Best Mass Gainers 2026: Complete Ranking

Buying a mass gainer in Estonia goes wrong the same way almost every time. Someone reads an international top-10 list, picks a product that is not sold here, orders something random as a substitute, and discovers a month later that they bought a powder carrying thirty grams of sugar per 100 grams and a solid case of bloating.

This guide is built the other way around. We start from what is actually on the shelf in Estonia, what it costs per kilogram, and whether you need it at all. Every price below was valid at the time of writing and prices move, so always check the product page before buying.

The short answer, if you do not want to read further: a mass gainer is a convenient and fairly expensive way to eat oats, milk and whey protein. It pays for itself only when your real bottleneck is eating, not training. If you can already hit your calories from food, this is money thrown away.

What is actually inside a mass gainer

Most weight-gain blends are a mix of three components. The protein part is usually whey concentrate, often blended with casein so digestion does not run too fast. The carbohydrate part is maltodextrin, oat flour, tapioca starch, or a combination. The fat part is modest: coconut MCT, flaxseed powder, or powdered sunflower oil. On top of that most products add a vitamin and mineral blend, and some add creatine.

In substance, this is food turned into powder. The mechanism by which a mass gainer works at all is extra calories: a modest energy surplus makes gaining muscle easier, though it is not strictly required - hypertrophy has been documented at energy balance and even in a deficit, and a modest surplus is most likely to be an advantage for an already-trained lifter (Slater et al., 2019). Protein supplementation in turn improves the muscle and strength gains from resistance training, but the effect is moderate and shrinks once daily protein intake is already adequate (Morton et al., 2018).

Two things follow that most ranking articles never say out loud. First: a mass gainer does nothing that oats, milk and ordinary protein powder would not do. Second: it does it faster and without washing up, and if that is your bottleneck it is worth the money. The entire brand argument is a detail next to that.

The three numbers that decide everything

When you read a gainer label there are only three numbers that determine whether the product suits you.

Calories per serving. This is the biggest trick in the whole category. When a tub says 1250 kcal per serving, that serving is usually around 330 grams of powder, meaning four heaped scoops mixed into half a litre of milk. Very few people drink that day after day. An honest comparison uses calories per 100 grams, not per serving: most gainers land between 370 and 400 kcal per 100 grams, and the differences between brands come down to single percentage points.

So that the rest of the arithmetic is unambiguous, we fix one size here. In this guide the word serving always means 100 grams of powder, which is about 390 kcal - exactly a tenth of a kilo, and a kilo yields roughly 3900 kcal. The dose printed on the manufacturer's label is more than three times that, and we do not use it as a protocol. Every number below - the daily surplus, the price per calorie, and how long a tub lasts - refers to that 100 gram serving.

Protein per serving and protein share. A serious blend gives 20 to 25 grams of protein per 100 grams of powder. If that number is under fifteen, you are essentially paying protein prices for maltodextrin. The daily protein target for a lifter is roughly 1.4 to 2.0 grams per kilogram of body weight (Jager et al., 2017), and a gainer should help you reach it, not dilute it.

Sugar. In the Estonian range this is the clearest separator, because cheaper blends carry the flavour on sugar while pricier ones carry it on maltodextrin. An honest line is about fifteen grams of sugar per 100 grams of powder. In products packing thirty grams of sugar per 100 grams, the problem is not the sugar itself but that you are paying protein-blend money for it.

How fast it makes sense to gain

This is where most people make the decision that costs them three months of dieting later. A bulk is not a speed, it is a pace.

In an intervention study on elite athletes, those who gained weight slowly with a controlled surplus built as much lean mass as the fast gainers but put on significantly less fat (Garthe et al., 2013). In practice that means about 0.25 to 0.5 percent of body weight per week. For an eighty-kilogram lifter that is 200 to 400 grams a week, not a kilo.

Turn that into calories, because this is exactly where most plans break. Roughly 7000 kcal go into every kilogram of gained tissue, so 200 to 400 grams a week means a surplus of 1400 to 2800 kcal a week, which is 200 to 400 kcal a day. A 100 gram serving delivers about 390 kcal, so mixed with water one serving a day lands almost exactly on the top of that band. That is why the protocol below is one 100 gram serving a day, and no more.

