Consumer advice
Creatine monohydrate is genuinely effective at 3-5g/day, and this product delivers exactly that with no proprietary blend nonsense. If you're a tested athlete, the NSF Certified for Sport label justifies some premium over generic tubs. If you're not competing under drug-testing rules, a cheaper creatine monohydrate (Creapure or plain micronized) from any reputable brand will do the same thing for roughly half the price per serving.
