Live prices
Looking for affordable whey blends at Chemist Warehouse? This comparison page shows current prices as of May 2026 and is refreshed regularly to help you find budget-friendly options. Prices start from $25.99 for Vital Strength High Protein, though cheaper doesn't always mean better value. Body Science High Protein at $32.44 actually costs just 2.6 cents per gram of protein, while the lower-priced Vital Strength works out to 4.9 cents per gram. When comparing products of different sizes, always divide the total price by the grams of protein per container, not just the overall weight. This gives you the true cost per serve of actual protein. The products below are sorted by upfront price, but keep an eye on the cents per gram column if you want maximum bang for your buck.
Check the price per 100g of actual protein, not just per kilo of powder. A cheaper tub with less protein per serve often costs you more.
How the live ProteinPrice Value Score is calculated
Vital Strength High Protein ranks 1 on this list at $25.99 for 750g. It scores 6.4 out of 10 for value, which is decent but not exceptional. The smaller 750g tub means you'll be restocking more often than with bigger options. At 4.95 cents per gram of protein, it's the most affordable whey blend at Chemist Warehouse right now. Good entry point if you're testing the brand.
Body Science High Protein ranks 2nd on this list with a perfect 10/10 value score. At $4.51 per 100g, it's genuinely competitive among whey blends at Chemist Warehouse. The 720g tub is smaller than typical kilogram options, so you'll restock more often. Caramel honeycomb is a solid flavour choice if you're after something sweeter than standard chocolate or vanilla.
Musashi High Protein Powder ranks 3rd on this list but offers poor value at $5.27 per 100g. The value score of 1.4 out of 10 reflects its premium pricing without corresponding benefits. It's not on sale, which doesn't help its position. The 900g tub is a standard size, and vanilla is widely available. Unless you're specifically loyal to the Musashi brand, better value options sit above it on this comparison.
Optimum Nutrition's Performance Whey ranks 5th on this list at $67.49 for 2kg. The value score of 4.6 out of 10 suggests it's middle-of-the-road for budget hunters. It's a solid choice if you prefer vanilla flavour and trust the ON brand name, but you'll find better bang for buck higher up the rankings. Not currently on sale at Chemist Warehouse.
