    SLEEP PREP

    Sleep Prep

    A short, rich hot chocolate drink that supports sleep onset.

    Designed for nightly use, Sleep Prep helps you build better sleep into your routine – mix one 10 g scoop with 100 ml of hot water and drink around 1 hour before bed.

    When you’ve trained hard, worked late, or carried the weight of the day, your system doesn’t always switch off on cue. Stress hormones stay high, thoughts keep running, and that restless edge makes healthy sleep harder to maintain.

    WHEY PROTEINS

    100% Whey

    100% Whey is made with instantised, ultra-filtered whey protein concentrate – a form of protein that keeps more of the natural nutrients from whole whey. With around 70% protein, it naturally contains healthy fats, carbohydrates, and bioactive peptides.

    That fuller nutritional profile gives it a creamier texture and a richer, more satisfying taste.
    Protein isn’t just for training – it’s the raw material your body uses to build and repair itself. Muscles, skin, hair, nails, enzymes, even your immune system all rely on it.

    Training pushes your body's demand for protein even higher. Every session creates tiny tears in muscle fibres – the signal to grow stronger – but without protein, they can’t rebuild. Recovery slows, fatigue lingers, and progress stalls.

    Whey protein concentrate gives your body a fast, high-quality supply of those building blocks. It delivers all the essential amino acids – including leucine, the trigger for muscle growth – and keeps more of the natural nutrients in whole whey, such as healthy fats and bioactive peptides. With added enzymes and friendly bacteria, it digests smoothly so more of that protein is absorbed and put to work.

    In the short term, that means fuel your body can use and quicker recovery after training. Over time, it helps you maintain lean muscle, supports your metabolism, and strengthens the systems you rely on – keeping you strong and capable in both training and life.<

    Each serving of 100% Whey delivers 21g of protein in a rich, creamy shake.

    Made with whey concentrate, it retains more of the natural nutrients in whole whey – including healthy fats and bioactive peptides – for a fuller profile. It’s the fuel your body needs to recover, rebuild, and stay strong day after day.
