Consumer advice
If you're interested in EAA supplementation, this product is safe and transparent—but consider whether you actually need it. Most people eating adequate protein (0.8–1g per pound of body weight) from whole foods get sufficient EAAs without supplementation. If you do supplement, compare this to bulk EAA powders (MyProtein, Optimum Nutrition, Bulk Supplements) which offer 5–10g per serving at $0.50–$1.50 per serving. The capsule form here is convenient but expensive. For muscle growth, combine any EAA supplement with consistent resistance training—the supplement alone won't build muscle without exercise. Check the expiration date on your bottle (one reviewer noted an EXP:01/25 on a recent purchase)."
