My protein are a supplement company owned by the HUT Group, based in the UK near Manchester. The brand has been going for over ten years now, and has established itself as one of the most well-known and popular Whey Protein and supplement brands in the UK, as well as globally.

I remember when I first started lifting, I’d have to go and meet a haggard old bodybuilder at my local gym down a dark alleyway to buy a tub of CNP Protin powder.

At the time, I thought it was magic. Obviously, there was a 300-pound ripped guy on the front, so I was convinced I’d look like that as long as carried on working out and taking this rank-tasting powder.

How little I knew…

A few years later Argos (a big department store in the UK) started selling Maximuscle Progaiin a tub. This made Whey protein a little easier to buy but the experience wasn’t great.

It was available in Chocolate, Vanilla and Strawberry, all of them overly sweet and lumpier than the custard they used to feed you in school.

Fast forward to now and we’re spoilt for choice in terms of brands, flavours, sizes and types of Whey protein, and for me, My Protein is leading the way.

My Protein Impact Whey

My Protein is definitely more understated than other brands, with minimal, neat packaging that doesn’t promise 20lbs of muscle in 2 weeks, and more flavours than your local Ben ‘n’ Jerrys concession at the cinema.

One of the reasons My Protein is so popular is that it’s competitively priced, probably because it’s sold in bags, not tubs, and is generally only available online, rather than in stores.

How Do The Macros and Micronutrients Stack Up?

This is the number one thing to look out for when buying protein powder.

You obviously have a goal in mind if you’re thinking about buying supplements, so getting something that’s going to help you get to that goal is vital.

Most people in the market for Whey Protein will want to gain muscle or lose fat (or both), My Protein is great for both of these goals, given it’s relatively low in calories and high in protein.

Let’s see how it stacks up per 100g;


And per serving (25g)


The main point to takeaway here is that Impact Whey offers a relatively high amount of protein, for relatively few calories.

You’ll only see that kind of Protein-to-calorie ratio in very lean meat like turkey, or lean fish like Shrimp, Prawns or any White Fish.

So, Impact Whey is excellent for building (or maintaining) muscle tissue, while keeping fat gain to a minimum. Impact Whey is also rich in BCAAS, meaning the protein is high-quality and perfect for stimulating muscle protein synthesis.

Of course, just using protein powder alone won’t make you build muscle or burn fat, but it can be a useful addition to your toolbox when you’re dieting or training to build muscle.

Is Impact Whey Any Good?

Yes, the product itself is high quality, tastes good (depending on the flavour) and is relatively cheap. 

I’ve been using Whey Protein for over ten years, and My Protein Impact Whey is always my go-to staple.

For me, these are the top 3 best things about My Protein Impact Whey;

  1. They’re constantly innovating with new flavours, so each time you come back to the site, there’s something new to try 
  2. While they may not be the #1 cheapest brand on the market, there are ALWAYS offers on, so you can be pretty sure you’ll be able to bag yourself a bargain
  3. It’s available in lots of different sizes. This is great because if I want to try a new flavour, I don’t want to get stuck with a 5kg bag if it tastes like feet. Luckily, My Protein offers 500g bags, so you can try new flavours safe in the knowledge that if you hate it, you haven’t wasted a ton of cash.

The other key thing to note about My Protein is that you can be sure of the quality.

A few years back Labdoor did a mass quality study on various different Whey Protein brands with the aim of investigating the accuracy of the labels (i.e. the protein content) and whether or not they contained any harmful substances.

My Protein Impact Whey received an A+ rating along with only three other brands. It also received a virtually perfect score of 99.9/100 and was found to have almost 100% accuracy with the labelling, and found to contain no Lead, Arsenic, Cadmium or Mercury.

This should also reassure you that Impact Whey is 100% safe.

You can’t say fairer than that…

When you add to this the fact that Impact Whey tastes really good (at least most of the flavours I’ve tried do- and I’ve tried a lot!) and mixes well with no lumps, it’s pretty much unbeatable in my eyes.

Where To Buy My Protein

The best place to buy My Protein is on their own website.

