item discounts, tiered offers that grow with your spend, discounts that shrink over time, multi-buys where the cheapest item is reduced, free gifts added to the basket and free-delivery offers.

There is a discount-code box in the basket, and the terms are strict about how it works: only one code per basket, a maximum discount of £500 per order unless a promotion says otherwise, and gift vouchers plus the Vitality range excluded. Whether a code stacks with a product's reduced 'was/now' price depends on the promotion. A gift voucher also goes in the code box and cannot be combined with another code, so you have to choose one or the other.

Myprotein runs several of its own schemes. Signing up to emails currently gives an extra 15% off a first order. The app has app-only discounts, early access to flash sales and a first-app-order deal. Refer-a-friend gives the new customer £15 off and the referrer £15 credit once the friend spends £45, although the referral code cannot be combined with another code on that first order. There are also student and graduate discounts, and key-worker discounts verified through a third-party service.

Subscriptions are a separate route to a lower price. Many products can be put on repeat delivery with free delivery on recurring orders, and you can skip, change or cancel through your account. Watch the fine print on limited-time subscription deals: those fix the discounted price for three deliveries, but you have to accept all three, so a three-monthly plan ties you in for nine months. The rhythm is constant rather than seasonal: prices and basket offers change week to week, so an offer you missed is rarely gone for long.

About Myprotein

Myprotein began in 2004 as a small online protein business and joined THG, the Manchester e-commerce group, in 2011. The brand's own history page says that by 2016 it was the world's leading online sports-nutrition brand, and the homepage now calls it the No.1 online sports-nutrition brand, citing Euromonitor retail figures for 2025. Over the years it has grown into a family of ranges: Myprotein for the core powders, MP for activewear, Myvitamins for supplements and Myvegan for plant-based products. The company still describes Manchester as home, and the UK storefront is its original market rather than a translated add-on.

What sets Myprotein apart from most supplement shops is that it is mainly a manufacturer, not a reseller. Its quality page says it runs six of its own production and development sites in the UK, Poland and the USA, and that the flagship Warrington facility holds a BRCGS AA grade, the top rating in that food-safety scheme. The site describes testing both before production and before dispatch, including near-infrared checks on ingredients and X-ray screening for foreign objects. Certain products carry Informed Choice, Informed Sport or Informed Protein certification, and certified batches can be checked on the testing body's own website.

The range is enormous. Protein alone is split by type (whey, clear whey, isolate, casein, hydrolysed, vegan, collagen), by goal and by three tiers called Impact, Origin and PRO. Around it sit creatine, pre-workout, electrolytes, amino acids, vitamins, gummies, protein bars, cookies, spreads, sauces, cereal and shakers. There is even a GLP-1 support section and a fibre range. The flagship Impact Whey Protein comes in more than 40 flavours and in sizes from a small pouch to a 150-serving bag, and the product page shows the price per serving for each size, which is the number worth comparing.

Collaborations are a big part of the identity. Impact Whey is sold in Snickers, Mars, Bounty and Twix flavours, clear whey comes in a Vimto version, and there have been tie-ups with Hotel Chocolat and a Jelly Belly range that won a licensing award in 2023. Alongside nutrition, the MP clothing line covers gym wear, seamless sets and accessories such as lifting straps and running vests. The site also lists products from other brands, and some of those are sold and shipped by marketplace partners rather than by Myprotein itself, which the product page states.

For a UK buyer, the seller is THG Nutrition Limited, registered at Icon 1, 7-9 Sunbank Lane, Ringway, Altrincham. If you pay with Frasers Plus credit, the contract is with The Hut.com Limited instead. The terms are governed by the law of England and Wales, give a 14-day cancellation right from the day you receive the goods, and state that UK deliveries carry no extra taxes. Payment options include the main cards, PayPal, Apple Pay, Klarna and Frasers Plus. Customer service runs through messages in your account and live chat.

Reputation is solid for a shop of this size. On Trustpilot's UK site Myprotein holds a 4.3 average across more than 223,000 reviews. Recent reviewers mainly praise the flavours, value and quick delivery. The complaints are about rising prices, missing items or damaged packaging now and then, and courier experiences, including late-evening doorstep deliveries. Myprotein does not appear to use Feefo, so Trustpilot is the main independent source. Product ratings on the site itself are collected and moderated by Myprotein, and its policy requires incentivised reviews to start with the word 'Advert'.

