Is CNP Professional a good brand?
CNP Professional is a long-standing British brand built around the bodybuilding scene, best known for Pro Whey (a fast whey blend) and Pro Peptide (a multi-stage protein for sustained release). It sits in the mid-price bracket: dearer than pure supermarket concentrate, cheaper than premium isolate-only brands. WheyWise tracks 10 CNP Professional products. The cheapest is £0.44 per 25g of protein on CNP LOADED ISO 1.8kg, ranging up to £1.17. Prices swing a lot between retailers, so the table below is worth checking before you reorder.

Frequently Asked Questions
How much does CNP Professional protein cost in the UK?
CNP currently ranges from £0.44 to £1.17 per 25g of protein across the UK retailers we track, with CNP LOADED ISO 1.8kg the cheapest right now. Every price in the table above is shown with the date it was checked.
What is the difference between CNP Pro Whey and Pro Peptide?
Pro Whey is a fast-digesting whey blend aimed at post-workout. Pro Peptide layers whey, milk and egg proteins for a slower, more sustained amino acid release, which some people prefer between meals or before bed. Per gram of protein, Pro Whey is usually the better value of the two.
Where is CNP Professional cheapest in the UK?
It varies week to week between Amazon UK, specialist supplement retailers and CNP's own store. The comparison table above normalises every option to cost per 25g of protein so you can see the genuine cheapest without checking each site.

Methodology
How we rank every bag.
Independent and transparent, with every price shown alongside the date it was checked. Here's what goes into each score.
01
Cost normalised to £/25g
Every bag divided by its true protein weight, so you see the real cost of a scoop across any size or brand.
02
Protein density, measured
Protein per 100g from the product's own nutrition panel, so a 90% isolate and a 72% concentrate are never compared on bag price alone.
03
Every price carries its date
Prices come from the retailer's own listing, never an RRP, and each one is shown with the day it was last checked so you can judge how current it is.
04
No sponsored placements
Rank order is cost per 25g of protein. Some outbound links earn commission; none of them buy a position in the table.
