Consumer advice
If you're new to creatine, this is a solid choice — NSF Certified means it's tested for purity and banned substances. However, if budget is a concern, generic creatine monohydrate from reputable brands (Optimum Nutrition, Bulk Supplements) delivers identical results at 1/3 the price. Standard dosing: 3-5g daily (no loading phase needed, though some prefer 20g/day for 5-7 days to see faster results). Take with food and stay hydrated. Not suitable if you have kidney disease — consult a doctor first."
