💪 Why Use Serious Mass?

Gaining weight isn’t complicated — but it is hard if you’re not eating enough.

Serious Mass solves that by giving you a large calorie boost in one shake, helping you stay in a consistent surplus without forcing huge meals.

This makes it ideal for:

• Hard gainers / fast metabolisms
• Bulking phases
• People who struggle to eat enough food daily
• Post-workout recovery + calorie replenishment

📦 Directions for Use

Mix 2 heaping scoops with 500–700ml of water or milk.

Tip: Start with half a serving and build up — full servings are very high in calories.
