Live prices
Looking for affordable protein at ASN without sacrificing quality? This comparison page shows protein powders available at ASN sorted by cheapest upfront price, current as of May 2026 and refreshed regularly. Right now, Switch Nutrition's Beef Protein Isolate starts from $19.95, making it the lowest entry point, while trusted options like Optimum Nutrition's Gold Standard 100% Whey come in at $44.76. When comparing different products and sizes, always check the cost per gram of protein rather than just the ticket price. A larger tub might cost more upfront but deliver better value per serve. The products below include whey, beef, collagen and custard-based proteins across various brands and sizes, so you can find what fits your budget and dietary preferences.
Check the price per 100g of actual protein, not just the tub price. A $60 tub with more protein often beats a $40 one with less.
How the live ProteinPrice Value Score is calculated
Switch Nutrition's Beef Protein Isolate ranks 1 on this list with an impressive 9.8 value score. At $19.95, it's genuinely cheap per gram of protein. The main trade-off is the tiny 120g size, so you'll be reordering frequently. It's a solid budget option if you don't mind buying in small amounts and want to try beef protein without commitment.
Muscle Nation's Custard Protein ranks 2nd on this list with a value score of 6.4 out of 10. At 18 cents per gram of protein, it sits in decent territory for budget-conscious buyers. The chocolate flake flavour offers something different from standard whey options. Main trade-off is the tiny 180g size, which means you'll be reordering frequently compared to bulk tubs. It's positioned as a novelty dessert-style protein rather than your everyday workhorse powder.
Musashi Bulk Protein ranks 5th on this list with a value score of 7.8 out of 10. At $5.15 per 100g, it sits in the mid-range for pricing at ASN. The 900g tub size is decent for testing a brand without committing to a massive container. Musashi is widely stocked across Australian retailers, so it's easy to grab in-store if you run out. Not the absolute cheapest option here, but solid value for a recognisable local brand.
