Quick answers
Is this right for you?
Who is it for?
Protein Works Vegan Mass Matrix 360 Gold is designed for hard-gainers and anyone in a dedicated bulking phase who struggles to eat enough calories. Mass gainers combine protein with carbs and calories to support weight gain and muscle growth during intense training blocks.
What can you expect?
A calorie-dense shake designed to help you gain weight. Mass gainers pack protein alongside a significant amount of carbohydrates and calories per serving. Servings tend to be larger than standard protein powders, so expect thicker shakes and bigger scoops. With 25g of protein per 100g (around 50g per 200g serving), Protein Works Vegan Mass Matrix 360 Gold sits in a competitive position for a mass gainer product.
What else do you need to know?
