If you're in Caroline Springs and searching for gluten-free protein powder, here's what actually matters when you're buying online rather than picking something off a supermarket shelf without checking the label properly.
Why 'gluten-free' needs checking, not assuming

Gluten-free claims in Australia are governed by Food Standards Australia New Zealand (FSANZ) — a genuine gluten-free claim means the product contains no detectable gluten, not just that wheat isn't a headline ingredient. Cross-contamination during manufacturing is the usual reason a product that looks gluten-free on the ingredient list still isn't safe for someone managing coeliac disease or gluten sensitivity.
What GC Proteins states

GC Proteins carries a Gluten Free badge on-pack, built on a pea, rice and faba bean protein blend that is naturally gluten-free by ingredient — always confirm current certification status directly on the pack you receive, since claims and standards can be updated.
Ordering to Caroline Springs

• Standard shipping typically reaches outer Melbourne suburbs within a few business days of dispatch — check current delivery estimates at checkout for the most accurate timing.
• Ordering online avoids the limited gluten-free protein range typically available at local Caroline Springs supermarkets and pharmacies.
• A Sample Pack is a low-commitment way to confirm the taste and texture work for you before committing to a full-size tub.
What to check before you buy, wherever you're shopping

Whether you buy from GC Proteins or elsewhere, check the gluten-free claim is explicit on the label (not implied), check the full ingredient list yourself, and if you manage coeliac disease specifically, look for products manufactured in dedicated or well-controlled gluten-free facilities.
