Is Warrior Protein Expensive? What Warrior Whey Costs Per 25g of Protein
Warrior Whey costs £1.16 per 25g of protein in its cheapest in-stock bag, checked 3 October 2026, and its cheap 1kg and 2kg sizes are sold out. What Warrior costs per scoop, how it compares with Myprotein, Bulk and Optimum Nutrition, and the cheaper Warrior protein most people miss.
Kevin, founder of WheyWise
Quick answer
Warrior Whey is no longer the budget whey it used to be. WheyWise price checks on 3 October 2026 put the cheapest in-stock bag, the 1kg on Amazon at £33.15, at £1.16 per 25g of protein: level with Myprotein Impact Whey's 1kg at £1.15, and 21.5% dearer than Impact Whey's 2.5kg bag at 96p. Warrior's own cheap sizes, the 1kg at £29.99 and the 2kg at £49.99, were both sold out on teamwarrior.com, and the brand's Serious Protein page says it “retired” whey rather than pass rising whey costs on. The one to buy is Warrior Serious Protein, a soy and milk protein blend with 24g of protein per 30g scoop at £12.50 for 500g, which is 78p per 25g of protein and cheaper than every whey in this comparison. If it has to be whey, Bulk Pure Whey at 93p per 25g of protein in the 2.5kg bag is the better buy than Warrior's.
Is Warrior protein expensive?
Warrior Whey is mid-priced, not cheap. Checked 3 October 2026, the cheapest in-stock Warrior Whey we track is the 1kg bag on Amazon at £33.15, which is £1.16 per 25g of protein, level with Myprotein Impact Whey at the same size and 21.5% dearer than Impact Whey in its 2.5kg bag. The 500g bag direct from Warrior is £17.99, or £1.26 per 25g of protein.
On paper Warrior is still cheap: the 2kg bag lists at £49.99 on teamwarrior.com, which would be 88p per 25g of protein and cheaper than any big-brand whey in this post. The problem is that it, and the £29.99 1kg bag, were sold out in every flavour on 3 October 2026. The price you can actually pay today is the Amazon one.
Has Warrior stopped selling whey?
Not entirely, but it says it has stepped back from it. Warrior's Serious Protein page, read on 3 October 2026, says whey prices “have risen massively over the past couple of years” and that “rather than sell whey at a loss, or pass that cost on to you, we retired it”, launching Serious Protein in its place at “78p a shake in the 500g”. On the same day the 500g Warrior Whey was still on sale in nine flavours, while every flavour of the 1kg and 2kg was sold out.
That matters for the price question. If the big bags do not come back at £29.99 and £49.99, Warrior Whey's real price is what Amazon and the 500g bag charge, which puts it in the middle of the market. Our explainer on why whey protein prices are rising covers the cost pressure Warrior is describing.

How much protein is in a scoop of Warrior Whey?
A 25g scoop of Warrior Whey gives 17.8g of protein and 97 kcal in White Chocolate and Vanilla Ice Cream, according to the label on teamwarrior.com on 3 October 2026. The “36g protein” on the front of the bag is a 50g double scoop, twice the serving most brands use, so it is not comparable to a rival's 22g or 24g without adjusting for that.
| Product (flavour) | Scoop | Protein per scoop | kcal per scoop | Sugar per scoop | Protein per 100g |
|---|---|---|---|---|---|
| Warrior Whey (White Chocolate, Vanilla Ice Cream) | 25g | 17.8g | 97 | 3.05g | 71.2g |
| Warrior Whey (Double Chocolate) | 25g | 17.5g | 95 | 2.1g | 70g |
| Serious Protein (Chocolate Milkshake) | 30g | 24g | 107 | 1.4g | 79.9g |
| Clear Whey Protein Isolate (Blue Raspberry) | 25g | 22.5g | 94 | 0.10g | 90g |
Labels read on teamwarrior.com, 3 October 2026. Each row names the flavour its figures come from.
Warrior Whey contains 71.2g of protein per 100g, which is normal for a whey concentrate: level with Bulk Pure Whey at 71g and Myprotein Impact Whey at 72g, and below Optimum Nutrition Gold Standard at 76g. The surprise is that Warrior's non-whey product carries more. Serious Protein is 79.9g of protein per 100g, because soy protein isolate is a more concentrated protein than whey concentrate.
What does Warrior cost per scoop and per 25g of protein?
Warrior Whey costs 83p to 90p per 25g scoop on the bags you can buy today, checked 2 and 3 October 2026, and £1.16 to £1.26 per 25g of protein. Because a Warrior scoop holds 17.8g of protein rather than 25g, cost per 25g of protein is the fairer number to compare.
| Product and pack | Price, where | Price per scoop | Cost per 25g protein |
|---|---|---|---|
| Serious Protein 500g | £12.50, Warrior | 75p (30g) | 78p |
| Warrior Whey 1kg | £33.15, Amazon UK | 83p (25g) | £1.16 |
| Warrior Whey 2kg | £66.65, Amazon UK | 83p (25g) | £1.17 |
| Warrior Whey 500g | £17.99, Warrior | 90p (25g) | £1.26 |
| Clear Whey Protein Isolate 375g | £17.24, Amazon UK | £1.15 (25g) | £1.28 |
| Warrior Whey 2kg (sold out) | £49.99, Warrior | 62p (25g) | 88p |
| Warrior Whey 1kg (sold out) | £29.99, Warrior | 75p (25g) | £1.05 |
WheyWise price checks: Amazon Warrior Whey 1kg 3 October 2026, Amazon 2kg and Clear Whey 2 October 2026, Warrior direct prices 2 October 2026 and confirmed on teamwarrior.com, with stock status, on 3 October 2026. Cost per 25g of protein uses each product's own label.
