Across the five Impact Whey offers we traced from 2022 to 2025, advertised discounts ranged from 17% to 61%, averaging 49%. The sale price per kilo ranged from £15.78 to £26.59.

Myprotein's sales tend to cover both of its best-known shakes: Impact Whey, the milky everyday shake, and Clear Whey, a light, juice-style drink. A bigger discount on one can easily tempt you into the other.

Myprotein's clear whey offers have ranged from 41% to 64% off, but listings have not always given the pack size, which makes them hard to price per kilo. If clear whey is what you actually drink, check the weight on the product page before comparing. If you have never tried it, our clear whey explainer is a cheaper place to start than a big discounted tub.

Whey is only part of the sale. Since 2022, Myprotein's Black Friday has also cut vegan protein, clear whey, gainer, bars, cookies and creatine, with advertised discounts from 21% to 64%, averaging 45%. The creatine guide compares the creatine tubs.

Some offers are stunts rather than prices, such as 1kg of Impact Whey for £1 to the first 1,000 app users in 2024, reported by Stack3d. Fun if you catch it, but not a price to plan around.

The Black Friday price is not always the lowest you can pay. Before checking out, run through these five.

1. 1

   Voucher codes. Myprotein often runs more than one code at a time, and the best one depends on your basket. Try each code you find and keep the one that gives the lowest total, with delivery, for your flavour and size.

2. 2

   Discounts for who you are. Student Beans lists extra student discounts at Myprotein, and Blue Light Card lists an extra 10% for verified members. Exclusions apply, so check whether a code works alongside the sale price before relying on it.

3. 3

   A different retailer. The same tub sometimes costs less on Amazon or eBay than on Myprotein's own site, especially for a single bag where delivery adds up. Our Myprotein comparison and product pages show those listings where we track them.

4. 4

   Clearance and short-dated stock. Clearance and short-dated protein can undercut a Black Friday code. Our sales page tracks clearance deals; check the best-before date before you buy.

5. 5

   Subscriptions. Compare Myprotein's subscription price with the best one-off code for your flavour and size. Its Cyber subscription terms require three deliveries before you can cancel, so judge the cost of all three, not just the first bag. Choose a delivery interval that matches how quickly you finish it.

Myprotein's past Impact Whey discounts averaged 49%. Repeated this year, that would take a 1kg bag from today's £34.49 to about £17.59.

Treat that as a yardstick, not a forecast. Today's price is from our Myprotein comparison on 4 October 2026, and past discounts were measured from Myprotein's own 'was' prices, which have sat above its everyday price. The chart runs the same sum for the 2.5kg bag.

Black Friday is 27 November 2026, with Cyber Monday on 30 November. This year's offers have not been announced. If your current bag will last until then, waiting costs nothing. If it will not, a small bag now at a fair price beats a large one at full price.
