Our verdict
Grenade wins — but USN is no pushover
Same-size bars, clear result: Grenade scores 84/A against the Trust Crunch's 74/B. Per 60g bar that's 21.6g vs 19.8g protein, and Grenade does it for 206 calories vs 213. Sugar is a wash (1.5g vs 1.6g per bar), and Grenade carries a verified Clean Score of 95 — USN's ingredients list isn't verified in our catalog yet.
The Trust Crunch isn't embarrassed: 33g protein per 100g and under 3g sugar is a genuinely good bar, and the triple-chocolate crunch texture has loyal fans. It's just up against the best mainstream bar in the UK.
Buy USN if the crunch texture or the flavour range is your thing — you lose ~2g protein per bar, not a catastrophe. Buy Grenade if you want the best numbers in the aisle.
