Three-Product Digestive Performance Stack

Three Products. One Mealtime Protocol.†

A Digestive Stack Designed for Amino Acid Absorption, Recovery, and Muscle Growth†

The Muscle Building Stack combines three complementary digestive support products into a single mealtime protocol, each targeting a distinct aspect of nutrient breakdown and absorption.†

✓ MassZymes (3 bottles × 250 caps) — a full-spectrum digestive enzyme formula featuring 100,000 HUTs of protein-digesting proteases per capsule, plus amylase, lipase, cellulase, lactase, phytase, and more, with AstraZyme™ for enhanced enzyme delivery. 100% plant-based.†
✓ P3-OM (1 bottle × 120 caps) — a patented probiotic and prebiotic synbiotic formula featuring Lactobacillus plantarum OM, a proteolytic strain designed to support gut flora balance, protein digestion, and digestive comfort. No refrigeration required.†
✓ HCL Breakthrough (1 bottle × 90 caps) — a plant-based betaine hydrochloride formula derived from beetroot, combined with a 5-enzyme digestive blend and a full-spectrum trace mineral complex to help support healthy stomach acid levels and mineral absorption.†

Important: The Muscle Building Stack is a complementary medicine designed to support general digestive wellbeing and nutrient absorption. It is not a treatment for any medical condition, digestive disorder, or diagnosed health condition. Always consult your healthcare professional before starting any new supplement regimen.

Suggested Use

How to Take the Muscle Building Stack

💊 MassZymes

Full-Spectrum Digestive Enzymes

Take 5–10 capsules with each meal (based on meal size and calorie content) to support the breakdown of proteins, carbohydrates, and fats. May also be taken between meals for different purposes — consult your healthcare professional.†

🧬 P3-OM

Proteolytic Probiotic

Take 3 capsules with each meal to support microbial balance and protein digestion. No refrigeration required. If taking antibiotics or antibacterial supplements, space P3-OM at least one hour away.†

🔬 HCL Breakthrough

Stomach Acid Support

Take 2–4 capsules with each meal (based on meal size and calorie content), during or within 30 minutes of eating. Start with 1 capsule and adjust based on individual response. Do not dissolve capsules in beverages.†

💡

Protocol tip: Take all three products together with each meal for comprehensive digestive support. Always read the label and follow the directions for use, or take as directed by your healthcare professional.†

Why Choose This Stack

What Makes the Muscle Building Stack Different

Three Complementary Digestive Products†

MassZymes targets enzyme-level protein breakdown. P3-OM supports gut flora balance and proteolytic activity through a patented probiotic strain. HCL Breakthrough addresses the first stage of digestion by helping support healthy stomach acid levels. Together they target three distinct steps in the nutrient absorption process.†

High-Potency Protease Concentration in MassZymes†

MassZymes contains 100,000 HUTs (Hemoglobin Units on the Tyrosine basis) of protein-digesting enzymes per capsule — a notably high concentration compared to many standard enzyme supplements. Formulated with multiple protease forms active across different pH levels throughout the digestive tract.†

Patented Proteolytic Probiotic Strain in P3-OM†

P3-OM features Lactobacillus plantarum OM, a unique patented strain that produces proteases to support protein digestion and assimilation. Unlike many transient strains, L. plantarum OM can multiply inside the gut — meaning you may not require as many colony-forming units as other probiotic supplements. Combined with fructo-oligosaccharides (FOS) prebiotic fibre for a synbiotic effect.†

Plant-Based Betaine HCl — No Pepsin in HCL Breakthrough†

HCL Breakthrough uses betaine hydrochloride derived from beetroot to help support stomach acidity levels, alongside a 5-enzyme blend (Protease 3.0, Protease 4.5, Amylase, Lipase, Cellulase) and a proprietary trace mineral complex. Unlike many HCl supplements, it contains no pepsin (an animal-derived enzyme), making it suitable for vegans and vegetarians.†

AstraZyme™ Enhanced Delivery in MassZymes†

MassZymes features AstraZyme™ — a proprietary plant-derived compound extracted from Panax ginseng and Astragalus membranaceus — formulated to support enzyme effectiveness and nutrient absorption.†

Quality Manufacturing Standards

All three products are made in GMP-certified facilities using premium, globally sourced ingredients. 100% plant-based, vegan-friendly, gluten-free, soy-free, dairy-free, and free from artificial additives. Backed by a 90-Day Money Back Guarantee through BIOptimizers Australia.

MassZymes: Complete Ingredient Information

Protease Blend (100,000 HUTs per capsule)

Multiple protease forms — including Protease 4.5, Protease 6.0, and Protease 3.0 — that work at different pH levels throughout the digestive tract to support protein breakdown into amino acids.†

AstraZyme™

Proprietary blend of extracts from Panax ginseng and Astragalus membranaceus, formulated to support enzyme effectiveness and nutrient absorption.†

Additional Digestive Enzymes

Amylase (carbohydrate breakdown), Lipase (fat breakdown), Cellulase (plant fibre breakdown), Glucoamylase, Invertase, Lactase (dairy support), Phytase (mineral release from grains and legumes), Alpha Galactosidase, Beta Glucanase, Hemicellulase, Pectinase, and Xylanase.†

Other Ingredients

Rice bran (enzyme stability), hypromellose (vegetable capsule), microcrystalline cellulose. Free from gluten, dairy, soy, and artificial fillers.

What's Inside — P3-OM

P3-OM: Complete Ingredient Information

Lactobacillus plantarum OM (Patented Strain)

A carefully selected, freeze-dried proteolytic probiotic strain designed to survive stomach acid, support protein digestion, and promote gut flora balance. Can multiply inside the gut, providing ongoing support beyond the initial dose.†

Fructo-oligosaccharides (FOS)

A plant-based prebiotic fibre that feeds and supports the growth of beneficial gut bacteria. Works synergistically with L. plantarum OM to create a probiotic + prebiotic synbiotic effect.†

Stabilised Rice Bran

A hypoallergenic stabilising agent that helps extend shelf life and prevent premature activation by moisture, supporting potency without refrigeration.

Vegetable Capsule

Plant cellulose and water. Vegetarian-friendly and free from animal products, gluten, and common allergens.

Important Note: Cultured on Milk-Containing Medium

While P3-OM is lactose-free, the probiotic culture is grown on a milk-containing medium during production. Those with severe milk allergies should consult their healthcare professional before use.

What's Inside — HCL Breakthrough

HCL Breakthrough: Complete Ingredient Information

Betaine Hydrochloride (from Beetroot)

Beetroot-derived betaine HCl releases hydrochloric acid in the stomach to help support healthy stomach acidity levels. Provides the same type of acid the stomach produces naturally. 100% plant-based — contains no pepsin.†

5-Enzyme Digestive Blend

Protease 3.0, Protease 4.5 (protein digestion at multiple pH levels), Amylase (carbohydrate support), Lipase (fat breakdown), and Cellulase (plant fibre support) — five plant-based enzymes for comprehensive digestive support across macronutrient categories.†

Full-Spectrum Trace Mineral Complex

A proprietary trace mineral blend providing cofactors for enzyme function. May help support the absorption of iron, calcium, magnesium, zinc, copper, and manganese.†

Other Ingredients

Rice extract, vegetable cellulose (capsule), water. Free from gluten, dairy, soy, sugar, and artificial ingredients.
