Black Friday 2026: What Protein and Supplement Deals to Expect

Quick answer

Expect offers on whey, vegan protein, clear whey, creatine and snack boxes from Myprotein, Bulk and The Protein Works. In past years they started days before Black Friday and some got cheaper by Cyber Monday, which fall on 27 and 30 November 2026. Bigger bags were usually, but not always, cheaper per kilo, and the price per kilo told you more than the discount badge.

54%Across 27 offers with a stated discount

We traced 28 past UK Black Friday protein offers with a known pack size, from 2021 to 2025, across Myprotein, Bulk and The Protein Works. Sale prices ranged from £11.77 to £26.59 per kilo, and advertised discounts from 15% to 69%, averaging 54%.

The clearest pattern is size. Within a single sale, bigger bags were usually cheaper per kilo.

Two caveats keep this honest. These are prices per kilo of powder before delivery, and protein per 100g varies between powders, especially between plant blends and whey, so check the label. The offers also span different years and flavours: this ranks past deals, it does not forecast this year's.

Sale price divided by pack weight, before delivery. Dot size shows pack weight, from 500g to 5kg. The full list of 28 is in the table view. Different years, flavours and channels; not a forecast for 2026.

Black Friday is a week, not a day

The name suggests a single Friday. The record suggests otherwise: in the years we traced, offers were reported from eight days before Black Friday to the Monday after, and some prices fell further by Cyber Monday.

This year Black Friday falls on 27 November, with Cyber Monday on 30 November. If the pattern holds, the useful window opens the week before and closes on the Monday after. Some extra codes have lasted only a couple of days, which is much easier to handle when you already know the one product you are waiting for.

Past offers, mapped onto Black Friday week 2026

Each numbered marker sits where a past offer was reported, counted from that year's Black Friday. Offers may have started before they were reported. Shaded days span the earliest and latest reports.

What each category has looked like on sale

Not every product behaves the same way in a sale. Here is what past UK coverage shows for each category, and the one detail that decides whether an offer is worth having. For creatine, the creatine guide goes further, including why gummies deserve extra suspicion.

CategoryWhat past sales looked likeThe detail that decides it
WheyBulk Pure Whey 1kg from £12.99 (2021) to £16.65 (2023); 5kg sacks from £63.49 (2021) to £79.99 (2024); Myprotein Impact Whey 1kg from £15.78 to £26.59Price per kilo. Bigger bags were usually, not always, cheaper
Vegan proteinThe Protein Works Vegan Protein, 500g at £7.39 up to 4kg at £47.09 (2025); Myprotein Vegan Blend 1kg at £15.00 (2022)Protein per 100g on the label, since recipes vary
Clear wheyMyprotein Clear Whey 500g at £12.62 and Protein Works Clear Diet Whey 500g at £17.49 (both 2023)Pack size, which some later listings left out
CreatineMyprotein Impact Creatine 1kg at £19.50 with a code (2025); Bulk creatine 1kg at £27.89 (2024); Myprotein THE Creatine 250g at £14.99 (2025)Creatine per serving, especially in gummies and blends
Bars and cookies12 Myprotein Impact bars at £13.88 (2022); nine Protein Works vegan bars at £10.99 (2024); 12 Myprotein cookies at £14.49 (2025)Whether you already buy them
04

Snack boxes: only a deal if you eat them

Snack boxes have come in at £1.16 to £1.22 a piece across the three we traced, so taste should settle this one, not price. The more useful question is whether a box of nine or twelve will actually get eaten. A multipack bought because it was discounted, then forgotten in a drawer, is the most expensive snack in the house.

What 2026 could look like

Past Black Friday discounts averaged around half off at all three retailers. Repeated this year, that would take a 1kg bag of Myprotein Impact Whey from today's £34.49 to about £17.59; the chart applies each retailer's own average to one bestseller.

These are illustrations, not forecasts: 2026 offers have not been announced, and past discounts were measured from 'was' prices that often sat above the everyday price. Bulk's figure starts from a July price that was already on sale, so it is the optimistic end.

Three bestsellers in 2026, if past discounts repeat

Grey is the latest catalogue price (4 October 2026; Bulk 19 July 2026, already a sale price); green applies that retailer's average past Black Friday discount. Before delivery.

Latest catalogue priceAt the average past discount
Myprotein Impact Whey · 1kg£34.49£17.59

£13.45 to £28.63 across past discounts

The Protein Works Whey Protein 80 · 1kg£31.99£14.40

£10.56 to £17.59 across past discounts

Bulk Pure Whey · 5kg£129.99£57.20

£49.40 to £67.59 across past discounts · past Black Friday prices £63.49 to £79.99

Illustration, not a forecast: 2026 offers have not been announced. Past discounts were measured from each retailer's stated was price, which has often sat above the everyday price, so a repeat may save less against today's price.

06

Five ways to pay less than the sale price

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

  1. 1

    Voucher codes. Retailers often run more than one code during the sale. Try each one you find and keep whichever gives the lowest basket total with delivery.

  2. 2

    Discounts for who you are. Myprotein, Bulk and The Protein Works all list extra discounts for students and Blue Light Card members, typically 5% to 20% off. Some stack with sale prices and some do not; the Myprotein, Bulk and Protein Works guides have the details.

  3. 3

    A different retailer. The same product can cost less on Amazon or eBay than on the brand's own site. Our protein comparison and product pages show those listings where we track them.

  4. 4

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

  5. 5

    Subscriptions. A lower subscription price is worth checking alongside a one-off code. Compare the delivered total for the same pack, then look at what repeat orders cost. Set the interval to match how quickly you finish it; another pack arriving while the first is still half full ties up money instead of saving it.

07

Your ten-minute plan for November

You do not need to watch every sale. You need one number: what your usual order costs today. With that written down, every offer in November becomes a simple yes or no.

For retailer detail, the Myprotein guide covers whey, clear protein and cookies, The Protein Works guide explains its unusually deep discount badges, and the Bulk guide works through the 5kg sack and basket thresholds. To see how far badges can mislead, read whether Black Friday deals are really cheaper. If you will run out before November, compare what is available now rather than paying full price for a stopgap.

Three steps before 27 November

01

Note your price to beat

October

Today's checkout total for your usual product, flavour and size, delivery included.

02

Pick one retailer to watch

Mid November

Use the retailer guides to see what each has discounted before.

03

Rebuild the same basket

From 19 November

Buy if the final total, with code and delivery, beats your note.