The sold-out rows are the reason Warrior had a budget reputation. At £49.99 for 2kg, Warrior Whey would cost 88p per 25g of protein, cheaper than any big-brand whey we compare here. At the Amazon 2kg price of £66.65 it costs £1.17, a third more for the same bag. Warrior Clear Whey Protein Isolate costs £1.28 per 25g of protein on Amazon and £1.33 direct at £17.99; the clear whey comparison ranks it against the rest.

Is Warrior dearer than Myprotein, Bulk and Optimum Nutrition?
At 1kg, Warrior Whey is level with Myprotein, dearer than Bulk and much cheaper than Optimum Nutrition. Checked 3 October 2026, Warrior Whey 1kg at £1.16 per 25g of protein compares with £1.15 for Myprotein Impact Whey 1kg, £1.06 for Bulk Pure Whey 1kg and £1.55 for Optimum Nutrition Gold Standard 900g. In the biggest bags Warrior falls behind, because its 2kg on Amazon is £1.17 against 96p for Impact Whey and 93p for Bulk Pure Whey.
| Product | Protein per 100g | Around 1kg | Biggest bag |
|---|---|---|---|
| Warrior Serious Protein (not whey) | 79.9g | 78p (£12.50, 500g, Warrior) | 78p (500g only) |
| Bulk Pure Whey | 71g | £1.06 (£29.99, 1kg, Amazon) | 93p (£65.69, 2.5kg, Amazon) |
| Myprotein Impact Whey | 72g | £1.15 (£32.99, 1kg, Myprotein) | 96p (£69.00, 2.5kg, Amazon) |
| Warrior Whey | 71.2g | £1.16 (£33.15, 1kg, Amazon) | £1.17 (£66.65, 2kg, Amazon) |
| Optimum Nutrition Gold Standard 100% Whey | 76g | £1.55 (£42.53, 900g, Amazon) | £1.23 (£170.00, 4.53kg, Amazon) |
Cost per 25g of protein. WheyWise price checks on 2 and 3 October 2026 (Myprotein direct, Warrior direct and Warrior 2kg on Amazon 2 October, the rest 3 October). Protein per 100g from each brand's label: Warrior Whey in White Chocolate, Serious Protein in Chocolate Milkshake, Bulk Pure Whey as listed on bulk.com, Impact Whey in Vanilla, Gold Standard in Double Rich Chocolate.
Warrior Serious Protein at 78p per 25g of protein is 18.4% cheaper than Myprotein Impact Whey's 2.5kg bag and 15.5% cheaper than Bulk Pure Whey's, without needing a big bag at all. That is the real reason to look at Warrior on price. For the head to head most Warrior buyers are weighing up, see Mutant Whey vs Warrior Whey, and the sister posts on why Myprotein is so expensive and whether Bulk is expensive cover the rivals.
Is Warrior Whey good quality for the price?
Warrior Whey is a standard whey concentrate and milk protein blend, and its protein figures add up. The ingredient list on teamwarrior.com, read 3 October 2026, is whey protein concentrate, milk protein, flavouring, xanthan gum, soy lecithin (0.4%) and sucralose, and Warrior publishes a full amino acid profile whose 18 amino acids total 71.2g per 100g, exactly matching the protein on the label.
No sign of amino spiking. Warrior Whey lists no free amino acids such as glycine or taurine, and its leucine works out at 2.65g per 25g of protein, above the roughly 2.5g benchmark in our protein spiking guide. Serious Protein includes “glutamine peptides”, which Warrior says come from wheat protein, so they are a protein ingredient rather than a free amino acid added to inflate the count.
The marketing and the label disagree in places. The 500g product description lists sugar at under 1.5g, while the nutrition table on the same page shows 3.05g per 25g scoop in White Chocolate and Vanilla Ice Cream, which is 12.2g per 100g. The description says soy-free, while the ingredient list includes soy lecithin. And the 1kg page describes a blend including isolate, which the ingredient list does not show. None of this changes the protein you get, but read the table, not the copy.
Testing is not independently certified. Warrior says Warrior Whey is made in the UK in GMP-certified facilities, but its product page names no third-party testing programme, and when we wrote our Warrior Whey review we found no Informed Sport or Informed Choice listing for it. If you are drug tested, the best third-party tested protein powders guide is the place to start.
Serious Protein is not a downgrade for muscle. A meta-analysis of nine resistance-training studies found no difference in strength or lean mass gains between soy protein and whey or other animal proteins (Messina et al., 2018). The trade-offs are allergens and taste, not results: it contains soy, milk and gluten. Our plant protein vs whey comparison goes deeper on soy against whey.
