Grenade .50 Calibre

by Grenade

GMP Informed Sport Third-Party Tested

Grenade .50 Calibre is a high-stimulant pre-workout from the iconic UK brand known for its grenade-shaped packaging. Delivering 200mg caffeine per serving alongside citrulline, beta-alanine, and electrolytes, it targets gym-goers wanting strong energy and focus. Grenade's brand recognition across UK retail makes it one of the most visible pre-workouts on the high street.

AI Review Summary

Grenade .50 Calibre benefits from strong UK brand recognition and a generous 50-serving tub. The 200mg caffeine provides dependable energy, and the formula covers the basic pre-workout bases. However, citrulline and beta-alanine doses fall short of clinical thresholds, and the price premium over better-dosed competitors like Bulk Complete is hard to justify on formulation alone. Solid but not exceptional.

Clean Label Analysis

Fairly standard formulation with sucralose and artificial flavouring. Citrulline at 4g and beta-alanine at 2g are both below clinical doses. The inclusion of coconut water powder for electrolytes is a nice touch but at 500mg the dose is largely symbolic.
