daniel_trm 1.0I bought one from bulk nutrients and it is packed in Australia from zero percent Australian ingredients. Looks like it is now made from imported WPI and no longer made from Aus made WPI
True Protein is made from WPI sourced from New Zealand which has stricter food regulations and better quality milk in general. Bulk Nutrients is from imported WPI of unknown origin (most likely china) so cheaper, but not as high quality and healthy.
Dismal_Blueberry1510 1.0They never have sales, I've been buying WPI and Creatine from them for 10 years, 5kg at a time for a good price, always consistent quality and flavour
fulltimepleb 1.0Can anyone explain how True Protein is $89 for 1kg and Bulk Nutrients is $58? Both are WPI. I looked at the amino profiles and protein per scoop and it’s almost identical. They are both sourced from grass fed cows too. I only buy the unflavoured versions of protein so flavour choice isn’t a factor either. Why would anyone buy from True if you don’t want their specific flavouring? Am I missing something lol?
SpaceIsBigReallyBig 1.0You can get unflavored wpi powders too. Have a look at Bulk Nutrients wpi.
yoloed 1.0Isolate used to cost 38 a kilo 2 years ago if you bought it in bulk. Now it’s 60.
Aware_Breakfast5770 0.5Muscle nation shakes vanilla is pretty nice get them at Cole’s/woolies, ehp labs oxyshred, bulk nutrients most affordable and great value
BoysenberryAlive2838 0.5Dismal-Debate-7693 0.5Im a big fan of bulk nutrients taste but always check the specials at Chemist Warehouse and often get their more expensive brands a little bit cheaper than BN If you're using isolate I'm not sure. I switched to concentrate without issues for price reasons years ago
hautepotato 0.5INC at chemist warehouse is now usually my go to. I always wait for sales (there’s one currently) so it’s approx $30-35 a kilo for WPC (their “dynamic whey”). I don’t find it necessary to shell out for WPI. I used to use Bulk- the only downsides now are having to wait for sales, and storing giant tubs not bags. Sales are pretty frequent though, I just buy 2 2kg tubs at a time.
