When it comes to finding a reliable mass-gaining supplement, the search can be quite daunting, with so many products available on the market (there are almost 80 in the UK alone!). 

CNP Professional Pro Mass is designed for individuals looking to pack on lean muscle mass and increase their strength. This British supplement boasts a blend of high-quality complex carbs and proteins that help gym-goers in achieving their weight gain goals efficiently. 

However, it might not be the ideal choice for everyone, as some hardgainers may benefit from a higher-calorie formula.

In this CNP Professional Pro Mass review, I'll delve deeper into the ingredients, flavours, and user feedback on this popular gainer.

CNP Pro Mass Ingredients

In this section of my CNP Pro Mass review, I'll discuss the main components of this weight gainer, specifically the top three building blocks that make up its formula: 35g of Protein, 48g of Carbs, and 5g of Fat.

35g of Protein

When it comes to muscle growth and recovery, the protein content in CNP Pro Mass 4.5kg plays a vital role. Each serving provides a generous 35g of high-quality protein, which contributes to muscle maintenance, repair, and growth. 

As I noted earlier in my CNP Pro Mass review, this mass gainer utilises a blend of premium proteins from sources such as whey and casein, ensuring a sustained release of amino acids during the post-training period.

48g of Carbs

CNP Professional Pro Mass includes 48g of complex carbs in each serving, helping you to power through training sessions and recover more efficiently. Additionally, these carbs support weight gain by supplying the extra calories that are necessary for hardgainers and those with fast metabolisms to put on size.

5g of Fat

Lastly, CNP Pro Mass contains 5g of fat per serving, providing additional calories to support weight increase and muscle gain. Good fats are essential for overall health and well-being, and they can also help maintain hormone balance and promote energy production. 

In this case, CNP Pro Mass keeps the fat content relatively low, ensuring that the product is calorie-dense but not overly high in unnecessary fats.

CNP Professional Pro Mass Features

90 Servings Per Tub

I appreciate the value for money provided by CNP Professional Pro-Mass, as it offers 90 servings per 4.5 kg tub—way more than average for a mass gainer. The big tub is perfect for those taking mass gainer supplements consistently and allows you to worry less about continually restocking.

Mixes Easily With Water Or Milk

One of the often-overlooked features of a mass gainer is its mixability. But how a shake mixes is actually really important. After all, if half the powder sticks to your shaker cup, then you’re never going to realise the supplement’s full benefits.

Thankfully, CNP Professional Pro-Mass mixes easily with water or milk, making it convenient to whip up on the go or at home. It’s great that you can enjoy a smooth and well-blended shake without any annoying lumps or residue.

Can Be Taken Any Time Of The Day

CNP Professional Pro-Mass is suitable for taking at any time of the day. This is great for busy individuals who don't have a set schedule. You can consume it pre-workout, post-workout, or in between meals, allowing you to incorporate it into your daily routine effectively.

If you’re looking for a shake that’s a bit leaner and specifically designed for the post-workout anabolic window, then I recommend reading my CNP Pro Recover review as well. 

Only Uses Quality Protein Sources

CNP Professional Pro-Mass is formulated with high-quality protein sources to support muscle growth and repair. This ensures that you’re getting the most out of your mass gainer supplement without having to worry about compromising on quality.

Some other mass gainers may have more protein, but they tend to bulk up their numbers with lower-quality protein sources and/or cheap filler amino acids.

How To Use CNP Pro Mass

Two CNP mass gainers

I recommend starting with the proper dosage of CNP Professional Pro-Mass to get the most out of this supplement. Obviously, though, if your calorie requirements are lower, you can use 2 scoops instead of 4.

To prepare a serving, mix 4 scoops (approximately 100g) of the powder with 568ml (1 pint) of cold water or skimmed milk. 

You can adjust the amount of liquid to suit your preferred consistency, but be mindful of the overall calorie content if you opt for milk instead of water. For best results, use a shaker bottle or an electric blender so that your shake is nice and smooth (i.e. don’t just stir it with a spoon).

To maximise your CNP Pro Mass results, I suggest consuming it at least twice a day. One serving can be taken first thing in the morning, which helps in kick-starting your day with the necessary nutrients for muscle growth. 

Another serving can be enjoyed after your workout to aid in muscle recovery and glycogen replenishment.

In addition to (or instead of) mornings and post-workout, you can also consume a serving of CNP Pro Mass in between meals as a snack. This would not only help in meeting your daily calorie requirements but also assist in maintaining a steady supply of nutrients for muscle growth throughout the day.

Who Should Avoid Taking CNP Pro Mass?

As I gathered information from various CNP Pro Mass reviews and forums, it seems that CNP Pro Mass might not be suitable for everyone. 

Firstly, if you need a really high-calorie gainer, CNP Pro Mass might not be the best option for you. Since it allows for a few different options to make it last longer, it doesn't directly cater to those searching for a more intense weight gain supplement. Read our CNP Mass XL review if you’re looking for a more hardcore mass gainer.

Secondly, if you merely want to maintain your current weight, then you probably don’t need to buy CNP Pro Mass (or any weight gainer, for that matter). This supplement is specifically designed to promote mass gaining and is better suited to individuals with weight gain targets, rather than those seeking to preserve their existing body mass.

Furthermore, if you consume two of these shakes per day in addition to your regular meals, then it’s possible that you might get a bit bloated. If you have a history of digestive discomfort or sensitivities, you might want to reconsider using CNP Pro Mass and find another protein supplement that suits you better.


I've looked at various sources for my CNP Professional Pro Mass review and found that this gainer has a mix of opinions, with most of them being positive. 

Considering the variety of CNP Pro Mass reviews, I'd suggest trying out CNP Professional Pro Mass for yourself and monitoring your personal progress. It might work wonders for you, or you may find it's not the ideal choice for your needs. Don't be afraid to experiment and find the supplement that works best for your unique situation.

Overall, if you want to buy CNP Pro Mass, I say go for it. While I do think there are some better options on the UK market at this time, you can never go wrong with a CNP supplement, that’s for sure.
