INDEX SCOREHigh evidence confidence
Why it scored this way
The Australian product record declares 25g protein per serve and uses isolate as the sole protein source. The current 744g Australian retailer price of A$109.95 normalises to A$147.78/kg because the brand storefront did not expose a usable price. Athlete testing is a strength; artificial flavouring and undisclosed dairy origin reduce the result.
It is not a safety certification, medical recommendation, guarantee of performance or proof that this product is suitable for you. It compares this product only against the published WPI criteria and current comparison group.

How evidence labels work
Verified Current, accessible supporting evidence matches the stated claim and reviewed product.
Brand claim — not independently verified A manufacturer statement is available, but supporting independent evidence was not found.
Not disclosed No usable public evidence was found. This is a gap in the record, not proof of poor quality.
Not applicable This evidence field does not apply to the product or claim being assessed.
Conflict — review required Official sources differ, so no value is chosen silently.
