PRODUCT INFO

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.

UNDER THE SURFACE

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.

HOW TO USE

Consume 1–3 servings daily, ideally before or after training.

Mix 30g (around one heaped scoop) with 200ml water or skimmed milk in a shaker or blender. For a thicker consistency, use less liquid or non-skimmed milk.

Once mixed, drink immediately. The scoop measures volume, not weight, so for accuracy we recommend using scales.

This product is a food supplement and should be used in conjunction with a varied and balanced diet and a healthy lifestyle, not as a substitute for such. Do not exceed the stated daily dose. Not intended for use by anyone under 16. Keep out of reach of young children.
