At Bulk Nutrients, we take our products’ purity very seriously.
To maintain our supplements’ consistently high quality, we regularly send protein samples within our product range to the National Measurement Institute (NMI) (Australia’s Government Laboratory) for protein testing and share the results with you. For you it means we back our principle of delivering Australia’s purest supplements at the most affordable prices. Please explore our lab tests, through these links you’ll find over 250 lab tests showing the consistency of our protein product over many years. You’ll find only small variations with all tests within a 3% margin, mostly due to seasonal variations.
"Please note we utilise the services of BIOTEST Laboratories QLD for all purity testing of raw ingredients such as amino acids. Biotest Laboratories are NATA accredited and are utilised by the Australian Government and the TGA for testing of ingredients. These tests are all within 1% of manufacturers COAs."
latest Lab Test Results
Each month we update this page with our latest results, so you can transparently see how pure our proteins are. Occasionally you may see our proteins out of specification within a 3% margin, due to natural seasonal variations in milk. On our packaging we join the other companies in the industry and state the best case scenario when detailing our nutritional information.

How does lab testing set Bulk Nutrients apart from the rest?
While some companies occasionally offer lab testing, here at Bulk Nutrients we have always prioritised regular testing to ensure we can show that our products have been consistently tested and that our claims about our products are legitimate.
Every month at least 4 of our proteins are lab tested for protein percentage - this is in addition to all the microbiological testing we do to ensure the safety of the food products we produce.
These protein tests show we consistently have results to back up our protein claims. We continue to do these tests as it allows us to show our dedication to quality and ensures we are constantly delivering the public the purest products possible.
All Bulk Nutrients lab testing reports includes a product name, flavour, batch number and used by date.
Identifying every test conducted means customers receive the same products which are lab tested. While not every batch is lab tested, it demonstrates we continually test a thorough cross section.
We want customers to be completely assured, our products which are tested are the same ones they are purchasing.
History of testing
While frequency is important, the length of time our testing has occurred for is important. Bulk Nutrients protein quality lab tests have been regularly occurring for more than 6 years which is why you can see lab test reports which go back to 2014 and earlier on various products.
This combination of disclosure, frequency and a lengthy history of lab testing is unique to Bulk Nutrients.
How are your lab tests done?
The lab tests of our proteins are all done the same way:
After our production team make a run of product our finished products are all transferred to our holding and dispatch areas at Bulk Nutrients.
Our Quality Assurance manager (who has almost 30 years experience in the dairy industry) then takes a random bag off the shelf into our internal laboratory and separates a 30g sample in a sealed container. They complete the paperwork which matches the sample with its manufacturing date, batch number and other details.
The sample/s are sent to NMI laboratories (NATA accredited lab) with the enclosed paperwork, via Australia Post.
Once the samples are received, NMI transfer the paperwork details into their system and tests the sample. They use the industry standard Kjeldahl test which measures the total nitrogen of the product.
A multiplication is then conducted dependent on the type of protein tested; the result is a value for the total protein level.
This is the same system used by dairies and manufacturers of the raw product and is considered the industry standard for protein testing.
Why is "as is" the correct way to display the results, rather than "dry basis"?
"As is" is a protein test which measures and verifies the protein level "as is" ie exactly how you receive it. This is the form which includes some moisture and whatever fats and carbohydrates are naturally present. It is important to note all our protein testing is done this way.
We understand that some companies quote "dry basis" for their products for protein levels and lab tests, which is not consistent with FSANZ standards. Quoting "dry basis" raises the protein level of the test and inflating the number, something we consider to be misleading.
If we quoted "dry basis" all our products would appear to be 4-6% higher in protein, so keep this in mind if comparing to a competitor’s lab test – or if they suggest "as is" shows far lower than their labels state (it shouldn’t).
How regular are your lab tests?
Our lab tests are done several times a month, with protein tests done at least once a month.
Our lab testing is far more thorough than just protein verification, we regularly test for microbiological levels and other factors which demonstrate our products comply with all health and safety standards. It is the protein testing we tend to talk more about as it interests customers.
How do I know the results you publish are accurate?
By publishing an extensive history of lab testing over many years where every product tested is properly identified, we feel we demonstrate this well.
Bulk Nutrients history of testing shows a pattern of accuracy and by using the same test methods and the same NATA accredited Gov lab (NMI) it is very consistent.
We also offer customers the opportunity to test our products too by sending samples directly to NMI laboratories. Customers and non-customers can utilise the same testing service to verify any brand of product they purchase – unless we already have plenty of data on that brand.
Why do the results on your website do not always match your claimed specs?
Virtually all of the lab tests displayed on our website are within 3% of the claimed spec, which we have evaluated is a high level of accuracy. If products fall outside of this, we take action to rectify the issue whether it be label updates or thorough checks on the raw goods going into the product.
Numbers can be down due to a change in supplier, a minor recipe adjustment or less likely a case of seasonal condition changes with raw stock. Seasonal changes do affect protein percentage but these are minor.
It should be noted that all our declared protein levels are "best case" so its very rare the test results would exceed what we list. If recipe changes or raw good changes affect the nutritional panel of a product, these are always updated in a timely fashion.
How do your amino acid tables fit in and are these always accurate?
Amino Acid tables are complex! The amino tables we display are provided by the manufacturers and curiously they rarely add up to the actual protein level. If you look carefully, most are based on "100g of actual protein", rather than "100g of protein powder" (protein powders are 75% to 90% protein).
Dairies and raw manufacturers provide their amino tables based on averages, so these are not regularly tested. We recommend people use these as a guide and realise they are protein type specific and not brand specific.
Ie, Whey from any brand will always have higher BCAA levels than plant proteins, Collagen will always have far higher Glycine levels than other types of protein. The exception to this is when companies add amino acids separately to their proteins to boost certain values.
Basically, once you have selected the type of protein you want, the amino acid levels of that product will almost always be relative to its total protein. Ie, if Bulk Nutrients WPI is 3% higher than another brand it will likely contain 3% more leucine, valine and phenylalanine (and other amino acids) as total protein is a combination of all the amino acids present.
If you want to compare one companies WPI to another, stick to the protein level on the nutritional panel. If you want to compare which type of protein you want to buy, ie casein, whey, collagen, compare the amino acid tables to each other using the same company's website.
How can I have a product lab tested?
As our own research indicated many companies were severely under dosing their proteins, we decided to offer a service where consumers could send a sample of any protein they’ve purchased directly to NMI lab testing for verification.
This has helped hundreds of Australian consumers know whether they have been buying accurately labelled protein, a service that no other company has ever offered.
If you would like your protein lab tested, you will need to do the following:
- Contact us at firstname.lastname@example.org
- Ensure the protein you want tested was purchased by yourself and guarantee you’re the only one to use the protein purchased
- Take photographs of all packaging/batch identification and proof of purchase for records
- Isolate at least a 30 gram sample of the protein you want tested and identify it
- Fill in and sign a declaration (which we will provide) which includes when and where your protein was purchased, and a guarantee has not been tampered with in any way
- Fill in some basic paperwork and send the sample of protein with your paperwork to NMI laboratories directly
Sounds complex but it really isn’t. We’ve devised this process over many years of testing as it’s the best way to ensure you receive accurate results.
You’ll note in the process above that we ask you to send the samples directly to the NMI laboratories – this is done to ensure there’s no mixups and the sample cannot be tampered with.
NMI laboratories normally contact us with the lab report within 1-2 weeks of receiving the sample which we send this onto you as is.
