  • DESCRIPTION

    Progain Mass Gainer Protein Powder

    Progain mass gainer protein powder

    Maxi Nutrition Progain is a high-performance mass gainer designed to help you build size, increase strength and consistently hit your daily calorie targets.

    Each serving combines high-quality protein and complex carbohydrates in a clean, scientifically balanced formula to support muscle growth, recovery, and performance. Our evolved formula also offers improved mixability and easier digestion for consistent daily use.

    With 525 calories and an optimal 2:1 carbohydrate-to-protein ratio, Progain helps convert training into real muscle gains in a convenient shake.

    It is ideal for:

    • Supporting a calorie surplus for muscle gain
    • Post-workout recovery nutrition
    • Daily weight and size gain goals

    Built for hard gainers and serious trainees alike.

  • WHY CHOOSE

    Why use Progain?

    To build muscle, you need more than protein alone you need a consistent calorie surplus supported by carbohydrates, protein, and recovery nutrition.

    Progain helps you achieve this in a simple, convenient way:

    • 500+ calories per serving without large meals, helping avoid “appetite fatigue”
    • 30g high-quality protein for muscle repair and growth
    • Carbohydrates to fuel training and replenish glycogen stores
    • A clean formula with a full amino acid profile for effective digestion & absorption

    Ideal for anyone who struggles to consume enough calories through whole foods alone.

    Why timing and consistency matter

    Building muscle requires more than hard training alone. Protein supports muscle repair, but calories provide the energy needed to maximise growth. Without enough intake, progress can be limited.

    Progain helps bridge the gap by delivering convenient calories and protein post-workout or between meals, helping you maintain a steady energy and protein supply throughout the day.

    Why Progain is different

    Unlike many mass gainers, Progain is formulated with a clean ingredient profile:

    • No artificial colours
    • No artificial flavours
    • No added thickeners
    • Low sugar formula
    • Gluten-free, soy-free, vegetarian-friendly

    A clean shake designed for smooth mixing and easy digestion.

    Informed-Sport Certified

    Informed-Sport is a globally recognised supplement certification programme. Every batch is independently tested for banned substances and manufactured to high-quality standards for athlete confidence.
