If you want the most bang for your buck, skip the flashy marketing and focus on protein content per scoop. Look for powders with at least 20 grams of protein per serving and minimal fillers like added sugars or artificial junk. Store brands from Costco or Walmart often match the quality of big-name brands at a fraction of the price. Just check the label—sometimes the cheapest option is the best one if it fits your needs.
