Jack Holt

Are you focused on that bulk? Ready to unlock your full potential and gain skin-splitting muscle? It's time to turn those goals into a reality with the best supplements for muscle gain and bulk. 

Whether you are undergoing a progressive overload, need more support for those rippling gains or need a post-workout recovery boost, we have you covered! At Anabolix Nutrition, we are built for lifters by lifters, so we know exactly what you need - because we have been in your position. 

So, up your stack and reach your goals with the best products for muscle gain. We’ve highlighted the FOUR main categories we swear by for muscle gain and bulk! 


When it comes to muscle growth, Creatine is him - the GOAT! With so much research showing its benefits for increasing muscle strength and size, its effectiveness is unparalleled. 

This organic compound supports your muscle's production of adenosine triphosphate (ATP). Why is this important? This supercharged, energy-carrying molecule gives your muscles extra energy to lift more. Creatine also increases water retention in your muscle cells, producing signals and hormones for muscle growth. 

More importantly, for all you lifting enthusiasts, creatine helps increase muscle strength and output when undertaking short, high-intensity resistance training. That means those big lifts and reps become even bigger! Start with a loading phase of 0.3 grams of creatine per kilogram of body weight for five to seven days and watch that bulk go up!

  • Ready to start taking creatine and increase strength, power and performance? Don’t wait around for your delivery—supercharge it with monohydrate creatine! Our Cr3atine is one of the most trusted bulk supplements on the market for delivering results. It is 100% pure, unflavoured and easily stackable. If you haven’t started on creatine yet, this is your chance - don’t settle for less!

Whey Protein: 

There’s a reason why whey protein is one of the most popular supplements on the market. This legendary supplement stimulates muscle protein synthesis and reduces muscle breakdown, supporting impressive muscle mass. Whey contains all nine essential amino acids for muscle growth and recovery (more on that later!). This gives it a high amount of the muscle-building amino acid leucine, one of the most important for muscle growth.

When it comes to protein powder for muscle gain, the more whey, the better. Some suggest that to increase muscle mass, people who lift regularly need 1.2-1.7 grams of protein per kilogram of body weight per day, while others suggest 1.7-2.6 grams. Luckily, our whey protein has been scientifically researched and formulated with the perfect amount in each serving. 

  • Isolate is a fast-acting hydrolysed WPI (whey protein isolate) that will support your muscles immediately, without the digestive discomfort associated with other products. With 26.6g of pure protein in each scoop, this low-carb and low-fat option is ready to support your muscle growth goals. Isolate blows other WPI’s out of the water with higher glutamine and BCAAs content, for lean and clean results that absorb quick and support you even quicker. Did we mention it’s the perfect accompanying protein for those bulking/weight gain phases when you are only looking for pure lean muscle mass? That’s right, no need to worry about extra calories. There is only one option when it comes to WPIs and it's right here. 
  • Primal is all about facilitating your physical evolution! This whey protein is the high-quality 31.2g of protein you NEED if you are searching for the best protein powder to gain muscle mass. With its multi-phasic release from added casein, you are getting a diverse selection of proteins and a high amount of muscle-building and health-supporting amino acids. Primal offers a 2830mg dose of Leucine to maximise that sweet muscle growth and recovery, along with 6320mg BCAA’s and 2280mg Glutamine. 

Weight Gainers:

If you have been looking at how to bulk up fast, we have the answer. Weight gainers are the kings of the bulk. When you are looking to gain weight, you need a calorie surplus. But getting these calories in your diet alone can be impossible for some people, particularly if you need help to gain weight. 

With added protein, weight gainers give you the calories you need for a bulk that is all about those big, rippling muscles. These calories come from carbohydrates and have a dense nutrient profile.

  • Our Monst3r gainer is no watered-down supplement! Support your weight gain and management program and help maintain and build muscle with 87.5g of carbs. This weight gainer is a goliath combination of Whey Protein Concentrate, Whey Protein Isolate and Milk Protein Concentrate. In a single serving, you get 35.3 grams of sustained-release protein and a massive 561 calories for peak bulk. We also include Digezyme and other state-of-the-art ingredients for a formula you can trust to support those heavy reps. Plus with the additional essential and non-essential amino acids, you get an added boost for recovery. There is no area this mass gainer doesn’t cover, if you need a mass gainer then this should be straight in your cart! 
  • Mammoth offers a different approach for those looking for pure protein and carbs! This formulation is all about driving your protein synthesis and achieving that sweet, lean muscle growth. With a 1:1 scientifically researched ratio of protein and carbohydrates, there are under 250kcal per serving and no unwanted fats. Instead, you get a blend of Whey and Casein in five different varieties, offering a diverse amino acid profile and absorption that mimics food consumption. This includes 5000mg of Leucine and 2800mg of Glutamine, making it an anabolic protein that stimulates maximum muscle protein synthesis. That means you get gains and lots of them. This weight gainer also delivers a visit from our old friend creatine with 3000mg of muscle-growing support! Mammoth is a complete formula, offering a no BS approach to peak gain! Did we mention it digests easily too? 

Branched-Chain Amino Acids:

The best supplements for muscle gain provide the nutrients your body needs. Amino acids are crucial to muscle growth and recovery. There are 22 amino acids in total, and nine of these are essential (EAAs) because our body cannot produce them. 

Leucine, isoleucine and valine are the daddies of amino acids for muscle growth. These Branched-Chain Amino Acids comprise ⅓ of muscle protein and are vital to muscle synthesis. It's not just growth that these amino acids stimulate, but recovery too. If you are constantly pushing your body, you need BCAAs to support muscle repair and reach your spartan muscle build. 

  • Fuel3d doesn’t just have these legendary BCAAs for muscle growth but all nine of the essential amino acids! Plus, with ingredients for impressive bulk, like Senactiv®, and delicious flavours, it's one of the most underrated yet important muscle gain supplements. There are also benefits for cognitive function you get from Fuel3d. From enhancing recovery to supporting focus and energy, it's an important part of your bulk stack that you can't miss.