And that is why the dose printed on the label is not a protocol. A 1250 kcal daily surplus works out at roughly 8750 kcal a week, or close to 1.25 kg - three times over a sensible ceiling, and mostly fat. Even two 100 gram servings a day come to 780 kcal, about 780 grams a week, still twice too fast. That is the level at which most people gain mainly fat and then wonder, three months later, why their waist changed and their shoulders did not.

A practical check: weigh yourself in the morning three times a week, take the weekly average, and compare it with the previous week. A single weigh-in tells you nothing, because a salty dinner or training-induced fluid retention moves the scale by a kilo and a half.

Carbohydrate source: maltodextrin, oats, or both

Maltodextrin has become an internet trigger word. The reality is duller. Maltodextrin is a rapidly absorbed carbohydrate derived from starch, with a high glycaemic index; it dissolves well and it is cheap. That is exactly why it is a reasonable choice after hard training or between two sessions, since it refills glycogen quickly and does not sit heavy in the stomach (Kerksick et al., 2018).

The same ingredient is a poor choice when you drink it on the sofa two hours before bed. A carbohydrate is not good or bad as a property living inside the tub; it depends on context. Oat-based blends absorb more slowly, carry more fibre, and keep you full longer, which is better between meals and not better in the post-training window.

If the topic interests you in more depth, we have written it up separately: maltodextrin in sport - when it really works and when it does not.

Practical advice: if you are only going to own one tub, pick a blend that carries both a fast and a slow carbohydrate. If you train early in the morning or late at night and your meals are already frequent, lean towards oats.

What is actually available in Estonia

This is where the international ranking and the Estonian reality part company. A large share of the products that English-language lists put at the top never arrive here, or arrive at a price that makes the whole calculation pointless. So we only look at what you can actually buy locally. The full selection sits in the mass gainers category.

The cheapest entry ticket by sticker price is ICONFIT Mass Gainer 1.5kg Vanill, which cost 19.90 EUR at the time of writing. At one serving a day a kilo and a half is fifteen days: enough of a tub to test properly, but not so large that months of the wrong flavour end up in the cupboard. If you have never used a gainer before, that is a smarter start than a three-kilogram bag.

An even smaller risk is BIOTECHUSA Hyper Mass 5000 1kg Šokolaad at 21.90 EUR at the time of writing. Per kilogram it is the most expensive option on this list, but it is also the smallest pack here: at one serving a day you finish it in ten days and can then make an informed decision. Taste and digestive tolerance are the two things you cannot read off a label, and ten days is the cheapest way to find out.

In the middle of the price range sits Mutant Mass 2.27kg Šokolaadibrownie at 34.90 EUR. It has a distinctly sweeter profile, it is calorie dense and it is easy to drink, which is a plus for anyone whose actual problem is a missing appetite.

The classic is Optimum Nutrition Serious Mass 2.73kg Šokolaadi-maapähklivõi at 47.90 EUR. Serious Mass has been a volume seller in this category for nearly two decades and the reason is simple: the dose on the label is enormous and the calories add up fast. That same reason is its biggest drawback, because that dose is so large that most people use a third or a half of it, which changes the whole price calculation.

None of those wins on price per kilogram, though. That slot goes to Mutant Mass Extreme 2500 Vaniljejäätis 5.4kg, which cost 58.90 EUR at the time of writing. It carries the highest sticker price on the list, but 5.4 kg works out at roughly 10.90 EUR per kilo, close to a fifth cheaper than the ICONFIT most people buy precisely because it looks cheap. The trade-off is obvious: it is also the one pack where the wrong flavour means nearly six kilograms of regret, so a 5.4 kg tub is not a first purchase until you know the taste and your stomach agree with it.

Sharing the price bracket with the three-kilogram bags is Dymatize Super Mass Gainer 2.943kg Šokolaad, which cost 49.90 EUR at the time of writing. Just under three kilograms, roughly 16.95 EUR per kilo - essentially the same slot in the table as the MST and the DY, with a better-known label on it.

Always check the current price on the product page, because prices move.

The price that matters is per 1000 kcal, not per tub

The sticker price is a misleading number, because pack sizes differ and the servings manufacturers recommend differ even more. The only comparison that says anything is price per kilogram, and from there price per 1000 kcal.

