FAQ
On a $/kg-of-actual-protein basis, Maxs is cheaper right now. Maxs's cheapest in-stock product works out to $68.25/kg of protein, vs Optimum Nutrition's $75.31/kg. Prices are re-scraped daily, so the answer can change overnight.
We pull the best in-stock price for every product from each brand across every Australian retailer we track, then convert each to a single $/kg-of-actual-protein figure using the formula: price ÷ (size_grams × protein_percentage / 100 / 1000). That controls for protein density, so a $35 WPC at 75% protein and a $40 WPI at 90% protein are compared apples-to-apples. Full methodology on the methodology page.
