We've been keeping something under lock and key, and it's finally time to let you in on it.
Meet Black Friday Gateau, our exclusive new protein flavour for Black Friday 2026. Inspired by a rich Black Forest gateau, it brings together indulgent chocolate, sweet cherry notes and a creamy finish. It's available in both Per4m Advanced Protein Blend and Whey, complete with the first black protein tubs we've ever released.
We've gone all in on this one. Black Friday Gateau is a one-time-only release, and once the limited stock has sold out, the flavour won't be coming back. Ever.
Meet Black Friday Gateau
Think layers of rich chocolate sponge, sweet cherries and smooth cream. The sort of dessert you'd usually find yourself going back for another slice of, except this time we've turned the flavour into your daily protein shake.
The packaging has had the Black Friday treatment too. For the first time in Per4m history, we've swapped our signature white protein tubs for an exclusive black design, finished with deep red detailing and Black Friday Gateau artwork.
We reckon the black tubs look pretty good. The flavour inside has a lot to live up to.
Available in Advanced Protein Blend and Whey
Black Friday Gateau is available in two Per4m protein ranges, so you can get your hands on the limited-edition flavour in whichever format you prefer.
Advanced Protein Blend
Whey
Black Friday Gateau Advanced Protein Blend combines five protein sources in one smooth, easy-mixing blend. The featured 1800g format delivers 20g of protein per serving, with all the rich gateau-inspired flavour you'd expect from this release.
Black Friday Gateau Whey brings the same flavour to our classic Whey range, delivering 21g of protein per serving in the featured 1800g format.
Both come in our exclusive black packaging, and both are part of the same one-time release. The difficult bit might be deciding which one to go for.
The Black Friday Heist is on
Black Friday Gateau is at the centre of our 2026 Black Friday Heist. We've got a vault full of surprises lined up throughout November, and the new flavour is leading the charge.
There's also something extra worth getting your hands on. As part of the campaign, spend over £100 after discounts on qualifying products and you'll receive a free Black Friday Bundle worth over £100, automatically added to your basket. The bundle includes a smaller tub of Black Friday Gateau alongside a selection of Per4m favourites.
The free bundles are strictly limited. Once they've all been claimed, they're gone for good, so it's worth checking the Per4m Black Friday page for the full offer details and what's currently available.
Black Friday Gateau was made exclusively for our 2026 campaign, and there won't be another run. If you've had your eye on the black tubs, you know what to do.
