Heavy Weight Ingredients

ModCarbTM

A nutrient-rich grain matrix of oat bran, quinoa, amaranth, buckwheat, and millet provides complex carbohydrates for controlled absorption and steady energy, ideal for fast metabolisms.

Hard Gainer Protein System

A blend of WPC, calcium caseinate, WPI, and whey peptides releases protein over time to support sustained muscle building. Added glutamine and BCAAs further promote recovery and growth.

Omega-Rich blend

MCT oils and Omega fats supply calorie-dense energy, delivering 9 calories per gram compared to 4 from proteins or carbs. Omega fats are known as good fats, supporting overall health, heart function, and vitality.

DigeZyme®

This digestive enzyme blend helps break down proteins into amino acids for better absorption, making the formula easier to digest. 

How to Take Heavy Weight Protein:

Mix 220g (6 scoops) with 400–500ml of skim milk. Consume in one full serve in the morning, between meals, or around workouts. You may also split it into two half serves. It can be enjoyed on its own or blended into a smoothie.
