Live prices
Looking for affordable protein powder at Chemist Warehouse? This comparison shows options sorted by price, current as of May 2026 and refreshed regularly. The cheapest option right now is Body Science High Protein at $32.44, though price alone doesn't tell the whole story. When comparing different sized tubs, check the cost per gram of protein rather than just the sticker price. For example, Body Science High Protein works out to 2.6 cents per gram of protein, while some pricier options cost over 11 cents per gram. We've included both whey and plant-based options from brands like Body Science, Musashi, and others commonly stocked at Chemist Warehouse. The table below shows current prices, value scores, and protein costs so you can find what fits your budget and nutritional needs.
Check the price per 100g of actual protein, not just the tub price. A $60 tub with more protein often beats a $40 one.
How the live ProteinPrice Value Score is calculated
Body Science High Protein ranks 1 on this list with a perfect 10/10 value score. At $4.51 per 100g, it's the most cost-effective option at Chemist Warehouse right now. The 720g tub is a decent mid-size option, not too committed if you want to try the caramel honeycomb flavour first. It's not on sale, so this is standard pricing you can rely on.
Musashi Bulk Protein ranks 3rd on this list at $44.99 for 900g. At $5 per 100g, it sits in mid-range territory rather than budget-friendly. The value score of 3.3 out of 10 reflects its position as a recognisable brand with decent availability, but you're paying extra for the Musashi name. If you're chasing the absolute cheapest protein, there are better options higher up this list.
Musashi High Protein Powder ranks 5th on this list at $47.39 for 900g. At $5.27 per 100g, it sits in the mid-range for value. The vanilla flavour is a safe choice if you're after something versatile for shakes and smoothies. It's not the cheapest option here, but Musashi has solid brand recognition in Aussie gyms and chemists. Worth considering if you prefer sticking with familiar names over budget alternatives.
