Best protein powder for bulking

Best protein powder for bulking

If you want to bulk up, a good protein powder is essential.

If you’re training your muscles frequently, they need plenty of protein to repair and grow bigger.

Of course, you can (and should) get plenty of protein from whole foods – but protein shakes allow you to get quick and convenient hits of protein to help you reach your protein intake goals.

However, the choice of protein powders available can be mind-boggling, and you might not know what ingredients are best for your situation.

I’ve used tons of protein shakes over the years, so here’s my list of the 9 best protein powders for bulking… and a simple breakdown of their pros and cons.

Bulk powders pure whey protein

Bulk Powders are known for their high-quality protein powders and this one is no different. The whey protein is derived from grass fed cows, meaning the milk is of a higher quality. It’s a product that mixes well, tastes great and packs a nutritional punch.

The high quality milk gives the protein powder a nice blend of amino acids, is gluten and GM free and naturally low in fat and sugar, whilst still packing in plenty of protein. The protein powder comes in at a surprisingly affordable price too. It mixes very well and is available in a huge range of flavours – 19 overall! The quality of the milk can be a big feature for people who are particularly interested in clean eating.

It is available in eight different flavours and at around £25 for 5kg is a very affordable supplement. As a weight gainer it is smaller in serving size than some of the others, but it still offers a lot of calories and protein by volume.

PBN Whey Protein Powder

The product mixes well, taste reports say it tastes good and it delivers nutritionally. The PBN product is available in eight different flavours and is delivered in a 2.27kg tub, which contains 75 servings.

Optimum Nutrition Gold Standard Whey Protein Powder

Many people consider the Optimum Nutrition Gold Standard Whey to be the best protein of its type on the market, with it’s whey isolate, concentrate and hydrolysed blend. This is a premium product so comes in at a premium price, but scores well with users on its mixing, flavour and general quality, all of which are really important – poor mixing makes for a pretty awful drinking experience.

The protein blend means it can be used at any time of the day and is beneficial, so you have convenience with the product – it’s not ‘best used’ at a particular point in your day. It comes in 15 different flavours, offering plenty of variety as well. Overall it’s an almost pure protein hit, with very low fat and carbohydrates per serving so is nutritionally sound when it comes to adding mass without adding additional fat.

What to look for in a bulk protein powder if you want to build muscle

Not bulk protein powders are the same – there are different recipes, ingredients, protein types, addition of amino acids, addition of multivitamins and minerals etc. If you want to spend your money wisely, you’d be best understand what a few of these basic terms mean, allowing you to pick the best product for you and your needs.



This is key – muscle gain requires a calorie surplus, so you need to be consuming more calories than you are burning. If you want to gain weight, you need to look at the amount of calories you’re consuming and make sure you are achieving this surplus every day.

The calorie content of a weight gainer is important, so don’t buy a low calorie protein powder if you really need to add extra calories. It just won’t work for you. Always check the nutritional information in this guide for advice.



Protein is the macronutrient required to build muscle – generally speaking, the more protein a supplement contains, the better. That being said, you need to look at the type of protein.

Blended proteins are better for mass gainers as they allow protein to be released over a longer period of time than supplements only containing whey protein. Whey is a fantastic protein, but it is generally quick-release so is only really useful immediately post workout.

A blended protein in a mass builder would typically mix whey, milk and egg proteins which will allow the benefits to be spread over a longer period of time. You may also see the premium products will add additional amino acids into their mix, making the product potentially more anabolic.



How to use a bulking protein powder

The guidelines for each product vary, but typically speaking you’ll take a bulking protein powder daily, with a double dose on training days to offset the calories you burn whilst in the gym (especially if you are training Muay Thai).

Depending on your goals to build muscle and add mass, you’ll mix the products with water or milk, with milk obviously adding more calories to the shake. If you want to go extreme, you could mix them with whole milk and add additional calories.

Mixability of powders vary enormously, but there are a few basic guidelines….

  1. Put the powder in first, liquid in second. THIS IS VITAL – if you do it the other way round, you WILL end up with lumps.
  2. Ideally, use an electric blender – no amount of shaking will beat a blender.
  3. If you aren’t using an electric blender, don’t fill your shaker to the top with liquid – you need room for the liquid to move to mix the powder.
  4. Make sure your shaker has an ‘agitator’ – either a coil in the bottle or some sort of mesh to mix the powder. It helps to mix the product better.

Follow these and you won’t go far wrong.



Choosing your protein powder for bulking

Look at your requirements in detail – do you need the calories or the protein more? Some people want the protein more than the calories because they don’t get much protein from their diet (vegetarians for example). Them, look at your allergies – is there anything you should avoid? That can inform your choice.

Read reviews – do they taste good? Do they mix well? Is there a flavour in the range you like the sound of? These are all points to consider.

Finally, look at budget because that can be key – there’s a wide range of prices. Look at what you can afford and make your choices based on all of the above points. You won’t go wrong if you follow the advice in this guide.
