Whey Protein Isolate Sample Pack

Wondering where to buy protein powder in Australia? New to Bulk Nutrients? Try our delicious Whey Protein Isolate flavour range today!

Our WPI is one of the purest on the market, it is ultra-high in protein, low in carbs and fat, and is certified as being sourced from grass fed, hormone free cows.

A Whey Protein Isolate Sample Pack contains a random assortment of flavours which can include:

  • Chocolate
  • Vanilla
  • Banana
  • Choc Honeycomb
  • Peppermint Slice
  • Cookies & Cream
  • Strawberry
  • Salted Caramel
  • Choc Peanut
  • Iced Coffee

Actual flavours included depend on current stock levels and cannot be guaranteed.

A Whey Protein Isolate Sample Pack is incredibly handy, perfect for gym bags, and as a convenient on-the-go high protein snack instead of lugging around a whole bag of protein, or you can use them as a back-up supply of protein.

They are also a great way to try all the delicious WPI flavours. Once you’ve tried the range of flavours and you know which ones are your favourite, grab a 1kg bag of Whey Protein Isolate for $40 with further price breaks up to 20kg, meaning you save more when you buy in bulk!

For full directions, ingredients and nutrition panels, please refer to the main WPI product page.

Whey Protein Isolate Lab Testing Results

At Bulk Nutrients we take our products’ purity very seriously.

To maintain our Whey Protein Isolate’s consistent high quality, we send a cross section of our product range away to be tested for protein purity by the National Measurement Institute (NMI) each month.

The NMI is a laboratory run by the Australian Government, which is used for police forensic testing, SIA - Sports Integrity Australia drug screening and by multinational food manufacturers for quality and safety testing.

NMI has conducted many hundreds of tests on Bulk Nutrients products for more than 6 years.
