Per4m have just dropped five brand-new whey protein flavours, and this might be the most creative line-up we've seen from them yet. From chocolate-cake-inspired blends to sweet-and-salty curveballs, these go well beyond your standard whey options.
But here's the twist: these flavours aren't just new — they're competing. One of them will be turned into a full-size tub based on what you lot vote for.
If you're into dessert-style shakes, bolder flavour profiles, or you're just bored of the usual chocolate-vanilla-strawberry trio, these are well worth a look. You can browse the full Per4m range here.
A closer look at the new Per4m flavours
Each one brings something different to the table. Some feel warm and familiar; others are out there for people who like to try something new. Here's the rundown.
Vincent The Caterpillar
Vincent is a rich, chocolatey flavour with a creamy finish that feels far more indulgent than your average chocolate whey. Instead of a plain chocolate shake, you get notes of buttercream, soft vanilla and a deeper cocoa flavour — more cake than milkshake.
It's nostalgic and comforting, but elevated enough to stand out. If chocolate protein is your usual go-to but you fancy something a bit more interesting, this could be a real contender.

French Toast Maple Swirl
This one leans right into sweet, breakfast-inspired territory — rich fried-bread notes, maple syrup sweetness, and hints of cinnamon and caramelised butter. There's a soft custardy quality to it too, which gives it a warm, comforting finish.
It's indulgent and full-bodied, so if you love a sweeter whey, this is right up your street. It's got that proper comfort-food feel that could easily translate into a popular full-size tub.

Cinnamon Crunch
Cinnamon Crunch looks like one of the easiest crowd-pleasers of the lot. Aromatic cinnamon, sweet caramelised sugar and toasted grain notes come together to recreate that moreish cereal-milk flavour we all secretly love.
It's creamy, smooth and made for everyday use. If there's a safe bet to win here, this is right near the top.
Raspberry White Chocolate Matcha
This is easily the most distinctive flavour in the collection. It opens with a sweet white chocolate base, then sharp raspberry cuts through, before matcha rounds it off with an earthy, slightly savoury finish.
It's not a safe or standard whey flavour — which is exactly why it's the wildcard. It could either steal the show or stay a niche favourite, depending entirely on your taste.

Churro Pretzel
Churro Pretzel brings sweet and salty together in a way that grabs your attention straight away. It starts with fried bread and cinnamon, then rolls into buttery sweetness with a subtle salty pretzel twist.
That balance sets it apart from typical whey flavours, and it feels like a strong shout for anyone who wants something a little different without straying too far from familiar dessert territory.
So, which flavour will win?
Here's what makes this drop different: it's not just about trying new flavours — it's about deciding the future of the range.
One of these five will be picked to become a full-size tub, based purely on your feedback and demand. In other words, it's a live vote on what people actually want in their shakes.
Each flavour offers something different:
- Vincent The Caterpillar – rich, nostalgic chocolate dessert
- French Toast Maple Swirl – sweet, comforting breakfast-style
- Cinnamon Crunch – easy, everyday cereal milk
- Raspberry White Chocolate Matcha – bold and experimental
- Churro Pretzel – sweet-and-salty standout
Some will naturally pull in a wider crowd, while others stand out for being unique. The fun part is seeing which way it goes — a safe everyday flavour, or something more adventurous.
More than just flavour
The flavours are the headline, but every option still delivers where it counts. Each sachet packs around 20 to 21 grams of high-quality whey protein with a complete amino acid profile to support recovery and performance.
So you're not trading performance for taste — these are still proper functional protein products, just with a more creative spin on flavour.
