Shop Weight Gainers at Myprotein


Building mass takes more than just turning up at the gym. You need a calorie surplus, and getting enough food in each day can feel like a full-time job. Weight gainers turn that challenge into something manageable, packing serious calories and protein into one shake.


These high-calorie formulas combine protein with carbohydrates to give your body the fuel it needs for training and the building blocks for muscle. Protein contributes to a growth in muscle mass1, making these blends a practical choice when whole food alone isn't cutting it.



Who Weight Gainers Are For


If you've got a fast metabolism or struggle to eat enough throughout the day, weight gainers bridge that gap. They're designed for anyone looking to increase their calorie intake without having to force down another meal.


Hardgainers find these particularly useful, as do athletes in heavy training phases who burn through calories faster than they can realistically eat. Whether you're new to the gym or deep into a bulking phase, these formulas make hitting your daily targets far more achievable.



When to Use Weight Gainers


Many people reach for a weight gainer between meals or as a post-workout shake when solid food isn't practical. First thing in the morning works too, especially if breakfast tends to be rushed or skipped entirely.


The key is consistency rather than perfect timing. Some prefer splitting servings across the day to avoid feeling overly full, whilst others find one large shake fits better into their routine. Mix with water for a lighter option or with milk to push the calorie count even higher.



Weight Gainers Benefits


High Calorie Content

Weight gainers deliver substantial calories in liquid form, making it easier to maintain a surplus without constantly eating. A single serving can provide anywhere from 400 to over 1000 calories, depending on the formula and how you mix it.


Protein for Muscle Mass

Each shake contains a meaningful dose of protein, which contributes to the maintenance of muscle mass2. This ensures your body has what it needs whilst you're pushing through training and recovery.


Carbohydrate Fuel

The carbohydrate content in these blends provides the bulk of the calories, giving your body readily available fuel. This macronutrient balance supports the demands of regular training without relying solely on protein.


Convenient Nutrition

Drinking calories is significantly faster than preparing and eating multiple meals. Weight gainers fit into busy schedules, travel plans, and moments when your appetite just isn't cooperating with your goals.

FAQs



What are weight gainers?

Weight gainers are high-calorie supplements that combine protein and carbohydrates to help you increase your daily calorie intake. They're designed for people who struggle to eat enough food to support their training and mass-building goals.


How do weight gainers differ from protein powders?

Protein powders focus primarily on delivering protein with minimal carbohydrates and calories. Weight gainers flip that balance, providing substantial carbohydrates alongside protein to create a calorie-dense formula that supports a surplus.


A typical protein shake might give you 20-30g protein and 100-150 calories, whilst a weight gainer can deliver 30-50g protein with 400-1000+ calories depending on serving size and mixing liquid.


How much should I take?

Start with one serving daily and assess how it fits with your overall food intake. Some people use a full serving between meals, whilst others split servings throughout the day or adjust the powder-to-liquid ratio to control calorie density.


Track your weight over a few weeks to see if you're gaining at the right pace, then adjust up or down as needed. The goal is consistent progress, not rapid weight gain that's mostly fat.


Can I use weight gainers as meal replacements?

Weight gainers work better as additions to your diet rather than replacements for whole meals. Real food provides fibre, micronutrients, and variety that supplements can't fully replicate, so think of these as tools to boost your total intake alongside regular eating.


That said, they're useful when meals genuinely aren't an option due to time constraints or appetite issues. Just don't let them become your primary source of nutrition.


What's the best way to mix weight gainers?

Most people use a shaker or blender with water or milk. Water keeps the calorie count at the stated serving size, whilst milk adds extra protein, carbs, and calories if you need an even bigger boost.


Blending with oats, nut butter, or banana creates an ultra-high-calorie shake that's useful during serious bulking phases. Some formulas mix better than others, so adjust your liquid ratio if the texture isn't to your liking.


Will weight gainers make me put on fat?

Any calorie surplus can lead to both muscle and fat gain, whether it comes from weight gainers or whole food. The key is controlling the rate of weight gain through your total calorie intake and maintaining consistent training.


Gaining 0.25-0.5kg per week is generally sustainable for most people trying to build mass. Faster than that and you're likely adding unnecessary fat. Track your progress and adjust portions accordingly.


Who developed these products?

Myprotein's expert nutritionists developed these formulas to meet the needs of people struggling to gain mass through diet alone. Each product is designed with specific macro ratios and quality ingredients to support different calorie requirements and training goals.


How do I choose between different weight gainers?

Look at the calorie and protein content per serving, then consider how that fits your daily targets. Higher-calorie options suit hardgainers or very active individuals, whilst moderate formulas work better if you're already eating substantial meals.


Check the ingredient list for carbohydrate sources and any added extras like creatine or vitamins. Some prefer simple formulas they can customise themselves, whilst others want everything included from the start.


Can I take weight gainers alongside other supplements?

Weight gainers combine well with most supplements since they're essentially food in powder form. Many people stack them with creatine, pre-workout, or multivitamins as part of their broader nutrition strategy.


Just watch your total protein intake across all sources to ensure you're not massively exceeding your requirements whilst neglecting carbohydrates and fats. Balance matters more than simply maximising every supplement.
