SERIOUS MASS 5K

This is a high-calorie mass gainer designed for hardgainers and anyone struggling to hit a daily surplus. The Egypt listing shows Size: 12 LB, Serve Count: 16, and highlights 50g protein, over 250g carbs, plus creatine monohydrate per serving.
When your metabolism runs like it’s late for work and you’re trying to gain size, food alone can feel like a full-time job. Serious Mass is basically “extra meals in a shaker”: 1,250 kcal per serving, 50g protein, and 253g carbohydrates to help you push calorie intake up consistently.

It also includes creatine and glutamine sources (see label panel below), making it a popular choice for bulking phases where you want calories, carbs, and protein in one go.

Who it’s best for

• Hardgainers with a fast metabolism and low appetite

• Bulking phases where you need high calories + high carbs without cooking another meal

• Lifters who want a gainer they can scale (half serving vs full serving) depending on goals
