How much does a mass gainer cost in Thailand?

Genuine gainers at UnReal Supplements in Bangkok range from ฿1,570 (Rule1 Mass Gainer 6 lb) to ฿3,600 (ON Serious Mass 12 lb). Dymatize Super Mass is ฿2,140 for 6 lb and ฿3,240 for 12 lb, roughly ฿160 to ฿270 per full serving.

Which mass gainer is best in Thailand?

For pure value, Rule1 Mass Gainer at ฿1,570 per 6 lb is the cheapest genuine entry. Dymatize Super Mass (฿2,140 per 6 lb) offers about 1,280 calories and 52 g of protein per serving, and ON Serious Mass (฿2,000 per 6 lb) is the classic high-calorie option at about 1,250 calories. The best one is the one you will drink consistently.

Do mass gainers actually work?

Yes, if your problem is calories. A gainer is protein plus a large dose of carbohydrates, and a consistent calorie surplus plus training is what builds size. If you already eat enough, a gainer adds mostly fat, so fix food first and use the shake to fill the remaining gap.

Mass gainer or whey protein, which should I buy first?

Buy whey if you need more protein, a gainer if you need more total calories. Most people do better with whey plus calorie-dense food, which is cheaper per calorie. Hard gainers who genuinely cannot eat enough are the ones a gainer is made for.

How do I take a mass gainer?

Mix half to a full serving with water or milk, between meals or after training. Half servings digest more easily and still add 600+ calories. Aim for a surplus that adds roughly 0.25 to 0.5 kg of bodyweight per week, and keep protein at 1.6 to 2.2 g per kg per day from all sources.

Mass gainer in Thailand: what to buy and what it costs

A mass gainer is protein plus a large dose of carbs and calories for people who cannot eat enough to grow. In Thailand, genuine gainers at UnReal Supplements in Bangkok cost from ฿1,570 for a 6 lb Rule1 Mass Gainer to ฿3,240 for a 12 lb Dymatize Super Mass, roughly ฿160 to ฿270 per serving. If you can hit your calorie target with food, skip the gainer and buy whey instead.

Who actually needs a mass gainer

A mass gainer is a convenience food: a shake of protein plus a few hundred grams of carbohydrate, delivering 1,000 or more calories in a form that is easy to get down. It exists for one type of person, the hard gainer who trains hard, eats what feels like a lot, and still cannot push bodyweight up.

If you gain weight easily, a gainer will mostly add fat. If you can hit a calorie surplus with rice, eggs, milk and oats, food is cheaper and more nutritious. The gainer earns its place when chewing another meal is genuinely the bottleneck, or when you need calories you can drink between work and training.

Mass gainer prices in Thailand, 2026

At UnReal Supplements in Bangkok, current Thai Baht prices for genuine gainers: Rule1 Mass Gainer 6 lb at ฿1,570 and 12 lb at ฿2,550. ON Serious Mass 6 lb at ฿2,000 and 12 lb at ฿3,600, in Chocolate and Vanilla. Dymatize Super Mass 6 lb at ฿2,140 and 12 lb at ฿3,240 in Rich Chocolate. Ultimate Nutrition Muscle Juice 11 lb at ฿2,940 in Chocolate, Vanilla and Strawberry, and IA Hard Mass Gainer 12 lb at ฿1,789 as the budget bulk option.

Per serving, the big tubs win again. A 6 lb tub is roughly 8 to 10 full servings, so Rule1 works out to about ฿160 to ฿200 per serving, Serious Mass around ฿250, and Super Mass around ฿270. The 12 lb tubs cut that meaningfully, which is why consistent users buy big.

What you get per serving

The big three all sit in the same territory: Dymatize Super Mass delivers about 1,280 calories and 52 g of protein per full serving, ON Serious Mass about 1,250 calories and 50 g of protein, and Rule1 Mass Gainer about 1,220 calories and 40 g of protein. The differences are in carb sources, sugar content and taste, not in whether they work.

A practical tip: the label serving is huge, often four scoops. Half servings are easier on the stomach, mix better, and let a tub stretch twice as far while still adding 600 or more calories to your day.

How to use a gainer without getting fat

Fill a real gap: use the shake to close the distance between what you eat and your calorie target, not on top of an already full diet.
Time it around training or between meals, when a liquid 600 to 1,200 calories is easiest to absorb.
Start with half servings to test digestion, then scale up.
Keep daily protein at roughly 1.6 to 2.2 g per kg of bodyweight from all sources; the gainer contributes to that total.
Track bodyweight weekly. If you are gaining much faster than about 0.25 to 0.5 kg per week, pull calories back.

Gainer or whey: which should you buy?

If your problem is protein, buy whey. If your problem is total calories, buy a gainer. Many lifters do best with whey plus cheap food carbs like rice, bananas and oats, which costs less per calorie than any gainer. The gainer is the answer when convenience is the deciding factor.

Budget comparison: a 5 lb whey tub at UnReal costs ฿1,879 to ฿3,710 depending on brand, while a 12 lb gainer costs ฿1,789 to ฿3,600. Per gram of protein whey wins easily; per calorie the gainer wins. Buy for the gap you actually have.
