Ingredients
Creatine Content
ON Gold Standard includes a solid 3g of creatine monohydrate, which is a genuine performance benefit. Grenade .50 Calibre includes creatine but hides the dose behind a proprietary blend, making it impossible to know how much you are getting.
Caffeine & Stimulants
ON delivers 175mg of caffeine with full transparency. Grenade uses a proprietary blend approach, so the exact caffeine content isn’t confirmed — our estimate based on effects is around 200mg. If knowing exactly what you’re consuming matters to you, ON wins by default.
Taste
Both products taste decent. ON Gold Standard’s Fruit Punch and Green Apple are solid. Grenade offers unique options like Killa Cola and Berry Blast. Neither will win any taste awards against Ghost or ABE, but both mix well and go down easily.
Value
Grenade is slightly cheaper per serving, but ON Gold Standard delivers more transparency and verified ingredient doses. Penny for penny, we think ON represents better value because you know exactly what you’re paying for.
Verdict
ON Gold Standard is the better buy. Its open-label formula, solid creatine dose, and trusted brand make it a reliable choice. Grenade .50 Calibre isn’t bad, but the proprietary blend is a dealbreaker for informed buyers. See both ranked in our beginner pre workout guide.