Since gainers typically land between 370 and 400 kcal per 100 grams, one kilogram yields roughly 3900 kcal. That gives a simple rule of thumb: divide the price per kilo by four and you have the approximate price per 1000 kcal.

Below are all the same products as in the table above - no row has been dropped, because the worst-value rows are exactly the ones worth seeing. The order runs from the cheapest calorie to the most expensive.

The two ends of that table say more than any ranking position. The cheapest calories belong to Mutant Mass Extreme 2500 Vaniljejäätis 5.4kg at roughly 2.80 EUR per 1000 kcal, exactly half the price of the bottom row. The most expensive calories sit in BIOTECHUSA Hyper Mass 5000 1kg Šokolaad and SELF Mass Active Gainer 2kg Piimašokolaad, and each has a reason: with the first you are paying for the small pack, with the second for a higher-protein, lower-carbohydrate formula. If price per calorie is your only criterion, the top of the table is where to look. If you are not yet sure the flavour and your digestion agree with you, the bottom of the table is the cheaper mistake to make.

For comparison: a kilogram of oat flakes yields about 3800 kcal and costs a fraction of that in any Estonian grocery store. That does not make a gainer a bad purchase; it means you are paying for the protein, the convenience and the flavour, not for the calories. If your only goal is calories, oats are cheaper. If your goal is calories plus 20 grams of protein with no cooking involved, the maths is different.

Who should skip a mass gainer

This is the section most ranking articles cheerfully leave out, because it reduces sales.

A gainer is not for you if you already hit your calorie target from food. In that case it adds nothing but cost and half-used tubs in the cupboard. It is also not for you if your actual goal is fat loss and you are hoping a calorie-dense powder will somehow make you leaner, because an energy surplus always adds some fat mass and the only question is how much (Garthe et al., 2013).

It does not suit people whose gut objects to a large carbohydrate load in one hit. That is more common than people admit and shows up as bloating and discomfort an hour and a half after drinking. In that case the cleaner solution is a separate protein powder with calories from real food, because then you control the two variables independently.

And it does not suit anyone buying it to paper over smaller problems. If you sleep five hours a night, train twice a month and eat irregularly, no powder changes that. If you have dietary restrictions from a health condition or you are on a course of medication, the right address is your doctor or a dietitian, not a product page.

The homemade alternative, which costs less

If you want to see what you are actually paying for, make the blend yourself once. One blender jug gives you:

• 100 g oat flakes: about 370 kcal and 13 g protein
• 400 ml whole milk: about 260 kcal and 13 g protein
• 1 medium banana: about 105 kcal
• 30 g peanut butter: about 180 kcal and 7 g protein
• 30 g whey protein powder: about 120 kcal and 24 g protein

That is roughly 1035 kcal and 57 g of protein. It is essentially the same profile as a large share of commercial gainers, and the ingredient list fits in one glance. The downside is obvious: it needs a blender, a fridge and two minutes you do not have in a gym changing room.

Next to that, the real added value of a commercial gainer is convenience and portability, not biochemistry. The honest way to save money is to use the homemade version at home and keep the powder for the times you cannot reach a kitchen.

A practical protocol

Week one: half a serving a day, meaning 50 grams of powder and about 195 kcal. Not because a full one is dangerous, but because for most people even that is plenty the first time, and digestive tolerance decides whether the tub gets finished or gathers dust.

From week two: one full serving a day, meaning 100 grams of powder and about 390 kcal, split into two 50 gram halves if needed. No more than that, and more is not better: 390 kcal a day is the surplus that produces 0.25 to 0.5 percent of body weight a week. Two halves across the day are almost always more tolerable than one large drink.

Water or milk. A 100 gram serving needs about 300 ml of liquid. Water keeps the drink light and quick to digest and leaves the daily surplus at 390 kcal. Milk improves the texture, but 300 ml of whole milk adds another 195 kcal and 10 g of protein, taking the serving to 585 kcal - already over the target band, so subtract the milk from the rest of the day. If your problem is a missing appetite, use water. If your problem is calories and you otherwise eat little, use milk.

