How we calculate
Not just the cheapest tub — the best value protein
Pack price alone is misleading. A 1kg tub at £20 can cost more per gram of protein than a 5kg at £55. We divide the pack price by total weight and protein density to find the true cost per gram of protein — the only metric that lets you compare products of different sizes and brands fairly. The live example on the left shows exactly how that calculation plays out on today's prices.

Whey Protein
What Whey Protein Actually Means
Whey is the most widely used protein supplement in the UK for good reason. It absorbs quickly, sits well on most stomachs, and delivers a complete amino acid profile. Concentrate, isolate and clear whey all suit different goals and budgets, so understanding the differences helps you pick the right product.

Mass Gainer
Calories Per Pound, Not Just Pack Price
Mass gainers are designed for people who struggle to eat enough calories to put on weight. They combine a protein base with a high carbohydrate load to push the calorie count up significantly per serving. Whether they suit you depends on your calorie needs, digestion and how hard it is for you to eat in a surplus from food alone.

Vegan Protein
Pea, Soy And Plant Blends Compared
Plant-based protein has come a long way. Pea, soy, rice and blended formulas each have different amino acid profiles, textures and uses. Modern pea-and-rice blends are now close to whey in terms of muscle-building potential, making vegan protein a genuinely strong option whether you eat meat or not.
Creatine
Monohydrate vs Capsules And Blends
Creatine is one of the most researched and consistently effective supplements available. Monohydrate powder is the standard form, backed by decades of evidence for strength and power output. Capsules, gummies and flavoured blends exist but offer no performance advantage over plain monohydrate at a fraction of the cost.
