Whey protein is a complete protein with all essential amino acids. The 500g size gives only ~16 servings, making cost-per-serving higher than bulk formats.

Consumer advice
Whey protein is one of the few supplements with genuinely strong evidence behind it — this is a real, useful product. IronMaxx is a reputable German brand. However, the 500g bag is a trial/starter size. If you use protein powder regularly, compare the per-kg price against Myprotein, Bulk Powders, or Foodspring, which often run significant discounts. Check the label for protein content per serving (aim for 20–25g per scoop) and whether it's concentrate or isolate (isolate is lower in lactose and fat). No red flags here — just shop around for the best price per gram of protein.