Timing. The post-training window is the most sensible slot, because fast carbohydrates fit well there and appetite is usually low right then. The second good slot is breakfast, for people who cannot face food in the morning. Straight before training is a bad time: a hundred grams of powder and three hundred millilitres of liquid in the stomach improve nobody's squat sets.

Mixing. Always pour the liquid in first and the powder on top. In the reverse order the powder cakes on the bottom and the shake comes out lumpy. A 100 gram serving fits an ordinary shaker without trouble. The 330 gram dose printed on the label does not, which is one more reason it does not work in practice: that one is a blender job.

What to add and what not to

Creatine monohydrate is the one supplement that genuinely belongs alongside a gainer. It is well studied, cheap, and it works in exactly the same context: resistance training where the goal is more reps and more load (Kreider et al., 2017). Three to five grams a day, every day, rest days included. Some gainers already contain creatine, but often below an effective dose, so check the label. The selection is in the creatine category, and we have written it up in detail in the creatine guide.

What you do not need to add: a separate carbohydrate powder, since that is already the main component in the tub; a fat burner at the same time, because the two goals work against each other; and another sweet milk drink on top of the day. Testosterone-boosting supplements are heavily marketed in this category and the evidence for them is thin, so treat them as a last step, not a first one.

The Estonian context: why a gainer makes sense here at all

The Estonian training year is seasonal. Gyms fill up in October and empty in May, and the so-called bulking season lines up almost exactly with the dark half of the year. That is not a coincidence: appetite is bigger in the cold and beach season feels far away.

There is a flip side. From November to March daylight is scarce, sleep drifts, and for many people the regular eating routine disappears. A gainer is genuinely a useful tool in that stretch, but for exactly the same reason it is easy to overdo, because when calories are easy to get and summer feels distant, weight climbs faster than planned. If you start in October, set a target pace and weigh yourself, or April is an unpleasant surprise.

The practical side: most gyms here let you bring a shaker into the hall and hot drinks are generally not allowed, so mixing happens with cold liquid in the changing room. If you are looking for somewhere to actually use it, we have reviewed the gyms separately: the best gyms in Tallinn.

The summary in three sentences

If you can eat enough from food, you do not need a gainer. If you cannot, choose a blend by three numbers per 100 grams - calories, protein and sugar - and calculate the price per kilogram rather than per tub. Start with a smaller tub, keep weekly gain at 0.25 to 0.5 percent of body weight, and weigh yourself regularly, because that is exactly where most plans fall apart.

FAQ

Does a mass gainer make you fat?

A calorie surplus makes you fat, not a specific product. A gainer makes creating that surplus easy, which is the entire point, and precisely why it is easy to go past a sensible line. Keep weekly gain at 0.25 to 0.5 percent of body weight and the fat share stays small (Garthe et al., 2013).

Do I need to take it on rest days too?

Yes, if the goal is weight gain. Muscle does not grow during training but between sessions, and the calorie target is weekly, not daily. On a rest day you can move the serving to the morning or between meals.

Is a gainer suitable for women?

The product is not gender-specific. The contents are protein, carbohydrate and fat. The only question is the calorie load: if your daily requirement is lower, half a serving - 50 grams and about 195 kcal - is usually the right amount rather than a full one.

Why does my stomach object to gainers?

The most common reason is the amount in one hit: the 330 gram dose printed on the label is a full meal, not a drink. The second common reason is lactose in whey concentrate. Try half a serving, 50 grams, mix it with water instead of milk, and split it across two doses a day. If that does not help, a separate protein powder plus real food is the cleaner solution.

Is a cheaper gainer worse?

Not automatically. Compare three numbers per 100 grams: calories, protein and sugar. If the cheaper product has 20 g of protein and under 15 g of sugar per 100 grams, it is not worse than the expensive one, it is just less marketed. The biggest real difference between price tiers is flavour and mixability, not effect.

How long should one tub last?

Work it out yourself: divide the pack weight by the serving size. At one 100 gram serving a day a 1 kg tub lasts ten days, a 1.5 kg tub fifteen, a 2.27 kg tub about 23, a 3 kg bag thirty, and a 5.4 kg pack close to two months. If a tub runs out faster than that, your servings have crept up without you noticing, which is the most common reason weight climbs faster than planned.
