Analysis

The mass gainer delivers a large calorie load with substantial protein and carbohydrates in one serving. That composition can help users who struggle to eat enough for weight gain or high-volume training.

Sodium is substantial and may help replace heavy sweat losses, while potassium is modest and its form is not named. Chromium uses a branded yeast matrix, but the active yield and elemental interpretation are not fully clear.

The formula is poorly aligned with weight loss or routine heart support because the carbohydrate load is very high. Buyers seeking protein, electrolytes, or chromium alone can find more focused and economical products.

Who is it for
  • Athletes deliberately pursuing weight gain
  • People who need a large calorie surplus
  • Users wanting high protein and carbohydrates together
Best for
  • Mass-gain nutrition
  • Post-training calorie replacement
  • High-volume training diets

Pros

  • Substantial protein
  • Large calorie contribution
  • Chromium amount is stated
  • Sodium may suit heavy sweat replacement

Cons

  • Very high carbohydrate load
  • Potassium is modest
  • Mineral forms are unclear
  • Poor fit for weight loss or heart goals

Warnings

  • The very high carbohydrate load is unsuitable for people who need strict carbohydrate control.
  • The substantial sodium amount may not fit sodium-restricted diets.

Nutrient quality

59 Moderate impact

Large protein and carbohydrate amounts suit intentional mass gain. An aggressive energy load, high sodium, and weak alignment with several listed goals reduce suitability.

.

Ingredient transparency

64 Moderate impact

Some core nutrition amounts are clear enough to evaluate. Missing complete ingredients, use directions, or blend details create meaningful gaps.

.

Customer satisfaction

56 Moderate impact

Aggregate satisfaction data are favorable. Specific firsthand comments were not supplied, leaving repeated complaints and purpose fit uncertain.

.

Value for money

58 Moderate impact

Formula weaknesses limit value for routine use. Better-balanced or more transparent alternatives are likely to be more practical.

Highest effect
A- Goal FitB+ Strength of SupportB+ CoverageA- Formula Quality

A large serving of protein and carbohydrate directly supports calorie intake, muscle repair, and glycogen replacement during mass-gain training. Protein and carbohydrate nutrition is well established for recovery and weight gain.

The serving is highly calorie dense and the protein source is not identified in the supplied facts. Athletes should match the large carbohydrate and sodium load to their energy needs rather than treat it as a general-purpose recovery drink.

Report overview
Sodium · 600 mg OverallScore68
D- Active Ingredient Quality & BioavailabilityA Dose, Safety & Label TransparencyB- Value

The sodium amount suits athletic replenishment, but the source is undisclosed and the potassium form is not identified. No magnesium, trace-mineral complex, or buffering compound is shown, while the very high carbohydrate load may be impractical during many workouts. The serving is costly as an electrolyte source, although the mass-gainer format includes substantial non-electrolyte nutrition.

Chromium (Chromium 454(R) Bio-Organic Yeast Matrix) · 200 mcg OverallScore59
C- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

The branded yeast matrix has traceable sourcing, though yeast-based chromium can vary in active content. The disclosed 200 mcg amount fits the standard metabolic-support range, although the label does not distinguish elemental weight from compound weight. Most of the serving cost reflects a mass-gainer formula rather than chromium quality, so chromium-specific cost efficiency remains poor after normalizing to a standard amount.

Potassium · 165 mg OverallScore25
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyF Value

No potassium compound is named, leaving form quality and bioavailability uncertain. The 165 mg serving is moderate but falls well short of a high-potency potassium dose. A very high serving cost makes it inefficient for potassium supplementation.

Carnivor Mass Chocolate Fudge

MuscleMeds
The formula closely matches the original with 50 g of protein, 125 g of carbohydrate, and a high-calorie serving, while also listing substantially more potassium. It keeps chromium and the same mass-gainer structure, though the sodium amount is higher.

Isopure Zero Carb Strawberries & Cream

Nature's Best
The serving keeps 50 g of protein while removing the original’s large carbohydrate load, which may suit someone prioritizing protein over extra calories. It is not a like-for-like mass gainer because the serving supplies far fewer calories.
