Full Fraction Disclosure
EVERYTHING YOU NEED TO KNOW
Full transparency. Full ingredient disclosure.
Full fraction disclosure. Most whey makers tell you the protein content and call it a day. This formula discloses the exact breakdown of both the whey concentrate (36% β-Lactoglobulin, 10% α-Lactalbumin, 3% Immunoglobulin G, 15% Glycomacropeptides, 25% BCAAs, 19% Glutamic Acid) and the whey isolate (69% β-Lactoglobulin, 14% α-Lactalbumin, 25% BCAAs, 18% Glutamic Acid). Ion-exchanged, ultra-filtration processing preserves the naturally occurring immunoglobulins, glycomacropeptides, and bioactives. Sweetened with stevia and monk fruit — no aspartame, acesulfame-K, sucralose, maltodextrin, or added sugar.

How this product is made and what we verify before it ships.
FDA-Registered Manufacturing
Produced in a US manufacturing facility registered with the FDA for dietary supplement production. The registration is independently maintained and subject to federal inspection.
Made Under cGMP Standards
Production adheres to current Good Manufacturing Practices, the federal framework that governs identity, purity, strength, and composition of every batch.
Grass-Fed Sourcing
The whey is sourced from cattle raised on pasture, eating grass as their primary diet — not finished on grain in feedlots. Same source as the Maxis Vanilla Whey.
Ion-Exchange + Ultra-Filtration Processing
The gentlest commercial processing methods for whey protein. Preserves the native bioactive fractions (immunoglobulins, glycomacropeptides, lactoferrin pathway) that aggressive heat- and acid-based processing destroys.
Full Fraction Disclosure
Every major protein fraction is broken out on the label — both for the concentrate and the isolate. β-Lactoglobulin, α-Lactalbumin, Immunoglobulin G, Glycomacropeptides, BCAAs, and more, each at their disclosed percentage. Most wheys hide this. We disclose it.
Clean Sweetener System
Sweetened with Sweta™ stevia and luo han guo (monk fruit) — no sucralose, aspartame, acesulfame-K, maltodextrin, fructose, or added sugar. Explicitly called out on the label.
We don't cite studies to impress — we cite them so you can verify. Each finding maps to peer-reviewed, publicly available research.
Protein quality scores
Whey scores at the top of the three major protein quality scoring systems used in nutritional science: PDCAAS 1.0 (the WHO/FAO standard, the maximum possible score), Biological Value 100 (the reference standard every other protein is measured against), and Protein Efficiency Ratio 3.2 (highest among common dietary proteins).

Muscle protein synthesis
Whey protein has been extensively studied in randomized trials for its effects on post-exercise muscle protein synthesis, recovery, and resistance training adaptations. A landmark 2009 study found whey produced a significantly greater MPS response than casein or soy, and a 2012 meta-analysis confirmed protein supplementation augments muscle mass and strength gains during resistance training.

Processing and bioactives
Ion-exchange and ultra-filtration processing preserve the native protein fractions and bioactive compounds (immunoglobulins, glycomacropeptides, lactoferrin) that aggressive heat-based processing damages. Standard HTST pasteurization alone denatures roughly 59% of lactoferrin and 12% of IgG — losses that compound when whey is further processed with heat and acid.

Sweetener choice matters
Research has linked common artificial sweeteners — including sucralose, aspartame, and saccharin — to disruption of the gut microbiome and glucose intolerance. A landmark 2014 Nature study showed non-caloric artificial sweeteners induced glucose intolerance by altering gut microbiota in both mice and human subjects. Because most protein powders rely on these sweeteners by default, formulation choice has downstream effects beyond taste.

Honest expectations. Here's what consistent daily use typically looks like.
Post-workout
30–60 minutes after training
Whey is one of the fastest-absorbing protein sources available. Peak amino acid availability hits within 60–90 minutes — ideal for the post-training recovery window.
Daily
Closing the protein gap
Active adults need 0.7–1g of protein per pound of body weight daily. A scoop fills the gap between what whole foods provide and what training demands.
Weeks 4–8
Consistent training adaptations
Combined with resistance training, daily protein intake supports the muscle protein synthesis required for strength and body composition changes.
Ongoing
Foundational nutrition
Not a short-term protocol. A daily tool for hitting protein targets alongside whole foods, training, and sleep.
Every MAXIS product is designed to work alongside the others. Here's how Grass-Fed Whey Protein (Chocolate) pairs with what we carry.
Pairs with
Creatine Monohydrate
Creatine and whey are the two best-studied supplements for resistance training. Creatine for power and strength; whey for the protein synthesis that builds on top. The foundation of any serious training stack.
Pairs with
Grass-Fed Pasture-Raised Beef Collagen (Chocolate)
Whey for muscle synthesis. Collagen for connective tissue. Both are protein, with completely different amino acid profiles and uses. Most active adults benefit from both — whey for performance, collagen for recovery and longevity.
Pairs with
Grass-Fed Whey Protein (Vanilla)
Rotate flavors so you actually drink it daily. Chocolate for the morning shake, vanilla for everything else — oatmeal, smoothies, baking. Same grass-fed source, same processing, same fraction disclosure.
Because the fractions are what actually matter. Whey protein isn't one thing — it's a collection of bioactive proteins with different functions. β-Lactoglobulin and α-Lactalbumin are the major fractions. Immunoglobulins support immune function. Glycomacropeptides have unique bioactive properties. Most brands hide this information because their formulas are commodity whey blends. We disclose it because the breakdown is the proof.
It's the gentlest commercial processing method for whey protein. Heat- and acid-based processing damages the delicate bioactive proteins (immunoglobulins, lactoferrin pathway, glycomacropeptides). Ion-exchange uses electrical charge to separate proteins from milk fluid; ultra-filtration uses fine membranes. Together they preserve the bioactive structure that makes whey functional.
Neither — they have different strengths and this formula uses both. Concentrate is richer in bioactives (immunoglobulins, glycomacropeptides). Isolate is more protein-dense and lower in lactose. The blend gives you the bioactive richness of concentrate plus the density of isolate. Best of both.
Same quality tier, slightly different macros. The vanilla is 19g protein per scoop. This chocolate is 17g per scoop because the cocoa and flavor system take up space. Every flavored protein on the market makes this trade — that's not a flaw, it's physics. Same grass-fed source. Same ion-exchange processing. Same fraction disclosure. Same clean sweetener system.
The cattle the whey is sourced from are raised on pasture, eating grass as their primary diet — not finished on grain in feedlots. Grass-fed dairy has been shown to have different fatty acid profiles than conventional dairy. The cattle are also rBGH-free, meaning they aren't treated with recombinant bovine growth hormone.
Stevia (Sweta™ brand — selected for no licorice aftertaste) and luo han guo fruit extract (monk fruit). Both are natural, zero-calorie sweeteners. No sucralose, no aspartame, no acesulfame-K, no maltodextrin, no added sugar.
Soy lecithin is used as an emulsifier at less than 1% of the total formula — it's what makes the powder mix smoothly into water or milk without clumping. Standard practice in premium wheys. Not enough to be a meaningful source of soy, but worth flagging if you have a severe soy allergy.
Whey hits the ceiling on every major protein quality measure: PDCAAS 1.0 (max possible score, the WHO/FAO standard), Biological Value 100 (reference standard), and Protein Efficiency Ratio 3.2 (highest among common proteins). It's the most-studied protein for muscle protein synthesis and post-training recovery.
