Best Mass Weight Gainer Supplement UK – [Top 9 Reviewed]

Looking in the popular press, you’d be forgiven for thinking that everybody on planet earth is on a quick mission to lose weight. (Hulk Voice) ‘Punt humans, I’ve come to Smashhhhhh!!!

While it’s probably fair to say that obesity is one of the biggest health issues facing the world today, there are still plenty of people out there who are actually looking to put on weight in a healthy way, for many reasons, and not just to look like the Hulk and go human smashing 🙂

We here at DHC have got you back as always! So forget them stick insects in the press.

Here are some of the best tips for gaining weight in a healthy way along with our Best Weight Gainer Supplement UK review.

What to save a few £££? Why not make your own weight gain – MUST READ guide

Quick Jump

Get SMART.  It may be a management cliche but specific, measurable and realistic targets are crucial to achieving any goal.

Your aim is to push yourself as hard as you safely and reasonably can, while still being realistic about the fact that you need time on your side too.

Actually, measure your progress.  What generally happens in any weight-gain process is that change happens a little at a time and may go unnoticed unless you take the time to check.

Put on mass the right way – Don’t be this guy!

Try to find an accountability partner.  This may sound like another management cliche but it genuinely does help a lot of people.

Share your goals with someone you trust and respect and listen to them.

It’s great if they can join you in your journey, e.g. by working out with you, but just having someone to be there for you can really make a huge difference to your chances of success.

As you train, your muscles will keep adapting to the exercises you use, so keep changing them to keep your muscles paying attention.

Rest and sleep are vital.  Your muscles and your mind both need downtime to repair and regenerate themselves.

Eat the right food at the right times.  This may mean adjusting your meals between training and non-training days.

On the subject of eating the right food, mass gainers are designed to provide the nourishment you need in a convenient package.

As with just about any popular product, they vary widely in quality.

With that in mind, we’ve rounded up our top ten list of the best mass and weight gainers.

CNP Professional Pro Mass

Best Weight Gainer For Skinny Guys

The exact nutritional values of this product depend on the specific flavour and how you use it, but all deliver at least 35g of protein.  CNP recommends that users consume either 100g in water or 50g in skimmed milk, the latter of which adds an extra element of protein.

In both cases, most of the protein comes from whey, specifically whey concentrate, but there is also a small quantity of micellar casein.  Regardless of which method you use, each serving also contains about 50g of carbohydrate and in the region of 380 calories.

Pro Mass is on the lighter side compared to some of the products on this list, but we think it’s good that users have choice.  Some people will only want to bulk up a little and hence this product could be far better suited to their needs than heavier-duty options.

Available flavours are: vanilla, banana, chocolate and strawberry.

Verdict – This is a niche product, but could be just what you need if all you want to do is put on a little extra mass.

Mutant Mass

Mutant Mass

Mutant have a fun and quirky image, but they produce some serious health and fitness products and Mass certainly lives up to their high standards.

Servings are 260g of powder, which can be mixed with water or milk, the latter adding extra protein.

The exact nutritional value depends on your flavour and mixer, but is in the region of 50g protein, derived from whey, casein and egg, plus 180g carbohydrates and 1000 calories.

There’s also an impressive 34 g BCAAs, EAAs, glutamine & glutamine precursors & arginine.  Here’s the really good news, Mutant takes taste seriously and so the available flavours are pretty impressive.  They are: cookies & cream, strawberry banana, chocolate, vanilla, chocolate hazelnut and peanut butter chocolate.

In case you thought we’d missed a comma, no, “strawberry banana” is a single flavour.

We have to say that some users report that this brand is strong enough to generate quite a bit of gas, hence users may wish to look at taking a digestive enzyme as well to deal with this potential issue.

Verdict – Let’s be honest, while performance is important, it’s nice to have a product with a decent taste and Mutant Mass is way ahead of the competition in the range on offer.  It’s also has a lot to offer in terms of helping users put on lean muscle.

MyProtein Hard Gainer Extreme

MyProtein Hard Gainer Extreme

MyProtein has built its brand on being the affordable option for people who want decent results at a reasonable price and Hard Gainer Extreme fits this template nicely.

Each 125g serving provides 35g of protein, which is mainly a combination of whey protein (concentrate and isolate) and casein.  It also contains 62g of carbohydrates and 502 calories, plus a whole range of vitamins and minerals and 5g each of L Glutamine and Creatine Monohydrate.

MyProtein is another brand which takes taste seriously and the available flavours are: chocolate smooth, vanilla, strawberry, banana, choc mint, cookies & cream plus this is the only one of the listed brands with an unflavoured option.

Verdict – This product is pretty much everything you would expect from MyProtein.  It offers decent performance at a reasonable price.

Optimum Nutrition Pro Complex Gainer

Optimum Nutrition Serious Mass

There’s a reason why Optimum Nutrition is one of the most respected names in the health and fitness world and Pro Complex Gainer lives up to its usual gold standard.

