Where is each brand's whey sourced?

Chief uses Australian grass-fed dairy. True Protein uses New Zealand grass-fed dairy, blended and made in Australia. Both are grass-fed, so the only real difference is the country the milk comes from, which matters to some buyers and not to others.

Is either one HASTA certified?

Neither whey concentrate is HASTA certified. True Protein does sell a separate HASTA-certified WPI90 isolate for drug-tested athletes. Chief does not hold HASTA on any product. If you compete under testing, look at the HASTA isolate or another certified option.

Do they add sweeteners?

Chief's unflavoured tub has none, and its flavoured tubs use monk fruit. True Protein's Natural is unsweetened, and its flavoured tubs use natural sweeteners with no added sugar. Both avoid sugar alcohols, so both flavoured lines are clean.

Which has more flavours?

True Protein, by a wide margin. It offers nine flavours plus a Natural option on the WPC80. Chief's whey comes in unflavoured, chocolate and vanilla. Both keep a plain option for those who want it.

Do they suit vegetarians or vegans?

Neither suits vegans, since whey is a dairy protein. Both suit vegetarians. If you are lactose sensitive, a concentrate holds more lactose than an isolate, so start with a small serve.

Chief vs True Protein Whey: An Honest Comparison

Q: Is Chief or True Protein whey better?

On the ingredient they are very close. Both are premium grass-fed whey concentrate at about 80% protein. Chief is Australian grass-fed and minimally processed in a clean unflavoured tub; True Protein is New Zealand grass-fed and ultra-filtered, cheaper and in more flavours. Chief edges it on minimal processing and a clean unflavoured tub, but it is a close call. It comes down to sourcing and processing against price and flavour.

Q: Which one is cheaper?

True Protein. Its WPC80 is $78 a kilogram against Chief's roughly $111, or about $9.75 a 100 grams of protein against about $14. Both are premium grass-fed concentrates, so it is a like-for-like saving.

On the ingredient there is little between them: both are premium grass-fed whey concentrate at about 80% protein. Chief is Australian grass-fed, minimally processed and clean unflavoured; True Protein is New Zealand grass-fed and ultra-filtered, cheaper and in nine flavours. Chief edges it on minimal processing and a clean unflavoured tub, but this is a close call, not a blowout, and neither concentrate is HASTA. Pick on sourcing and processing against price and flavour choice.

At a glance

Start with what is in the tub, and on that these two are genuinely close: both are premium grass-fed whey concentrate at about 80% protein and a 24 gram protein serve. The differences are narrow. Chief's dairy is Australian grass-fed and minimally processed, in a clean unflavoured tub. True Protein's is New Zealand grass-fed and ultra-filtered, blended and made in Australia. It is cheaper, $78 a kilogram against Chief's roughly $111, which is about $9.75 a 100 grams of protein against about $14, and it comes in nine flavours plus a Natural. Neither concentrate is HASTA certified, though True Protein sells a HASTA isolate elsewhere in its range. Chief edges it on minimal processing and a clean unflavoured tub, but that is a small margin, not a blowout. If price and flavour choice decide it, True Protein wins; if you want Australian-sourced dairy and minimal processing, Chief is the pick.

The cost, in full

All prices are AUD, read from each brand's own site on 6 July 2026. Both are grass-fed whey concentrate at about 80% protein and a 30 gram serve, so the fair yardstick is price per gram of protein. Chief's 900g pouch is $99.95, about $111 a kilogram or about $14 a 100 grams of protein. True Protein's WPC80 is $78 a kilogram, about $9.75 a 100 grams of protein, a real saving across two closely matched premium products.

This is a point where Chief is the dearer option, and it is worth saying plainly. You are not getting more protein per serve from Chief. The extra pays for Australian-sourced dairy, minimal processing and the Chief range, where True Protein's dairy is New Zealand grass-fed and ultra-filtered. Whether that premium is worth it depends on how much Australian sourcing and minimal processing matter to you.

Where Chief is the better choice

You want Australian grass-fed dairy

This is the clearest difference between them. Chief's whey comes from Australian grass-fed dairy cows, start to finish. True Protein's is New Zealand grass-fed, then blended and made in Australia. Both are grass-fed and New Zealand dairy is well regarded, so the split is simply the country the milk comes from. If Australian sourcing is what you are after, Chief is the one that has it.

You want minimal processing and a clean tub

Chief's unflavoured whey is just the concentrate, minimally processed with no sweeteners or fillers, and it sits in a wider clean range alongside collagen, creatine and beef. True Protein is ultra-filtered and makes a clean product too, so this is a narrow edge rather than one being far cleaner than the other. Minimal processing is chosen to hold on to more of the bioactives that heavier filtering can strip, and if you value that and want your protein from the same whole-food brand as the rest of your order, Chief is the fit.

You prefer monk fruit on flavoured protein

Chief's flavoured whey tubs are sweetened with monk fruit. True Protein's flavoured tubs use natural sweeteners too, with no added sugar, so both steer clear of sugar alcohols. If monk fruit is specifically your preference, Chief is the one that uses it, though this is a small point and both brands keep their flavoured tubs clean.

Where True Protein is the better choice

You want the lower price

For the same amount of protein, True Protein costs less. Its WPC80 is $78 a kilogram against Chief's roughly $111, about $9.75 a 100 grams of protein against Chief's about $14. Both are premium grass-fed concentrates, so this is a real saving on a like-for-like product rather than a cheaper substitute. If price is the deciding factor, True Protein wins.

You want more flavours

True Protein offers nine flavours plus a Natural option on its WPC80, where Chief's whey comes in three: unflavoured, chocolate and vanilla. If you like variety or rotate flavours through the week, True Protein simply has more to choose from. Both keep a plain, unsweetened option for anyone who wants it.

You want New Zealand whey or a HASTA option

True Protein's WPC80 is New Zealand grass-fed, which many in the industry rate highly. The WPC80 itself is not HASTA certified, but the brand sells a HASTA-certified WPI90 isolate for athletes who need banned-substance testing. Chief does not hold HASTA on any product. So if New Zealand sourcing or a HASTA option in the same range matters, True Protein has both.

Sourcing and range: what differs

Both are premium grass-fed clean whey concentrates, so the ingredient is very similar and the differences are narrow but real. Chief's dairy is Australian grass-fed and minimally processed, and its whey sits in a wider clean range alongside collagen, creatine and beef. True Protein's is New Zealand grass-fed and ultra-filtered, blended and made in Australia, and it comes in far more flavours at a lower price, with a HASTA isolate available elsewhere in its range. Neither is cutting corners. Chief edges it on minimal processing and a clean unflavoured tub, and from there it comes down to whether Australian sourcing and the Chief range outweigh True Protein's price and choice.

Before you buy

Whey does not suit everyone, and this applies to both brands. It contains dairy, so it is not for anyone with a milk allergy, and it does not suit vegans. A concentrate holds more lactose than an isolate, so if you are lactose sensitive you may still react to it, and an isolate or a non-dairy protein may sit better. Whey is a food, not a treatment, and it works alongside training and a sound overall diet rather than replacing them.
