Quick answer
The useful Q2 conclusion is not that protein became universally cheaper or dearer—it is that brand averages split sharply. Mainstream concentrate promotions improved while several isolates and smaller labels moved the other way. Buyers who stocked up because of a general ‘prices are rising’ headline often missed better later offers. Our response is to stop predicting the whole market and compare the product you need when you need it. Use the figures below as a historical Q1-to-Q2 snapshot, then use the live table for today's decision; April prices should not be presented as a current July quote.
The Q2 headline: most brands dropped, not rose
Across whey concentrate specifically, the UK's most popular category, eleven of the fourteen mainstream brands with enough data dropped their average price per 100g in Q2. Only three rose. The headline movers are not subtle, with double-digit percentage swings inside a three-week window.
This runs opposite to what most protein buyers expect heading into spring. The "prices only go up" narrative has been wrong for Q2 so far, and buyers who stocked up in January on the assumption prices would climb have, in several cases, paid more than anyone needs to today.

Biggest fallers in Q2 2026
The biggest Q2 price drops logged across whey concentrate, the category with the richest data, look like this.

Biggest fallers in Q2 2026 continued
Isolates have moved too, with whey isolate from Yummy Sports down 10.4%, Optimum Nutrition isolate down 3.1%, and Reflex isolate down 3.3%. Mass gainers have stayed steadier, with DY Nutrition the biggest mover at down 8.0%.
The two big takeaways: premium brands (Grenade, Ghost, Cellucor, PhD, Optimum Nutrition) have cut hardest, and MyProtein, the brand most people associate with permanent discounting, has genuinely moved its everyday price per 100g down by double digits, not just its headline sale price.
Community perspective
What others are saying
If you have Costco membership, they have good prices on ON whey and Ascent whey. Another option that I have been using, go on Amazon and find well known brands like Dymatize, BSN Syntha, ON… See if they have save and subscribe discount, it can be up to 40% off. As soon at shipped you can cancel subscription.
u/MaxYeti88 in r/Myprotein
Fuck Myprotein! Did anyone find any good US alternatives for unflavored? ON doesn’t produce unflavored apparently. Feels like if whey prices are at 2015 levels someone should definitely replicate what MP did and sell whey at the prices they used to.
u/eodigah in r/Myprotein
That’s honestly a decent deal. For reference, it’s about $14.55/lb for me in EU. That’s about 40% more expensive. Meanwhile I can buy better whey at $8.88/lb (€16/kg) locally. You should always pick what’s best for your own wallet. I don’t want people to boycott MP - I want them to be able to buy supplements at an affordable price.

How To Pick The Best Protein Powder (CHOOSE WISELY!)

Pros
- 55.5% cheaper per 25g protein than the median of 65 other Whey Protein product families in this comparison
Biggest risers in Q2 2026 continued
The MyProtein split stands out: Impact Whey concentrate came down 11.5%, but Impact Whey Isolate went up 12.5%. Isolate demand has clearly firmed faster than concentrate demand, which lines up with what we are seeing in our GLP-1 protein guide, where isolate is the category pulled upward by weight-loss drug users looking for high protein density per calorie.
Cheapest bags on ProteinDeals right now
Based on the last 14 days of tracked prices, these are the cheapest in-stock whey bags in our live data. Live prices update weekly, and the figures below reflect typical sale pricing over the last fortnight.
- 1
Warrior Whey Protein: floor of £1.70/100g during sales, with 500g bags from £12.00 and 71.2g protein per 100g.
- 2
MyProtein Impact Whey Protein: floor of £2.42/100g, 5kg bags available for serious bulk buyers, 72g protein per 100g across 48 flavours.
- 3
Protein Works Whey 80 BLACK: floor of £2.61/100g, 74g protein per 100g (higher than either Warrior or MyProtein), 1kg bags from around £17.89.
- 4
Bulk Pure Whey Protein: roughly flat quarter on quarter (up 1.5%), with consistent pricing around £2.62/100g and an honest RRP with no inflated headlines.
What is driving the Q2 moves
Three things explain most of the Q2 downward pressure.
- 1
Post-January deflation: Q1 prices were elevated by New Year demand (resolution shoppers, bulking season). Q2 is historically softer, and the decline seen in 2026 runs sharper than usual.
- 2
Brand repositioning: Optimum Nutrition, Grenade, and PhD have all moved their everyday price closer to where their promotional price used to sit, a likely response to pressure from direct-to-consumer budget brands like Bulk, Warrior, and TPW capturing market share on price per 25g protein.
- 3
Isolate splitting from concentrate: demand for high protein density isolates has firmed (driven by GLP-1 users and anyone on a cutting phase) while concentrate demand has softened, pulling isolate prices up and concentrate prices down even within the same brand family.
How to buy in Q2
Three practical implications follow from this data.
- 1
If you are buying whey concentrate, do not wait. Q2 pricing on concentrate runs softer than Q1 across nine of the ten biggest UK brands, and there is no structural reason to delay a buy expecting better prices later.
- 2
If you are buying whey isolate, compare harder. Brand-by-brand moves are split: Bulk Pure Whey Isolate sits flat at roughly £3.62/100g, Optimum Nutrition Isolate is down about 3%, but MyProtein Impact Whey Isolate is up 12.5% versus Q1. Do not assume the brand that was cheapest in January still is.
- 3
Let the tool do the maths. Use the live comparison table sorted by cost per 25g of protein. It updates weekly and normalises for bag size, serving size, and protein density automatically.
How to buy in Q2 continued
Our buying decision: do not stockpile merely because a market article predicts another rise. Keep enough powder to avoid an emergency purchase, then buy when your preferred category reaches a competitive live cost per 25g protein. Compare current protein prices rather than treating this historical index as a price list.
This index remains useful for direction and volatility. The live comparison remains the source for an actual purchase.