How many flavours does Warrior Whey come in?
Warrior Whey comes in nine flavours in the 500g bag on teamwarrior.com, checked 3 October 2026: Double Chocolate, Strawberry Creme, Vanilla Ice Cream, Vanilla Milkshake, Salted Caramel, Chocolate Brownie, Strawberry Milkshake, White Chocolate and Coconut. The sold-out 1kg also lists Unflavoured, which makes ten across the range. Serious Protein has three (Chocolate, Strawberry and Vanilla Milkshake) and Clear Whey Protein Isolate has four (Blue Raspberry, Sour Apple, Pineapple and Fruit Punch).
On the reviews we fetched from teamwarrior.com, Warrior Whey 1kg averages 4.5 out of 5 from 54 reviews and the 500g bag 4.6 from 49, both read on 3 October 2026. The flavours buyers name most warmly are White Chocolate, which one buyer called their favourite, Salted Caramel, which two buyers praised, and Double Chocolate. The criticism is specific too: one buyer said the Unflavoured “tastes rank”, another would not recommend Vanilla Ice Cream, and one found the powder “very bitty” when mixed. Those are individual reviews on Warrior's own site, not a taste test, so treat them as a pointer.
When is Warrior worth paying for, and when is it not?
Warrior is worth buying for Serious Protein, and for Warrior Whey only when the big bags are in stock. At 78p per 25g of protein, Serious Protein is cheaper than every whey in this post, and at £49.99 for 2kg, Warrior Whey would be 88p. At today's in-stock prices of £1.16 to £1.26 per 25g of protein, Warrior Whey has no price advantage over Myprotein or Bulk.
It is worth it if: you want the cheapest protein per gram from a UK brand and are fine with soy and milk instead of whey, you like Warrior's confectionery flavours, or you can catch the 2kg Warrior Whey back in stock at £49.99.
It is not worth it if: you want whey and are buying today, because Bulk Pure Whey at 93p and Myprotein Impact Whey at 96p per 25g of protein in 2.5kg bags both beat Warrior Whey's £1.17 in the 2kg. And skip Serious Protein if you avoid soy or gluten, or need an independently tested product.
Where is Warrior Whey cheapest in the UK?
Right now, Amazon UK for the 1kg bag and Warrior direct for the 500g. Checked 3 October 2026, the 1kg Warrior Whey was £33.15 on Amazon, £1.16 per 25g of protein, and the 500g was £17.99 on teamwarrior.com, £1.26 per 25g of protein. If the 1kg and 2kg come back in stock on teamwarrior.com at their listed £29.99 and £49.99, buying direct becomes the cheapest option by a distance.
Serious Protein is £12.50 for 500g direct from Warrior, the only retailer we track that sells it. Live prices for the whole range are on the Warrior brand page, the whey concentrate comparison ranks every whey by cost per 25g of protein, and the protein comparison tool puts any two side by side. If you are not sure which type of protein suits you, the protein finder takes about a minute.
Frequently asked questions
Is Warrior Whey expensive?
It is mid-priced now, not cheap. Checked 3 October 2026, the cheapest in-stock Warrior Whey we track is the 1kg bag on Amazon at £33.15, which is £1.16 per 25g of protein. That is level with Myprotein Impact Whey's 1kg at £1.15, 21.5% more than Impact Whey's 2.5kg at 96p, and 5.7% less than Optimum Nutrition Gold Standard's 4.53kg at £1.23. The 500g bag direct from Warrior is £17.99, or £1.26 per 25g of protein.
Why is Warrior Whey out of stock?
Warrior's product pages do not say why the 1kg and 2kg bags are sold out, but its Serious Protein page explains that whey prices have risen sharply and that, rather than sell whey at a loss or pass the cost on, it retired whey and launched Serious Protein in its place. On 3 October 2026 every flavour of the 1kg and 2kg Warrior Whey was sold out on teamwarrior.com, while the 500g bag was still on sale in nine flavours.
How much protein is in a scoop of Warrior Whey?
17.8g of protein in a 25g scoop, according to the label on teamwarrior.com on 3 October 2026, which is 71.2g of protein per 100g in White Chocolate and Vanilla Ice Cream. The 36g protein figure on the front of the bag is for a 50g double scoop, twice the serving most brands use.
Is Warrior Serious Protein as good as whey?
For building muscle, the evidence says soy protein does about as well as whey over a training block. A 2018 meta-analysis of nine studies found no difference in strength or lean mass gains between soy and animal protein supplements during resistance training. Serious Protein is a blend of soy protein isolate, skimmed milk powder, glutamine peptides from wheat and casein, at 24g of protein per 30g scoop. It is not whey, it is not vegan and it is not gluten-free.
Is Warrior Whey third-party tested?
Warrior's product page says it is made in GMP-certified UK facilities but does not name a third-party testing programme. When WheyWise reviewed Warrior Whey we found no listing in the Informed Sport or Informed Choice databases. If you are tested for banned substances, choose a product carrying the Informed Sport mark.
