Overview
BSN Supplements Syntha-6 is a whey blend that SuppSaver compares across 2 Australian retailers. The best price we're currently tracking is $256.45 at Supplement Warehouse, which works out to $12.02/100g protein — the true-cost figure we rank every whey protein on. That comes to roughly $2.64 per serve. At 50% 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 nightly and rank by true cost per 100g of protein rather than sticker price. That lets you see whether Syntha-6 is genuinely the cheapest whey protein on the market or simply discounted right now. It's listed in 4.3kg, 2.1kg and 1.3kg. Shoppers rate it 4.7 out of 5 from 21 reviews. Use the price history, the per-store breakdown and the alternatives below to confirm you're getting the best deal before you buy.
