Metabolic Mass - 42g protein + 590kcal dual-protein mass gainer

DY Nutrition Metabolic Mass Gainer 6kg is the brand's mid-calorie mass gainer built for trainees who want substantial calorie surplus without the extreme 1000+ kcal load of heavyweight gainers. Each 150g serving delivers 590 calories, 42g of protein, 99g of carbohydrates and 2.9g of fat. The 6kg tub provides 40 servings.

The protein base provides 42g per serving from multi-source dairy proteins for sustained amino acid delivery across a 3-4 hour window. The carbohydrate base at 99g per serving is built around fast-digesting maltodextrin for post-training glycogen replenishment plus slower-releasing sources, with sugars contained at 7.5g. The 2.9g fat keeps the macro split lean compared to many gainers that run 10-15g fat per serving.

What separates Metabolic Mass Gainer from a heavyweight 1000-calorie gainer is the dosing flexibility. At 590 calories per serving it sits between a protein shake and a hard-gainer formula - trainees can take one serving for a moderate surplus or two servings for a heavier bulking phase. The 40-serving pack format suits committed bulking cycles or shared-household scenarios.

Metabolic Mass Gainer suits trainees in moderate bulking phases who want calorie support without the extreme 1000-calorie serving size, lifters who use shakes as meal-add-ons rather than meal replacements, and athletes managing a controlled surplus rather than a maximum-calorie surge. It is not for trainees needing extreme calorie density - heavyweight gainers cover that. Contains milk and soy.

Heavyweight alternative: XL Nutrition XTRA Mass Gainer 5.2kg (50g protein, 1000kcal per 260g scoop) for trainees needing maximum calorie support per shake.

Key Benefits

590kcal Per Serving

590 calories and 42g of protein deliver the calorie surplus required for muscle mass gain without excessive fat accumulation.

6kg Best Value Tub

40 full servings from a 6kg tub makes Metabolic Mass one of the best value mass gainers for dedicated bulk phases.

Dual Protein Source

Whey Protein Concentrate and Milk Protein deliver both fast and sustained release amino acids for continuous muscle recovery throughout the day.

Low Sugar

Just 7.5g of sugar per serving with complex carbohydrates for sustained energy rather than empty sugar calories.

Frequently Asked Questions

Who is DY Nutrition Metabolic Mass Gainer best suited to?

When should I use DY Nutrition Metabolic Mass Gainer?

The best time to use DY Nutrition Metabolic Mass Gainer depends on the format and the rest of your routine, but most people get more from it when it sits in a consistent daily or around-training slot. Consistency usually matters more than chasing a perfect time.

What makes DY Nutrition Metabolic Mass Gainer a practical option?

DY Nutrition Metabolic Mass Gainer is practical because it is built to help you push calorie intake higher when food falls short without adding much friction to the rest of the day. That ease of use is often what makes a product stay in the routine long enough to be worthwhile.