The exact nutritional values depend on the particular flavour, however as guideline, each 165g serving contains 60g of protein, along with 85g of carbohydrate and 650 calories.

The protein is mainly from whey (concentrate and isolate) but there’s also casein and egg albumen.

According to the various labels, the available flavours are: banana cream pie, double rich chocolate, strawberry cream and vanilla custard, which taste remarkably similar to regular banana, chocolate, strawberry and vanilla.  Having said that, the flavours are very acceptable.

Verdict – It’s Optimum Nutrition, therefore this is going to be a top-quality product, the only question is whether or not it matches your goals.

Optimum Nutrition Serious Mass

Optimum Nutrition Serious Mass

Another contender from Optimum Nutrition.  Again the exact nutritional values of Serious Mass depend on the flavour you choose and whether you mix it with water or milk, but a reasonable expectation is 50g of protein along with 254g of carbohydrate and 1250 calories.

The main source of protein is whey (concentrate and isolate) with the addition of casein and egg albumen.

There’s also 25 vitamins and essential minerals plus Creatine, Glutamine and Glutamic Acid.  Available flavours are: banana, strawberry, vanilla, chocolate and chocolate peanut butter.

Verdict – Another rock-solid product for Optimum Nutrition.  Being lighter on protein but higher in carbohydrate than its sibling Pro Complex Gainer means that it’s a good choice as a post-workout drink or for between meals.

The Protein Works Total Mass Matrix Extreme

The Protein Works Total Mass Matrix Extreme

The Protein Works is a relative newcomer to the health and fitness scene, but it’s been making a name for itself with products which are both high-quality and innovative.

In that vein, each 115g serving of Total Mass Matrix Extreme offers 55.9g of protein accompanied by 158.5g of carbohydrate and 951 calories.

TPW describes this product as having a Tri-Blend Protein Source, in other words, it contains whey protein concentrate, micellar casein and milk protein.  Likewise the Multi-source Carbohydrate Blend translates as a mixture of maltodextrin, oat flour, whey permeate, dextrose and TPW™ supergrains.

There’s also a multi-source creatine blend, L Glutamine, a Vitamin B Vitablend and  healthy fat Medium Chain Triglycerides.  Available flavours are: banana smooth, chocolate silk and strawberries ‘n’ cream.

Verdict – While TPW does seem to like using fancy marketing terms to describe fairly simple concepts, they do know their science and nutrition and their products are effective as can be seen by the many rave reviews they get.  They’re also fairly affordable and hence excellent value for what you get.

Bulk Powders Informed Mass

Bulk Powders Informed Mass

The Bulk Powders website states their aim for this product in very clear terms “Ignore the costs and just create the very best mass gainer possible.”.

Well there’s some stiff competition out there for the title of “very best” but Informed Mass is certainly a contender.  Each 150g serving contains an impressive 45g of protein & 566 calories.

The protein comes entirely from whey with 65% being ultra and micro-filtered Pure Whey Isolate® 90 and the remaining 35% being undenatured Pure Whey Protein™.

The (almost) 75g of carbohydrates come via ultra fine Scottish oats, which were chosen partly for their low Glycemic Index value and partly for their texture (which also helps with effective mixing).

Each serving also contains: 5g pharmaceutical grade Leucine, 5g Creatine Monohydrate, 3g Glutamine Peptides and 1.5g HMB.  The flavours currently available are double chocolate and strawberries & cream.

Verdict – Limited flavours and a somewhat higher price than your average Bulk Powders product but excellent performance and great value for money.

Sci MX Muscle Meal Hardcore

The term “muscle meal” is a pretty good description for this product.  Every 155g serving provides 48g of protein, 91.9g of carbohydrates and 597 calories.

The protein content is described as being GRS 9-Hour® protein, which in practical terms means: whey protein concentrate, calcium caseinate, hydrolysed wheat protein, soy protein isolate and whey protein isolate.

The carbohydrate content is provided by maltodextrin, dextrose, fructose, rice starch.  There’s also an impressive array of vitamins and minerals.  Available flavours are chocolate, strawberry and vanilla.

Verdict – This is a good, all-round product at a reasonable price and hence offers compelling value.

Overall – Best Weight Gainer UK Protein

There are only three hard and fast facts to remember out of this review.

Vegetarians should skip Muscle Pharm – Arnold Schwarzenegger Iron Mass

Anyone with a significant dairy intolerance should head straight to Muscle Pharm – Arnold Schwarzenegger Iron Mass

Anyone looking for an unflavoured option should head straight to MyProtein Hard Gainer Extreme

On top of this, it’s worth noting that as one of the lighter products on this list, CNP Professional Pro Mass is probably best suited to easing into a bulking programme or coming to the end of one or it can be used by those who just want to bulk up a little or to maintain muscle once it has been gained.

For the rest, your choice will depend on your specific needs and your preferences in terms of taste and, of course, your budget.  Whichever one you choose, you can rest assured that if it’s on this list, it’s because the product is one of the best around.

We will be happy to hear your thoughts
