Anyone can print a number on a tub. We can show you where it came from. Every claim on this page traces back to a real document: the Fonterra batch our whey was made from, the independent test on every batch we pack, and the audited plant where it’s made.
Transparency shouldn't be a tagline, it should be a paper trail. Here’s what sits behind every tub of Xplosiv NZ Whey.
Every batch is independently lab-tested for protein content, heavy metals, contaminants and 250+ banned substances. We’re publishing the results here, batch by batch. Not the first batch. Every batch.
Take any batch: our whey traces back through our production records to a single Fonterra batch. The same reference numbers appear across independent documents, ending in Fonterra’s signed Certificate of Analysis.
Blended and packed at VitaLabs, a New Zealand-owned GMP facility in Auckland, independently audited by SGS and AsureQuality to GMP-NZ, HACCP and MPI standards.
We used to test protein content on selected batches. Now every batch is independently tested across a full panel, and we’re publishing the Certificate of Analysis here, batch by batch.
Verified against the number on the label, within normal analytical variation, and on file for every batch.
Screened for lead, cadmium, arsenic and mercury, including contaminants that can come from added ingredients.
Microbiological and contaminant screening on the finished, blended and packed product, not just the raw whey.
HASTA certified - each certified batch screened against the WADA Prohibited List and publicly listed.
Independently tested by Eurofins (IANZ-accredited lab) using ISO 8968-1 (Kjeldahl, N×6.38), the reference method, against a label claim of 25 g per 30 g serve (83.3 g/100g). That’s inside our ±5% tolerance, for this exact batch.

Every batch of our NZ Whey and NZ Isolate is listed on HASTA’s public certified register, verified independently, not by us.
NZ Whey results are in: see every batch in the Open Book. Natural NZ Isolate is next.
Check our batches on HASTAAdded ingredients like cocoa can carry their own contaminants, so heavy-metal and contaminant testing is done on the final product, after blending and packing. That’s where it counts.
Given what’s happening across the supplement industry right now, we moved fast - because that’s what this brand is built to do. This testing section is live and updated in real time. We’d rather get it in the open now, incomplete, than wait until it’s polished.
And if something’s not right, we’ll say so. Good or bad, the numbers go up. If something’s off, we’ll own it and fix it. Publicly. No exceptions.
Made at VitaLabs in Auckland under a controlled, signed-off production system, where every step is checked and signed before a batch is released.
Every incoming raw material is assigned its own unique Inwards Goods (IG) number. Nothing enters production unlabelled.
Best-before dates and batch numbers are recorded on arrival, and a 50 g retention sample is kept so any batch can be re-checked later.
Dates and batch numbers are re-verified, the formulation is confirmed against the approved master formula, and hygiene and equipment checks are signed.
Blended in controlled sub-batches, then sieved for an even, consistent mix from the first scoop to the last.
Fill weights are checked throughout the run and held at or over target, never under. You get at least what’s on the label.
Seal, label, batch number and best-before are checked and signed. Any unit that fails is pulled and recorded as a reject.
A sample from every batch goes for independent lab testing: the Certificate of Analysis behind “tested every batch”.
Final yield is recorded and the batch is released only once every check is complete and signed off.
“NZ whey” should mean something. Here’s one batch, traced end to end. Every link is backed by a document, and every document shares the same reference numbers.
The incoming raw whey. This Fonterra ingredient certificate proves genuine NZ Fonterra whey, traceable to the exact batch. The finished tub is then tested separately (see Tested every batch).
Each reference appears on both the delivery paperwork and Fonterra’s certificate, issued independently of each other.
Our NZ Whey is blended and packed at VitaLabs, an Auckland GMP facility whose systems are independently certified and audited.
Independent auditor of the VitaLabs plant’s quality and food-safety systems.
