About the Product
Marvelous Nutrition's MUSCLES is a single-ingredient WPC80 Whey Protein Concentrate powder with no amino spiking, no fillers, and no proprietary blends, enriched with the DigeZyme® Enzyme Complex — a patented enzyme complex with 5 digestive enzymes (alpha-amylase, neutral protease, cellulase, lactase, and lipase) that optimizes protein digestion and absorption and maximizes gastrointestinal comfort. With approximately 24g of high biological value protein per 30g serving (WPC80 = 80% protein on a dry basis), MUSCLES is the benchmark concentrated protein in the Marvelous portfolio — the most affordable and tastiest option in the protein range, especially for users who want a creamy, tasty, and easy-to-digest protein for daily use. 2 kg (≈66 servings). Available in 10 unique and distinct gourmet flavors. Non-vegan.
Benefits
WPC80 with sunflower lecithin: premium concentrated protein without amino spiking:
MUSCLES uses WPC80 Whey Protein Concentrate — the form of whey with ~80% protein concentration on a dry basis, which retains a significant fraction of the benign fats from whey (short-chain fatty acids and CLA), carbohydrates (lactose, the main source of the natural "dairy" flavor of whey), and bioactive proteins (lactoferrin, alpha-lactalbumin, beta-lactoglobulin in higher concentrations than in WPI). The use of sunflower lecithin (instead of soy lecithin, more common in the market) as an emulsifier ensures the miscibility of the powder in water without clumps and improves the texture of the shake, while avoiding soy as a potential allergen for people with sensitivity. MUSCLES explicitly rejects amino spiking (the practice of inflating the protein value with cheap free amino acids), fillers (fillers that increase volume without nutritional value), and proprietary blends (mixtures with undeclared doses of each ingredient), ensuring total transparency in its composition.
DigeZyme® Enzyme Complex: the technical differentiator of MUSCLES vs. Bulk and Hydro Whey:
DigeZyme® (a registered trademark of Sabinsa Corporation) is the most clinically studied digestive enzyme complex in protein supplements, composed of 5 enzymes that cover the digestion of all macronutrients: alpha-amylase (digestion of starch and complex carbohydrates), neutral protease (protein digestion, complementing endogenous pancreatic proteases), cellulase (digestion of cellulose and vegetable fibers, an enzyme that humans do not produce endogenously), lactase (digestion of lactose into glucose + galactose, eliminating gastrointestinal discomfort in people with lactose intolerance even when using WPC which contains lactose), and lipase (digestion of fats/triglycerides). The inclusion of DigeZyme® in MUSCLES has multiple practical benefits: reduction of gastrointestinal discomfort associated with WPC (especially in people with partial lactose intolerance, thanks to lactase), improved digestibility and absorption of protein (additional protease accelerates protein hydrolysis into absorbable amino acids), and overall improvement in the digestion of the complete meal with which the shake is consumed. The clinical trial by Chandran et al. (2013) documented that DigeZyme® supplementation improved postprandial gastrointestinal symptoms and digestive tolerance compared to placebo.
WPC80 vs. WPI: the choice for "complete protein" with greater flavor and bioactive proteins:
The philosophy of MUSCLES as WPC80 instead of WPI or hydrolyzed WPI reflects a deliberate trade-off choice: WPC80 has a lower protein concentration (~80% vs. >90% WPI) and higher lactose and fat content than WPI, but it has a higher concentration of intact bioactive proteins (especially lactoferrin and immunoglobulins, which are partially denatured in the ultrafiltration process for WPI), a greater natural dairy flavor (lactose contributes to the characteristic "creamy" and "dairy" flavor note of WPC), and greater palatability in complex flavors (residual fat and lactose create a richer texture and mouthfeel). For athletes who use protein primarily as a daily food supplement (and not exclusively as a post-workout optimization tool), and who do not have severe lactose intolerance, WPC80 with DigeZyme® is often the most palatable and sustainable choice in the long run.
10 unique gourmet flavors: the largest flavor range in the Marvelous portfolio:
MUSCLES has the widest variety of flavors in the Marvelous protein portfolio, with 10 flavors ranging from classics (Chocolate Milkshake, Cookies & Cream, Strawberry Milkshake, Mexican Vanilla) to innovative and gourmet (Dubai White Chocolate, Chocolate Peanut Butter Cups, White Chocolate Peanut Butter Cups, Salted Caramel, Cinaboom, Banana). This diversity of flavors is a strong argument for use as a daily protein — variety prevents sensory monotony that often leads to reduced adherence to long-term supplementation. The "Dubai White Chocolate" and "Cinaboom" flavors refer to recent confectionery trends (Dubai Chocolate with pistachio and kadaif paste went viral in 2024), positioning MUSCLES as a protein updated with the most popular flavors of the moment.
Zero amino spiking, zero fillers: the transparency that defines MUSCLES:
As with BIG, the explicit rejection of amino spiking in MUSCLES is a relevant quality and transparency positioning. In the WPC market, amino spiking (adding glycine, taurine, creatine, or collagen amino acids to artificially inflate the declared total protein value on the label) is an unfortunately common practice among brands that compete solely on price. MUSCLES' commitment to "full amino acid profile without adding any amino acids or sugar" protein ensures that the 24g of protein per serving are 100% whey proteins with a complete profile of EAAs and BCAAs — not a blend of whey + cheap amino acids that inflates the label number but reduces the real biological value.
Usage
Recommended serving: Mix 1 scoop (30g) with 300 to 400 ml of cold water, shake vigorously. Consume immediately after training or at any time of day. For use as a general-purpose protein throughout the day (breakfast, snack between meals, post-workout), WPC80 with DigeZyme® is suitable for any time. For athletes with partial lactose intolerance, the lactase in DigeZyme® allows for the digestion of WPC lactose without gastrointestinal discomfort. 2 kg = ~66 servings of 30g.
