FAQ
Product comparison, answered.
Which is cheaper today, Blackbelt Whey Protein Concentrate or MyProtein AU Impact Lean Whey?
Prices are scraped daily across every Australian retailer we track. See the live comparison above for today’s cheapest option.
What does $/kg of protein mean?
It’s the price per kilogram of actual protein, not powder. We calculate it as: price ÷ (size_in_kg × protein_percentage). This controls for protein density — a $35 WPC at 75% protein is actually worse value than a $40 WPI at 90%, and $/kg of protein is the only number that captures that.
How is leucine calculated?
Leucine per serve is estimated from the protein subtype using established industry ratios: WPI ~12% of protein is leucine, hydrolysed ~13%, WPC ~10%, blend ~10%. So a 25g WPI serve delivers ~3g leucine. The 2.5g threshold is what research says you need per meal to maximise muscle protein synthesis.
