Best Mass Gainer Supplements in Singapore (2026)

Mass gainers are high-calorie protein supplements designed specifically for hardgainers and athletes who struggle to consume enough calories from whole food alone. The best mass gainers in Singapore in 2026 deliver 600–1,200 calories per serving with a 2:1–4:1 carbohydrate-to-protein ratio, using clean carbohydrate sources to fuel muscle glycogen without excessive fat gain.

The Complete Guide to Mass Gainers in Singapore (2026)

For the classic Singapore hardgainer — naturally lean, high metabolism, struggles to eat enough — mass gainers are often the missing piece. A well-chosen mass gainer bridges the caloric gap between what you eat and what you need to grow, without forcing down 6 meals a day. Here's how to choose the right one for your goals.

What to Look For in a Mass Gainer

> ⯈ Protein Source Quality: Look for whey concentrate, isolate, or a blend as the primary protein. Avoid products where soy is listed first — it's a cheaper filler with lower anabolic impact.
> ⯈ Calorie Density vs. Your Deficit: Work out how many extra calories you need per day to gain 0.5kg per week (roughly 500 kcal surplus). Choose a gainer that fills that gap — not necessarily the highest calorie option.
> ⯈ Carbohydrate Sources: Premium gainers use oat flour, maltodextrin, or waxy maize — slow-to-medium release carbs that fuel muscle glycogen. Avoid gainers where the primary carb is pure sugar (sucrose, glucose).
> ⯈ Protein Per Serving: A good mass gainer delivers at least 25–50g of protein per serving alongside the calories. If the protein is under 25g per serving, it's not a proper muscle-building gainer — it's a calorie shake.

Mass Gainer vs. Whey Protein vs. Weight Gainer — What's the Difference?

Feature	Mass Gainer	Whey Protein	Weight Gainer (High Carb)
Calories per Serving	600–900 kcal	100–160 kcal	900–1,500 kcal
Protein per Serving	25–60g	20–30g	15–30g
Carb:Protein Ratio	2:1 – 3:1	~1:3	4:1 – 6:1
Best For	Lean bulk, hardgainers	Hitting protein targets	Very fast mass gain, ectomorphs
Risk of Fat Gain	Low–Medium	Very Low	Medium–High

Curator's Note by Allen Pham

"Most Singaporeans don't need a 1,200-calorie mass gainer — they need to be more consistent with their meals. But for true hardgainers who genuinely can't eat enough, a mass gainer as a 4th meal is a game-changer. My recommendation: Mutant Mass for the best calorie-to-protein balance at a fair price. If you want a leaner bulk with more protein control, use BSN True-Mass mixed at a lighter serving size."
