Frequently Asked Questions

Absolutely. Musashi 100% Whey mixes exceptionally well into oats, breakfast bowls, macro-friendly baking recipes, or blended fruit smoothies.

FAQs

Musashi 100% Whey Protein Powder Frequently Asked Questions

What type of protein matrix is used in Musashi 100% Whey?

Musashi 100% Whey features a premium, multi-stage whey protein blend combining Whey Protein Concentrate (WPC) and Whey Protein Isolate (WPI). This strategic pairing utilizes the rapid absorption velocity of cross-flow micro-filtered WPI to instantly deliver amino acids to tissues, combined with the intermediate absorption release of premium WPC.

What are the exact macronutrient and amino acid metrics per serving?

Every standard 33g level scoop delivers an exceptionally clean, macro-optimized performance profile engineered to fit flawlessly into any lean training block:

Protein: 25.3g of complete, highly bioavailable whey protein.

Essential Amino Acids (EAAs): 11.9g of naturally occurring complete EAAs.

BCAAs: 5.6g of Branched-Chain Amino Acids (featuring a high concentration of L-Leucine) to fuel muscle protein synthesis.

Macros: Only 131 calories, 2.0g of total fat, and a minimal 2.4g of low-glycemic carbohydrates per serve.

Will Musashi 100% Whey cause stomach bloating or heavy digestion?

No. Musashi specifically eliminates post-shake digestive heavy feelings or stomach bloating by infusing the blend with 0.15% Papain. Papain is a natural, plant-based digestive enzyme derived from papaya that actively breaks down complex protein peptide bonds into rapidly absorbable free-form amino acids, ensuring smooth, light gastric comfort.

 

How many servings are in the 330g, 900g, and 2kg container sizes?

Based on the standard 33g daily level scoop, the exact serving counts available at Sprint Fit include:

330g Tub: Provides 10 full servings (perfect for short trips or trying out a new flavor).

900g Tub: Provides 27 full servings (a practical, highly portable monthly training supply).

2kg Tub: Provides a massive 60 full servings (delivering the absolute best long-term cost-per-scoop value for daily athletes).

Is Musashi 100% Whey certified safe for drug-tested athletes?

Yes. Musashi is a trusted industry benchmark for purity across Australasia. This product is strictly Informed-Sport certified, meaning every single production batch undergoes rigorous independent laboratory screening for banned substances. Elite competitive sports players across New Zealand can consume it with absolute confidence.

Can I use Musashi 100% Whey on my non-training rest days?

Absolutely. Hitting your daily baseline protein targets is just as critical on rest days to support continuous tissue repair. Consume 1 scoop first thing in the morning or between major meals on non-training days to give your body a clean, steady supply of essential recovery nutrients.

What are the available flavors at Sprint Fit, and how is the mixability?

Musashi 100% Whey is instantized to dissolve smoothly in a shaker bottle with zero clumping or chalky residue. Top-rated, customer-favorite flavors across NZ include Chocolate Milkshake, Vanilla Milkshake, and Salted Caramel. Pro-tip: For an incredibly rich, dessert-style treat, mix your scoop with chilled almond or oat milk.