Why shop at Myprotein?

• Made in its own factories — Most of the range is produced in Myprotein's own facilities in the UK, Poland and the USA rather than bought in. The Warrington plant holds a BRCGS AA grade, and the site describes ingredient checks before production and product testing before dispatch. For a powder you drink every day, knowing who actually made it counts for more than a slick label.
• Independently tested lines — Impact Whey Protein carries both Informed Choice and Informed Protein certification: one screens for banned substances, the other verifies that the protein content on the label is accurate. Separate filters on the site show Informed Sport products too, which matters for anyone competing in a drug-tested sport. Certified batches can be looked up on the testing programme's own website.
• Price per serving on every size — The product page lists every pack size with its cost per serving. At the time of writing, a 30-serving bag of Impact Whey worked out at about £1.10 a serving, while the largest bags came in under £1. That makes it easy to see when a bigger bag is really cheaper and when a sale on a smaller size is the better buy.
• Fast and flexible UK delivery — Standard delivery takes two to three working days and costs £4.49, or nothing over £55. Next-day delivery costs £5.99, is free over £65, and covers orders placed before 1am. There are over 8,500 click-and-collect points, an eco option that finishes the last mile on foot, by bike or by electric vehicle, and same-day delivery in parts of the West Midlands.
• Flavours you won't find elsewhere — Collaborations with Snickers, Mars, Bounty, Twix and Vimto mean you can get chocolate-bar and fizzy-drink flavours in whey and clear whey. If plain vanilla is getting boring, this is one of the few places to get branded flavours as proteins. On-site ratings vary a lot between the collab flavours, so read the reviews for the flavour you want.
• Nutrition, vitamins and gym wear in one basket — Protein, creatine, vitamins, snacks, shakers and MP activewear all count towards the same free-delivery threshold. If you would otherwise order supplements from one shop and gym clothes from another, combining them here clears the £55 threshold more easily and means one delivery instead of two.
• A huge public review base — With more than 223,000 Trustpilot reviews and a 4.3 average, Myprotein's track record is about as well documented as a UK online retailer's gets. Common complaints about pricing and courier hiccups are visible too, so you know what to expect before you order rather than finding out afterwards.

More money-saving tips for Myprotein

• Compare the price per serving, not the 'was' price — Because nearly everything is permanently reduced, the struck-through price tells you little. The product page lists the cost per serving for every size. Use that figure to compare sizes and flavours, and to check whether today's offer is actually better than what you paid last time.
• Check whether the basket offer is already running — When a basket-wide extra percentage is live, it applies automatically, and adding a code usually replaces it rather than adding to it. Put your items in the basket first, look at the total, then try any code and see which result is lower. Only one code works per basket.
• Aim for the £55 threshold — Standard delivery costs £4.49 below £55. If you are close, a shaker, a bar box or a creatine top-up is often cheaper than the delivery charge. Next-day delivery is free only from £65, so decide whether speed is worth the extra spend.
• Think about MyDemand if you order often — MyDemand costs £8.99 a year and gives unlimited standard UK delivery on orders over £10. Two paid standard deliveries cost about the same, so it pays from the third order. It renews automatically unless you cancel, and products from other brands are excluded, so switch it off if you only order once or twice a year.
• Don't open anything you might return — Returns are accepted within 30 days, but powders, bars and other non-clothing products must be unopened with their seals intact, and clothing must be unworn with the tags on. Myprotein doesn't do exchanges, so a wrong flavour means a new order and a refund. If an item is damaged, faulty or wrong, contact customer service through your account instead of using the standard return route.
• Use the price-beat promise before you order — Myprotein will beat a lower price at another UK retailer for the same product, size and flavour, but only if you ask before ordering. The difference comes back as account credit valid for seven days, not as cash, and it doesn't combine with other codes. It suits one big item better than a mixed basket.
• Check who is shipping the item — Some products on the site are sold and shipped by marketplace partners. The product page says so, and delivery times, costs and returns can then differ from Myprotein's own. These items are also excluded from MyDemand, so check the listing before you count on free delivery.
