Consumer advice
If you need NSF Certified for Sport status — because you're a competitive athlete subject to drug testing — Thorne's price premium is justified. If you're a recreational gym-goer, any third-party tested creatine monohydrate (Optimum Nutrition, Bulk Supplements, Nutricost) will deliver the same results for a fraction of the cost. Take 3–5g daily; no loading phase required. Mix with water or a carb-containing drink for best muscle uptake.