This is the place where you’ll get all the latest vouchers and discount codes (remember to use the Honey plugin in your browser if you want the best deals to be found automatically for you), and where you’ll be able to find ALL of the flavours, as well as all of their other products

There are of course plenty of other places you can buy My Protein online including;

  • Predator Nutrition
  • Dolphin Fitness
  • Holland and Barrat
  • Boots
  • Argos
  • Tesco 
  • Costco
  • Amazon

But I’ve always found that you’re far better off buying directly because you’ll get better prices and more choice. There are of course loads of places to buy My Protein -in-store if you’re that way inclined, but again there’s no way they’ll be able to keep up with all the new flavours that are released seemingly on a monthly basis, and will most likely just stock the standard popular ones (Chocolate, Salted Caramel, etc)


There’s no denying that My Protein is really cheap.

We know it’s not a quality issue, so why is it so cheap?

I don’t actually know, but I would guess it’s party down to the packaging (it comes in a flexible bag rather than a solid tub), and the fact that because the brand is so big, they don’t need to have the exposure in stores, so they can make enough sales purely online.

Anyway, let’s get down to the cost.

The price of Impact Whey does vary slightly depending on the flavour (with unflavoured being the cheapest). But the pricing is generally quite consistent. The biggest price differentiator is the pack-size you buy.

Pricing based on pack size typically looks like this;


(N.B. Not all pack sizes are available for every flavour)

Now that’s just the standard pricing, as I mentioned, My Protein ALWAYS have some kind of promotion going.

For example, right now they’re offering 35% off everything or 40% off a £40 minimum spend, which means that the prices actually work out like this;

SizeCost (After Discount)


So actually, the products are MUCH cheaper than you think at first glance.

Now at the time of writing, there were no voucher codes, but sometimes you’ll get these ‘default discounts’ PLUS some money off using a voucher code.

THIS is why My Protein is so cheap!

Delivery Options

My Protein is based in the UK, but does ship worldwide to over 30 countries including

  • USA
  • France
  • Germany
  • Italy
  • Spain
  • China
  • Japan
  • Australia

The shipping options and time will obviously vary by country and region, but in the UK, if you spend over £60, you get free next-day delivery.

It makes sense to buy in bulk and get free shipping, especially if you make frequent orders.

If you spend less than £60, you can choose one of two options;

Standard Delivery

Standard delivery takes between 2 and 3 days. I’d go for this option unless you’re desperate for whey protein, I find that 9 times out of ten it only takes 2 days anyway

Next Day Delivery

Next-day delivery costs £5.99 and ensures your products are delivered the next working day (so if you order on a Friday, you won’t get your protein until Monday). To get next-day delivery, you need to order before Midnight the previous day.

Payment Options

As well as different delivery options, my Protein offers a range of payment options.

You can pay outright using a credit card, debit card or payment providers like PayPal and Google Pay, but a recent update means you have the choice of several different buy now pay later options including;

  • Klarna
  • SplitIt
  • Vyne
  • Clearpay
  • Humm
  • Trustly

This means that if you’re paying a large lump sum and you want to split it over the course of a few months, you can.

For example, with Klarna, you can pay later (in 30 days) or you can pay in three interest-free instalments.

Something new My Protein now offer is a subscription service. This is where you commit to a regular, recurring order of a particular product, with a discount incentive.

This is definitely worth the investment if you know exactly what you want, and how often you want it, but will probably be a waste of money if you want more flexibility.

Scoop Size

All my Protein products come with a free plastic scoop.

With Impact Whey Protein, the scoop size is 25g, of course if you use a heaped scoop, you’re probably looking at a few extra grams, but for one typical scoop, you’re looking at the following calorie and macronutrient breakdown;


The calorie content and protein content do vary slightly depending on the flavours, but the breakdown above is typical, and any variance is minimal.

My Protein Scoop Size

Size Options

My Protein offers the widest range of sizes on the market.

The best thing about this is, it means Impact Whey suits all budgets and if you want to bulk buy and save money long-term you can.

I personally never buy any larger than 1kg, purely because, no matter how much I enjoy any one flavour, I always get bored of it after a while.

If a new flavour comes out that I like the sound of, I’ll buy the smallest possible bag (250g or 500g), so if it’s unexpectedly disgusting, I don’t need to suffer it for too long, or I can just lob it in the bin and not feel bad that I’ve wasted a ton of money.

