PRODUCT LABEL

NutraBio Extreme Mass

660 calories per four-scoop serving with 53 grams of protein, 101g of carbohydrate and just 7 grams of sugar. Fully disclosed label, no proprietary blends.

The ratio is what makes this different

Most gainers run 3:1 or wider on carbohydrate to protein. Extreme Mass is roughly 2:1 — 101g of carbs to 53g of protein.

Extreme Mass	53g protein / 101g carbs	~2:1
R1 Clean Gainer	30g / 99g	3:1
ALLMAX QuickMass	64g / 171g	3:1

Why that matters: if you are struggling to gain, you usually need both calories and protein — but protein is the harder one to eat enough of, and it is the nutrient that determines whether the weight you gain is muscle rather than fat.

53g in one drink is a very large protein dose, comparable to two standard shakes. For someone genuinely struggling to hit both calorie and protein targets, that is the most useful thing a gainer can do.

7 grams of sugar in 101 grams of carbohydrate

This is the number that justifies calling it clean.

Mass gainers have a deserved reputation for being sugar delivery systems — many hit their calorie targets with cheap sugars, which is why people associate them with fat gain and feeling unwell afterwards.

7g of sugar across 101g of carbohydrate is genuinely low, and there is 5g of fibre alongside it, which most gainers omit entirely.

You do not have to take four scoops

The 660-calorie figure is a four-scoop serving. Every increment below that is a valid serving.

2 scoops	~330 cal, ~27g protein	A sensible daily top-up
3 scoops	~495 cal, ~40g protein	Between meals
4 scoops	660 cal, 53g protein	Full serving

Start at two. A 660-calorie drink is a lot to get through, and people routinely buy a large gainer, find one serving uncomfortable, and abandon the tub. Build a surplus you can sustain rather than one that puts you off.

⚠ One number worth knowing

115mg of cholesterol at 38% of the daily value in a four-scoop serving. That is high for a powder, and worth knowing if you monitor cardiovascular markers. At two scoops it halves.

Saturated fat is 4g of the 6g total, which is modest for the calorie count.

The honest conversation about gainers

We would rather have this with you than sell you something you do not need.

A gainer is a convenience product, not a magic one. 660 calories is 660 calories whether it comes from this or from oats, milk, peanut butter and a scoop of protein. You can build the equivalent from food for less money.

What a gainer genuinely solves is appetite. If eating enough is a real struggle for you — and that is a genuine physiological problem, not a discipline failure — drinking 660 calories is far easier than chewing them. That is the entire case for the product, and it is a good one for the people it applies to.

If your appetite is fine and you are simply not eating enough, eat more food first. It is cheaper and more nutritious. And if you are not gaining, the answer is almost always that total daily calories are still too low — not that you need a different gainer.
