What is a weight gainer?
If you’re looking to gain weight, build strength, or increase size then you’re going to have to consume more calories than you burn throughout the day — known as a calorie surplus.
And, although that sounds really simple, eating the wrong types of foods can lead to an increase in body fat, which isn’t ideal. To gain muscle you must combine a calorie surplus, with high-quality protein sources — which contribute to the growth and maintenance of muscle mass1 — and a well thought-out strength training plan.
We know that getting your nutrition right, when leading an active lifestyle, can be difficult — and that’s where we come in. Our weight-gainer supplements combine high-quality ingredients with ultimate convenience, delivering the fuel you need, wherever you are.
What is Impact Weight Gainer?
This beast of a supplement boasts 31g of protein, a staggering 50g of carbs, and a massive total of 388 calories per serving, setting you up to achieve those all-important gains1 — all while boosting your recovery2 after those high-intensity workouts.

Our Packaging
We’ve gone through an exciting redesign, and as we step into a new era, you’ll see fresh packaging in your orders. Change is a good thing. But change takes time. Especially when you make change responsibly.
Because we don't believe in wasting perfectly good packaging — that would go against our sustainability pledge — you might get a mix of old and new designs inside your orders.
Rest assured, it’s still the same consistently high-quality product, just as you’d expect. If you happen to receive classic packaging, know that your order is helping to reduce waste. And if you receive anything with a fresh look, you’re one of the first, and we'd love to hear what you think.

1.Protein contributes to the growth and maintenance of muscle mass.
2.Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This beneficial effect is obtained with the consumption of carbohydrates, from all sources, at a total intake of 4g per kg body weight, at doses, within the first 4 hours, and no later than 6 hours, following highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.
When to take Impact Weight Gainer?
Add 3 1/3 large scoops (100g) to 500-1000 ml of water or milk, and enjoy first thing in the morning, immediately after exercise, or as a nutritious snack between meals — great for achieving that much-needed calorie surplus.

Gained 1/2 stone in a month
Taking 2 scoops, 3 times a day and going to the gym about 4/5 times a week, I have noticed over a 5kg gain in a little over a month. I'm 6ft4 and have been a relatively slim build all my life. Really pleased with the result of this product; the only draw back is that my farts now peel the paintwork off the walls and my house mates now hate meGoes Well With:A well ventilated environment

Pure beastliness
Been shovelling this down through the first lockdown and now I'm an absolute weapon. The powder is nice and powdery and as far as flavour goes its good enough to eat. It's best to pour a bottle of tequila in with the mix (and a splash of milk) so that your body goes numb and you can't feel pain in the gym. Every rep counts! This is also good because you'll get a good night sleep once blacked out and more sleep means more gains.Goes Well With:High functioning alcoholism

Fantastic
I am recovering from a serious road accident that took place in November 2015. As a result, I am now seriously underweight. I am a small guy (5.6) and at the start of November, I weighed 6.13. This product has helped me gain 6 pounds in a week and is supplying me with the energy to relearn how to walk.Goes Well With:Full Fat Milk

The amount of scoops they say is over 100g which is the serving you are supposed to have
The shake is really good and tastes nice when it it mixed with whole milk but the suggested serving is 100g and they say to put 3 and 1 third scoops into your cup, but I weighed my powder and all I needed was two 70ml scoops and that made the 100g. This will make it last longer and ensure you aren't taking too much powder. Goes Well With:Whole milk (blue lid)

The Best
I truly love this weight gainer. I've always found it hard to put on weight and find it difficult to stomach large meals. Impact Weight Gainer has helped me with my goals of putting on weight. Along with a weight training program, a balanced diet and Impact Weight Gainer I've went from being 9.5st to 12st in 5 months! I find it mixed great with both water and full-fat milk, my recommendation though is to mix with ice cold water if drinking before your going to eat, and with milk at other times as with milk its very filling. 5***** review from meGoes Well With:Milk Ice cold water

Good stuff
Value and effective, I couldn't really care what it tastes like I want cheap and effective, none of this maximuscle bullshit that four times the price and does the same thingGoes Well With:Training like a MF!

New recipe, but who cares
I've had a few versions of this over the years, and this is by far the poorest version in terms of drinkability. It mixes poorly, and given a few minutes it separates. You can be found drinking water and having what looks like wet cement at the bottom. And yes, it's going to make you fat. But.... This is where we have to remember what we are trying to achieve here. This is ALL about weight gain. Keep the water level low, I go 2 scoops and about 400ml water in the morning. Shake hard, and just drink it. In one go. Like a horrible sedimenty medicine. It's really nothing to cry over. This is going to build you up. You wont be so hungry, so try to do it when you have a natural hour between eating. The fat it gives you, well you can burn that off later, it's all fuel. And the extra weight, well that's POWER, so you are going to lift BIGGER. This is going to build you bigger. I shall probably ease off it when the summer hits and shred, but it's still winter bulk and this is great.Goes Well With:Water, 400ml and 2 scoops. Drink fast. I also have Whey Protien during my work out and Overnight recovery before bed (Strawberry Cream is delicious). I'm pretty comfortably doing 5 nights a week in the gym without getting too worn out, I could probably sleep a bit better to overcome that but I like to party too..

Great taste
Bought this for my boyfriend who struggles to put on weight no matter how much he eats. First off, this does not taste like a protein shake and I would honestly mistake it for a chocolate milkshake...it's so nice! He loves it too and is finding it really easy to mix and incorporate into his diet. Can't wait to see the results. Goes Well With:Whole milk

Protein When Needed
This stuff is perfect when needed. 1 scoop or 2 scoops in a shake or as I do, in my bowl of porridge every morning to start the day with 25g + of protein...unflavoured is not a problem as you can add your own... fruit, syrup, honey or banana... it’s up to you....great value too...I prefer the 2.5 kg pouch...it’s a good size for storing and not too bulky.Goes Well With:Porridge, shakes.

Grainy an un-mixable
This product is not nice at all, it’s super grainy and doesn’t mix with milk or water. It taste absolutely disgusting too which is a huge shame because I use to buy from my protein all the time but will definitely not be buying this product again. Goes Well With:Nothing!
