Grass Fed WPI

Pillar Performance Grass Fed WPI is a whey isolate that SuppSaver compares across 3 Australian retailers. The best price we're currently tracking is $118.70 at Supplement Warehouse, which works out to $14.93/100g protein — the true-cost figure we rank every whey protein on. That comes to roughly $3.96 per serve. At 80% protein by weight, the cost per 100g of actual protein — not just powder — is what decides whether it's good value.

Retailer prices shift week to week, so we re-check every listing daily and rank by true cost per 100g of protein rather than sticker price. That lets you see whether Grass Fed WPI is genuinely the cheapest whey protein on the market or simply discounted right now. It's listed in 1kg. Shoppers rate it 5.0 out of 5 from 2 reviews.
