  • Product Overview

    Impact Weight Gainer | Product Overview & Benefits

    Our Impact Weight Gainer is a beast of a supplement, perfect for anyone wanting to increase size and mass. Your body can only do this if it’s in a calorie surplus – simply put, you have to consume more calories than you burn.

    Need to rack up the calories? This protein and carbohydrate powder blend is the one for rapidly increasing your daily count.

    What are the benefits of Impact Weight Gainer?

    Our new formulation contains over 30g of both fast and slowly digested proteins per serving, making it perfect for post-exercise recovery and for continual delivery throughout the day. This won’t just spike your protein uptake, but will sustain it.

    There’s also 50g of carbohydrates per serving, from oat flour and maltodextrin, giving your body a generous helping of calories, as well as fibre which supports a healthy diet.

    Choose from three classic, delicious flavours – indulgent Chocolate Smooth, creamy Vanilla or sweet Strawberry.

    When should you take Impact Weight Gainer?

    Enjoy your favourite flavour first thing in the morning or immediately pre/post-workout to get the best results.

    Impact Weight Gainer is also ideal for post-recovery as it’s high protein content contributes to the growth and maintenance of muscle mass.

    For even better results, try it with…

    Egg Yolk Powder – prepared from fresh egg yolk, the ideal supplement to add valuable calories and body weight, great for cooking, baking or adding to a shake.

Like drinking flour

I ordered this as an alternative to Hard Gainer Extreme which was out of stock at the time. Bad move, Impact Weight Gainer is no comparison and the taste is awful, like drinking flour.

Impact weight gainer

Great product, excellent value, does exactly what it says on the tin!

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 me
Goes Well With:
Milk Ice cold water


This product is exactly what you need to pack on some serious pounds without losing serious pounds from your wallet! I find for best taste and mixability use with 1/3 boiling water, 2/3 milk. It may leave you with a warm milkshake but it'll definitely leave you with a hotter body!
Goes Well With:
Water and Milk

Great gainer

All round good gainer for getting extra calories in.
Goes Well With:

Thic + sweet

Blend together with almond UHT milk get smooth consistency, best served when chilled. Premix and bottle in portion sized milk bottles with UHT.
Goes Well With:
Almond milk unsweetened

Good price

Strawberry taste is very nice, however isnt great for gaining weight but has good amounts of protein for recovery
Goes Well With:

Very good

Switched to this from using Progain post workout. I find that 3 scoops with 500ml is still not an enjoyable experience as it is so chemically sweet. It gets job done and is affordable so it’s worth buying.

It is what it says

Not going to lie, it isn’t the most enjoyable experience drinking it, BUT don’t let that get in the way. the taste is alright tbh, I bought chocolate and it tastes right, the mix-ability is rough, takes a good shake for a fair while but it’s expected with a 3 scoops (wish it was more concentrated so it would just be a single scoop mix) effectiveness seems to be good so far, it feels like a meal in your stomach which makes it feel worth while. Overall it is a decent product, yes it isn’t the easiest thing to throw down you but not all supplements are going to be. No Pain No Gain as they say.
Goes Well With:
I mix with Creatine to get it all down together.
