Progain Mass Gainer Protein Powder

Maxinutrition Progain is a scientifically formulated mass gainer protein designed to help you achieve your muscle-building and performance goals. Developed using advanced sports nutrition research, Progain delivers the optimal balance of high-quality protein, complex carbohydrates, and essential nutrients to fuel muscle growth, recovery, and overall training performance.

Why Choose Progain Mass Gainer?

If you’re a hard gainer — someone who struggles to put on size despite training hard — or you’re looking to add lean mass as part of your strength or performance programme, Progain is the perfect solution. Each serving delivers:

Over 500 calories to support a calorie surplus for muscle growth.
37-38g of protein from whey protein concentrate to promote muscle repair and maintenance.
Targeted carbohydrate blend to replenish glycogen stores and provide sustained energy.
Added vitamins and minerals to support metabolism, immunity, and overall wellbeing.

Progain is designed for athletes, gym-goers, and anyone with increased calorie and nutrient needs due to intense training or a fast metabolism.

Clean, Quality Ingredients

Unlike many mass gainers on the market, Progain contains no artificial colours, artificial flavours, or unnecessary thickeners. This means you get a cleaner taste, better consistency, and a formula that’s easier to digest. It is also:

Gluten-free – suitable for those with gluten sensitivities or coeliac disease.
Soy-free – avoids common allergens.
Vegetarian-friendly – suitable for a wide range of dietary needs.

Delicious Flavours to Keep You Motivated

Sticking to a nutrition plan is easier when your supplements taste great. Progain is available in four indulgent flavours:

Chocolate – rich and satisfying for any chocolate lover.
Vanilla – smooth and versatile, perfect for mixing with fruit or oats.
Strawberry – light, fruity, and refreshing.
Banoffee – a unique blend of banana and toffee for a dessert-like treat.

Scientifically Backed Performance

Protein plays a vital role in muscle protein synthesis — the process by which your body repairs and builds muscle tissue after training. Progain’s 38g protein per serving provides enough high-quality amino acids to maximise recovery and growth. The complex carbohydrate blend ensures your muscles are replenished with glycogen, reducing fatigue and helping you perform consistently in your next session.

The Informed-Sport certification guarantees that every batch of Progain is tested for banned substances, making it safe for professional and competitive athletes.

For optimal results, consume Progain:

Post-workout – to kickstart recovery and replenish energy stores.
