Read the two fields separately
The60g on the selected Grenade wrapper is the net mass of the food unit. Its selected nutrition panel declares21g protein per bar. The rest of the food mass is not described by calling the whole bar protein. Likewise,Fulfil55g is a bar mass with20g protein declared,and TREK50g is not50g protein.
Price per food mass
At£2.90 for60g,the Grenade ordinary quote is approximately£4.833333 per100g of food. That is useful for comparing the cost of a standard quantity of the product. It is not£4.833333 per100g protein. To discuss a protein-price metric at all,would require an unambiguous selected nutrient basis,clear rounding and a statement that it still is not nutritional value or personal suitability.
Why this site withholds a protein-price ranking
The TREK source has a9g headline and9.8g per-bar table,so a single common protein-cost ranking would hide a material unresolved field. Our tools support declared bar counts and net food-mass rates instead. The reader can inspect the source nutrition,but the site does not choose the most convenient protein figure to make an offer look cheapest.
A mass-target planning example
If a buyer’s own stock record is in whole wrapped bars,use the bar-count tool rather than dividing food grams by an assumed nutrient amount. A150g TREK multipack has three declared50g bars;that known count does not need to be reverse-engineered from protein. Unknown counts in another product would remain unknown even if its total net mass were known.
Keep the conclusion within purchase scope
The useful next decision is whether the actual pack size,ingredients,label and budget meet the chosen shopping brief. No conclusion about daily protein need,muscle gain,meal replacement or disease suitability follows from a net-weight comparison. We have not weighed the bars or measured their nutrient composition,and actual received panels remain the final record to check.
