4 Proteins. 1 Complete System.

Most proteins hit fast and fade. Quattro delivers a TIMED RELEASE OF PROTEINS across hours - not minutes.

Four piles of protein powder, labelled whey protein hydrolysate, whey protein isolate, milk protein isolate and micellar casein

  1. Whey protein hydrolysate

    Already broken down, so it's the first to arrive.

  2. Whey protein isolate

    Fast and clean, right after training.

  3. Milk protein isolate

    Picks up as the whey fades, through to your next meal.

  4. Micellar casein

    The slow one. Still releasing protein hours later.

Average digestion times, as printed on the Quattro label.

What Quattro customers say

“I’ve used Quattro for over 10y now as my go-to for everything from baking, post-workout & so much more. I’ve put so many friends onto this protein as well & they fully agree with me - it’s simple the best & smoothest protein you’re ever going to have!”

Questions.

When should I take Quattro?

Right after training, as part of a meal-replacement shake, or baked into oats and pancakes. Take 1 to 2 servings with 1 to 2 cups of water or your drink of choice.

Why four proteins instead of one?

They digest at different speeds: whey protein hydrolysate in up to 1.5 hours, whey protein isolate up to 2, milk protein isolate up to 4 and micellar casein up to 6. One scoop keeps supplying protein for longer than a single fast whey.

How much protein is in a scoop?

30 g of protein in a 39 g scoop, with 150 calories, 5 g of carbohydrate, 1 g of sugar and 1 g of fat. A 2 lb tub has 23 scoops.

Is it gluten free?

Yes. Quattro is gluten free and dye free. It contains milk, and it's made in a facility that also processes soy, sesame, peanuts, tree nuts, fish, shellfish and wheat.

Can I change or cancel a subscription?

Yes. Subscribe & save takes 15% off and delivers every 4, 6 or 8 weeks. You can skip, pause or cancel anytime.
