DESCRIPTION

Magnum Quattro Original - the ultimate pure isolate protein powder.

This exceptional legacy blend features four isolates, time-released for a smooth digestive experience. Quattro starts with an immediate protein flood to your bloodstream, and then gradually tapers off, creating a nitrogen balance that lasts all day, the perfect setting for lean muscle development.

Formulated with organic flaxseed and bromelain, Quattro enhances your metabolic rate, promotes stored fat utilization, and supports muscle recuperation and growth. Its flavor is as impressive as its effects, with a wide variety of delicious choices that are as smooth and enjoyable as a protein shake should be.

Quattro's formula is all-inclusive: Kosher Certified, peanut-free, gluten-free, dye-free, and perfect for those with lactose sensitivities. Whether you prefer shaking, blending, or baking, Quattro is the fuel you need to attain the results you desire.

Benefits

4 Proteins. 1 Complete System.

Most proteins hit fast. Then fade.

Many protein powders rely on a single protein source that delivers amino acids quickly but doesn't provide sustained support. Quattro combines four premium protein isolates to help keep your muscles supplied with protein longer.

Timed-release protein is the difference.

Quattro delivers 30g of protein from Hydrolyzed Whey Isolate, Whey Protein Isolate, Milk Protein Isolate, and Micellar Casein Isolate. This multi-phase blend provides both fast and sustained amino acid delivery to support recovery throughout the day.

Build more. Break down less.

With 30g of high-quality protein plus naturally occurring EAAs and BCAAs, Quattro helps support muscle repair, recovery, and the maintenance of lean muscle mass when combined with resistance training.

Clean macros. Nothing to hide.

High protein. Low fat. Low carb. Gluten free. Dye free. Every serving is built around premium protein isolates without unnecessary fillers or artificial colours.

Protein that works while you do — and while you don't.

Post-workout, between meals, or before bed, Quattro's blend of fast and slow proteins helps provide a steady source of amino acids whenever your body needs them most. Whey is rapidly digested, while casein provides a slower release profile.

Trusted by athletes since 2005.

For over 20 years, Magnum has been formulating performance supplements for athletes who demand more from their nutrition. Better Ingredients. Better Results.

Your Questions, Answered.

How many scoops should I have per day?

We recommend 1-2 scoops per day to supplement your total daily protein intake.

Can I have this if I have a dairy allergy?

No, unfortunately, Quattro is made from dairy protein. If you have lactose intolerance (a sensitivity to the sugar, lactose) you can still have Quattro as it’s virtually lactose free, and perfect for those with lactose sensitivities. For people with dairy allergies, we recommend Vegan Quattro!

Can this be taken before bed?

Yes! Quattro is designed to be taken at any time during the day. We recommend drinking Quattro after training, before bed, and as part of a meal replacement shake.