Below, you can see that the cost per serving goes down if you choose larger pack sizes.

If you’ve found a flavour that you REALLY love and you know you won’t go off it, then it does make financial sense to buy a 5kg bag.

If you want to save as much money as possible AND experience different flavours, one other thing you could do is buy a bag of unflavoured Impact Whey and buy some Flavdrops

These are liquid flavourings that will transform the taste of your protein and allow you to experience a different flavour each time.

What’s The Best My Protein Flavour?

This is of course totally subjective, but having tried over 50 different flavours, I can definitely tell you what I prefer.

My personal number one favourite is Chocolate Mint, but then I love chocolate mint in general, if you don’t like Aeros and After Eights, you probably won’t like it!

Here are my top 10 favourite flavours in descending order;

  1. Chocolate Mint
  2. Cereal Milk
  3. Dark Chocolate
  4. Blueberry Cheesecake
  5. Cherry Yogurt
  6. Coconut
  7. Chocolate Coconut
  8. Cinnamon Danish
  9. White Chocolate
  10. Chocolate Brownie

Most people prefer either fruity flavours (Strawberry, Blueberry, etc) or chocolate-based flavours. If you’re a chocolate lover then you’re in luck because there are no less than 12 chocolate flavours available.

Impact Whey Isolate vs Impact Whey Concentrate

There are lots of different styles of protein, but Whey Concentrate and Whey Isolate are probably the two most common.

While they are fairly similar and won’t really make a huge amount of difference for the average person, there are a few key differences to highlight.

First of all, Whey Isolate is much more suitable for those with lactose intolerance, since all of the lactose is essentially ‘broken down’. This makes it much easier to digest and means it won’t cause any issues with bloating.

Second, Whey Isolate is lower in fat and carbs than Why Concentrate, this means that its lower in calories, and has a higher percentage of protein.

Isolate also has a much finer texture; think sand vs pebbles (not literally), once mixed, this gives it a ‘thinner’ consistency and is, therefore, a bit more watery and less ‘milkshake-like’

Finally Isolate is more expensive than Whey. Here’s a comparison so you can quickly see the (albeit negligible) differences.

Impact Whey Isolate vs Impact Whey Concentrate

Impact Whey Concentrate Impact Whey Isolate
Cost (per 1kg)£39.99£55.99
Calories (per 100g)394359
Protein (per 100g)77g81g
Carbs (per 100g)7.8g4.6g
Fat (per 100g)6.2g1.1g

So is Whey Isolate worth it?

While it might be technically optimal, and maybe the one to go for if you have an unlimited budget, or if you suffer from Lactose intolerance, the slightly higher protein and slightly lower calories aren’t worth the extra cost.


Is Impact Whey Good for Building Muscle?

Yes. Protein is important for building muscle, and protein shakes like My Protein Impact Whey is one of the easiest. Cheapest ways to get more protein in your diet.

You should be aiming to consume around 0.8g of protein per pound of body weight.

Of course, the main determining factor in whether or not you’ll build muscle is your training program. You’ll need to be regularly and intensely training the muscle groups you want to build, and making sure you’re applying progressive overload to those muscles.

No amount of protein will help you build muscle if you’re not training effectively.

When Should I Drink Impact Whey Protein?

Honesty, it doesn’t matter.

With protein, the main thing you should be concerned about is how much you’re getting per day. As stated above, you should be aiming for about 0.8g of protein per pound of body weight per day.

That means if you weigh 200lb, you should be aiming for 160g of protein per day. You should also look to split that up over regular feedings throughout the day (3-5 feedings), this will helps stimulate MPS (Muscle Protein Synthesis), which is the process of converting protein into muscle tissue.

For example, if you had 4 feedings, that’s 40g of protein per meal.

Does drinking protein directly after your workout have any impact on muscle building? It’s highly unlikely, so don’t worry about chugging down a shake seconds after you’ve done your last rep in the gym.

What Happens if You Drink Impact Whey every day?

Nothing. Impact whey is perfectly safe to consume on a daily basis.

But remember, it is a supplement, not real food, so the majority of your protein should be coming from whole food sources like meat, poultry, fish, dairy and eggs.
