Great flavour has always been at the heart of our Whey range. Now there’s even more assurance behind what’s inside the tub, with independent testing and verification through the Informed Protein programme.
For you, the message is simple: the protein stated on the label has been independently checked against the product.
What is Informed Protein?
Informed Protein is a global quality assurance programme for protein supplements, designed to give consumers greater confidence in the products they’re buying.
Certified products undergo independent testing to verify that the protein stated on the label matches what’s actually in the product.
The programme also goes beyond protein quantity, with checks around protein integrity, contaminants and manufacturing quality.
What does this mean for Per4m Whey?
It means another level of independent assurance behind one of the most important numbers on a protein product: how much protein you’re actually getting.
- Protein level verified: the protein stated on the label is independently checked against the product.
- Protein integrity assessed: testing looks for undeclared amino acids that could affect protein measurement.
- Quality checks: certified products are assessed for heavy metals and pesticide residues.
- Manufacturing reviewed: manufacturing processes are assessed against Informed Protein quality standards.
- Ongoing verification: certification includes continued testing after the initial certification process.

Why did we choose to get certified?
Because what we put on the label should be backed by what’s inside the product.
We chose Informed Protein certification to give you greater transparency and confidence in the quality, accuracy and consistency of our Whey range.
Independent verification adds another layer of assurance alongside what Per4m Whey is already known for: great taste, a huge choice of flavours and protein that’s easy to make part of your everyday routine.
Regularly tested. Independently verified.
Informed Protein certification isn’t based on a logo alone. Certified products undergo regular testing as part of the programme, helping verify protein label claims on an ongoing basis.
The official Informed Protein certified brands directory provides an independent place to view brands and products covered by the programme.
