No. All Australian whey is produced without rBST because it is banned nationally. Chief's additional step is batch-level testing that verifies the standard was met in each production run. The hormone-free status is shared; the verification is Chief's.

Hormone and antibiotic testing # Hormone and antibiotic testing in whey: what Australian standards cover and what Chief verifies If you are looking for whey protein free from added hormones and antibiotics, the starting point in Australia is the regulatory baseline. Australian dairy does not permit the use of rBST (recombinant bovine somatotropin) or rBGH (recombinant bovine growth hormone). These are banned at the national level, not by individual brands. Chief tests every batch for hormones and antibiotics as a verification step, confirming that the standard is met in practice, not claiming a unique exemption that other Australian dairy does not share. ## The science of hormone and antibiotic testing ### Short answer Australian dairy is produced without rBST and rBGH by law. Every Australian whey protein, not just Chief's, is free from these added growth hormones. Chief's batch testing verifies this standard is met in practice and extends to antibiotics and unwanted additives. The testing is a transparency measure, not a differentiator from other Australian dairy products. ### What the Australian standard covers Australia banned rBST in dairy production. The Australian Pesticides and Veterinary Medicines Authority does not approve it for use. This means no Australian dairy farmer can legally administer rBST to increase milk production. The ban applies to all Australian dairy, not selectively to premium or organic producers. Antibiotic use in Australian dairy follows strict withholding periods. If a cow receives antibiotics for illness, its milk is excluded from the supply chain until the withholding period clears. Bulk milk is tested for antibiotic residues before processing. These controls are regulatory, not voluntary. ### What Chief's testing adds Chief tests every batch of whey protein for hormones, antibiotics and unwanted additives. This does not create a hormone-free product that other Australian brands lack. It creates a verification layer: documented evidence that the regulatory standard was met in the specific batch you are consuming. The value of batch testing is traceability and accountability. If a contamination event occurred anywhere in the supply chain, batch testing would catch it. For consumers who want to verify rather than trust, the testing provides that confirmation. ### How to read hormone-free claims When an Australian whey brand says "hormone free" or "no added hormones," it is stating the Australian baseline, not a brand-specific achievement. The claim is true but not unique. Where a brand adds genuine value is in the testing: can they show you batch-level verification? Chief can. Many brands making the same claim cannot. When an imported whey brand from the US or South America says "hormone free," the claim carries different weight because rBST is permitted in those markets. In that context, the brand is choosing to exceed a lower baseline. The context matters when comparing claims across markets. ### How to use it Production standards do not change how a product is used. Chief whey is 30 g per serve, which is four heaped tablespoons, shaken or blended into water or milk. Chief collagen is 15 g per serve and dissolves in hot or cold liquid. The organ capsules are four a day, best in the morning. If hormone and antibiotic status is what you are buying on, the useful habit is to read the product page and label of each item rather than relying on a general brand statement, and to accept that a production claim says nothing about how much protein, iron or B12 you personally need. These are foods and food supplements, not treatments. If you are pregnant, breastfeeding or managing a health condition, get individual advice before adding any supplement. ## Not suited for Not suited if you are looking for a unique Chief exemption from hormones or antibiotics. The hormone-free status comes from the Australian regulatory standard, not from Chief specifically. Chief's value-add is batch-level verification, not a different product. Whey contains dairy and is not suitable for vegans, vegetarians or people with a dairy allergy. ## Chief Nutrition products for hormone and antibiotic testing  ### Grass-fed Whey Protein Powder, Smooth Chocolate Grass-fed whey protein concentrate in smooth chocolate, 22g protein per serve.
