FAQ
Product comparison, answered.
Which is cheaper today, Blackbelt Platinum Protein or Pure Product Whey Protein Concentrate / Isolate?
Blackbelt Platinum Protein is cheaper today at $47.64/kg of protein — 10% less than the other option. Prices are scraped daily across every Australian retailer we track, so the verdict can flip overnight.
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.
