Consumer advice
Creatine monohydrate is one of the few supplements with genuinely strong evidence behind it, so this is a reasonable buy if you want a trusted brand. But since creatine monohydrate is a single, standardized molecule, cheaper bulk brands (Bulk Supplements, Nutricost, NOW Sports) deliver identical results for roughly half the per-serving cost. Check the actual supplement facts panel to confirm each scoop delivers 5g, and skip the subscription unless you're sure you'll use a tub every 30 days - one-time purchase avoids any auto-renewal hassle.
