About this product

The large calorie and carbohydrate contribution suits people trying to add substantial food energy alongside training. A serving lists 1,250 calories, 252 g carbohydrate and 50 g protein, making portion size central to whether it fits. Protein supports exercise-related repair, while 3 g creatine monohydrate may support repeated hard efforts with regular use.

The vitamin and mineral additions can help fill intake gaps, but they are secondary to the calorie, protein and creatine contribution. Calcium at 600 mg and phosphorus at 590 mg add substantial mineral amounts, while vitamin D at 5 mcg provides a smaller contribution. The 8 mg iron uses ferrous fumarate, which has stomach-tolerance limitations, and the high calcium content may compete with its absorption.

The ingredient findings also record 9 g added sugar and an artificial sweetener marker. Choline's usable yield and some mineral-source proportions remain unclear, limiting close comparisons of the extras. Many added nutrients offer poor individual value at the whole-serving cost, while the supplied information does not establish how competitively the main calories and protein are priced.

Who is it for
  • People struggling to meet substantial calorie needs during training
  • Active adults seeking protein and creatine alongside a high carbohydrate intake
Best for
  • Adding substantial calories
  • Exercise-related protein intake and repeated high-intensity efforts

Pros

  • Protein and creatine directly support the training purpose
  • Large carbohydrate contribution can help meet high energy needs
  • Primary nutrition amounts are clearly disclosed

Cons

  • A full serving may exceed modest calorie needs
  • Added sugar and an artificial sweetener are recorded
  • The usable choline amount is unclear
  • Main calorie and protein value cannot be judged from the supplied comparisons

Warnings

  • A full serving adds 1,250 calories and 252 g carbohydrate; adjust portions to the intake target to avoid an unintended surplus.
  • The 570 mg sodium serving deserves attention when following a sodium-limited plan.
  • Ferrous fumarate may be less comfortable on the stomach, and calcium in the same serving can compete with iron absorption.

Product analysis

53 out of 100

Serious Mass Chocolate supplies protein for muscle repair and creatine for repeated high-intensity exercise with sustained use. Many of its added vitamin and mineral portions offer less favorable value.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality46

The forms vary in quality, with favorable active biotin, B5 and zinc alongside less favorable copper and some mineral mixtures. Many other forms remain unspecified or cannot be reliably compared here.

Ingredient Transparency70

Total nutrient amounts and many forms are disclosed. The calcium and phosphorus source proportions remain unspecified, and total protein does not establish separate whey or casein amounts.

Value For Money31

Many added nutrients offer less favorable value at the serving cost, especially selenium, chromium and glutamine. Value for the main protein and carbohydrate portions remains uncertain.

Customer Satisfaction87

Customers generally rate it favorably. A very large review base gives that satisfaction pattern broad support.

Product Focus39

Protein supports exercise-related nutrition, and creatine supports repeated high-intensity efforts with sustained use. The broad vitamin and mineral mix is most useful when it fills dietary gaps rather than adding to already adequate intake.
