Four isolate proteins. Almost 2.8g leucine. Better recovery all day.
Magnum Quattro is a protein blend that focuses on giving you high-quality protein from sources with different digestion speeds, so one shake covers quick post-workout needs and longer recovery support. It uses four types: whey protein isolate, milk protein isolate, micellar casein, and egg protein isolate. Each one digests differently and brings its own amino acids. Whey isolate hits fast, boosting amino acids in your blood right after you drink it. Micellar casein goes slow, gelling up in your stomach for a steady release. Milk protein isolate mixes whey and casein naturally, and egg isolate adds easy-to-digest aminos.
The aminos are where it shines. Each scoop has 2,757mg leucine, 1,490mg valine, and 1,463mg isoleucine. Leucine is the star for starting muscle repair—it flips on the mTOR pathway, which is your body's signal to fix and grow muscle. Studies show 2.5-5g of leucine works best, and Quattro delivers that from real protein, not cheap add-ins. Valine and isoleucine help with muscle energy, blood sugar, and bouncing back, all wrapped in a full protein setup with the other essentials for actual building.
The full essential aminos are strong too. You get lysine at 2,419mg, threonine at 1,773mg, methionine at 585mg, phenylalanine at 800mg, histidine at 454mg, and tryptophan at 427mg. This matters because leucine can signal muscle protein synthes
Magnum Quattro by Magnum Nutraceuticals contains 170mg Calcium, a standard dose for muscle protein synthesis.
Key Highlights
- 30g protein per serving from four isolates—this isn't your basic whey. Mixing whey isolate, milk isolate, micellar casein, and egg isolate means you get quick aminos right away and a steady flow for hours after.
- 2,757mg leucine per scoop—that's the amino that really sparks muscle repair. It kicks off the mTOR pathway, and this amount is right in the zone for getting your muscles building.
- Solid BCAA setup with 2,757mg leucine, 1,490mg valine, and 1,463mg isoleucine. So Quattro isn't just tasty protein—it delivers the branched-chains that help with recovery, muscle fuel, and fighting breakdown.
- Full essential aminos, beyond just leucine. Lysine at 2,419mg, threonine at 1,773mg, methionine at 585mg, phenylalanine at 800mg, histidine at 454mg, and tryptophan at 427mg give you everything needed to build muscle after the signal starts.
- Whey protein isolate for the fast part—perfect when you need aminos quick after a workout. It digests and absorbs fast, making Quattro great right after training, not just as a snack.
- Micellar casein for longer release. It digests slower than whey, so this shake fills you up more and works for between meals or bedtime better than straight fast protein.
- Milk protein isolate brings a natural whey and casein mix in one. That smooths out digestion and makes the shake more useful than plain whey isolate.
- Egg protein isolate completes the blend with another easy-digesting full protein. Eggs are known for great aminos, and this adds variety over simple two-protein mixes.

Who Is This For?
- Gym rats hitting 4-6 sessions a week who want one protein for after lifts and snacks. Whey isolate gives quick aminos, micellar casein and milk isolate extend it so you're covered longer than basic whey.
- Builders in growth phases chasing recovery, fullness, and steady protein. 2,757mg leucine helps trigger muscle repair, and full essential aminos supply the goods.
- Folks cutting or recomping who need high protein without extra macros from meal shakes. Isolate focus keeps cals, carbs, fat in check better than concentrates.
- Busy types skipping meals who want more than watery whey. Fast and slow mix makes it filling for long stretches.
- Nighttime hunger hitters wanting sustained protein without extra casein buy. Micellar casein and milk isolate slow release for better evening use.
- People avoiding spiked or weak proteins. Disclosed aminos like almost 2.8g leucine and full essentials show real quality, not hype.
How to Use
Mix one rounded scoop with 8-12 oz cold water for light, or less for thick. Best after training, between meals, or 30-60 minutes before bed for overnight feed. Post-workout rocks because whey isolate hits quick, and casein/milk keep it going. If new to blends or sensitive gut, try half first. Fine with food, but solo digests faster for targeted hits. Stacks great with creatine, carbs around workouts, or greens if needed. No cycling; use daily. Keep it sealed, cool, and dry for best mixing.
What to Expect
First 0-10 minutes: you feel the texture, how full it makes you, and it settles nice. No stims, so no hype—just a solid start over weak drinks. 10-40 minutes: whey isolate ramps up aminos early, with slower ones waiting. 40-120 minutes: here's where it beats plain whey, as milk isolate and micellar casein keep feeding and filling you up. Days 1-7: biggest win is sticking to protein goals and recovering better without skips. Weeks 2-4: you see it in steady training, fewer protein misses, and better muscle hold when diet's dialed. It's foundational, so gains build over time, not overnight.

Frequently Asked Questions
How much protein does Magnum Quattro provide per serving?
Magnum Quattro provides roughly 30g protein per serving from its four-protein isolate matrix. That protein comes from whey protein isolate, milk protein isolate, micellar casein, and egg protein isolate rather than from a single-source whey formula.
How much leucine is in Magnum Quattro?
Each serving delivers 2,757mg leucine. That is a meaningful number because leucine is the primary amino acid that activates the mTOR pathway and helps trigger muscle protein synthesis after training.
Is Quattro better after workouts or before bed?
It works well for both. The whey isolate fraction makes it effective post-workout for faster amino acid delivery, while the micellar casein and milk protein isolate fractions make it more sustained and better suited to before-bed use than a whey-only product.
What makes this different from a standard whey isolate?
A standard whey isolate is mostly a fast protein. Quattro combines fast whey with slower milk protein isolate, micellar casein, and egg isolate, so it gives you a broader amino acid release curve and usually a more filling, meal-like recovery option.
Does Magnum Quattro contain digestive support?
Yes. It includes bromelain, a digestive enzyme often used to support protein breakdown and improve the user experience of higher-protein formulas.
Can I use Quattro as a meal replacement?
It can help bridge missed meals because it is more substantial than a basic whey isolate, but it is still primarily a protein supplement rather than a full meal replacement. If you use it in place of a meal, adding carbs or healthy fats can make it more nutritionally complete.
Does this product contain dairy or egg allergens?
Yes. The formula contains whey protein isolate, milk protein isolate, micellar casein, and egg protein isolate, so it is not suitable for anyone with dairy or egg allergies.
Is Quattro a good choice during a cut?
Yes, especially if you need to keep protein high while controlling calories. An isolate-forward protein blend helps support lean mass retention and recovery without the heavier fat and carb load often seen in less refined protein formulas.
Can I stack Quattro with creatine?
Absolutely. Creatine monohydrate complements Quattro well because creatine supports phosphocreatine replenishment and strength output, while Quattro covers the amino acids needed for muscle repair and growth.
Is the amino acid profile a good sign of protein quality?
Yes. The disclosed amino acid panel—especially the 2,757mg leucine, 1,490mg valine, 1,463mg isoleucine, and strong essential amino acid spread—supports the conclusion that this is a legitimate complete protein formula rather than an amino-spiked label.
