Who Should Use Mass Gainers?

Best fit: hardgainers (fast metabolism), athletes with high energy expenditure, busy people who can't eat enough, and anyone recovering from injury or illness.

Skip if: you're overweight, have a slow metabolism, already hit your calorie target from food, or your goal is fat loss.

What to Look for in Mass Gainers

Look for: 500–1200 kcal per serving · 40–60g quality whey/casein · slow carbs (oats, starches) · MCT or flaxseed fats · sugar under 30g (ideally <15g).

Avoid: sugar over 50g, low-quality protein sources, artificial colors, oversized 1500+ kcal scoops.
