How to Choose Your Perfect Mass Gainer

Feel like you're slaving away at the gym and not seeing the results you want? When you're putting in the hard yards and you're not getting the gains you're expecting, it can be more than frustating - it can make you want to give up altogether! If you're feeling like you need the extra support adding lean muscle size, you're in the right place.

Of course you know that eating enough calories and getting enough protein (1.6-2.4 grams of protein per kg of body weight) is key to building muscle mass. However, acheiving muscle gain is a hard task - especially once you move past the first few weeks to months of your training (known as 'newbie gains').

This when you need to get more serious about your training and eating. In this article, you'll find the top-rated weight gainer protein powders that are ranked in terms of calories, so you can pick one that fits your lifestyle best.

Signs you need a mass gainer protein:

  • You're struggling to gain weight
  • You are highly active during the day (looking at you, tradies!)
  • You want to achieve your muscle mass results quicker
  • You want to reduce your food volume (too many heavy meals!)
  • You're super busy and simply can't find the time to sit and eat as much as you need to
  • You need extra recovery support

What will you find in a mass gainer?

  • Lots of calories, naturally!
  • Protein, carbs and fat ratio to fit your macros and help fuel growth
  • Amino acids for optimal muscle growth
  • Digestive enzymes to help nutrient absorption
  • Flavour
  • Added nutrients

These formulas below tick the boxes in terms of nutrition, calories, amino acids and taste! Let's dive in.

Find the top-rated below, ranked from least to most amount of calories per serve.

1. I Want Lean Gains:

If you want to add some size without fearing putting on extra body fat, then one of these lean gainers are perfect for you. Remember, your daily calorie intake is key.

Using one of these gainers can help you add a little more dietary intake to your day, when you want to take a slower and more conservative approach. Of course, you can always take more than one serving if you want to up the ante!
