For serious weight gain, mass gainer proteins are worth considering, but be careful—they often contain extra carbs and fats to boost calories, which can lead to unwanted fat if you’re not active enough. Look for a clean formula with at least 20-30 grams of protein per serving and a decent amount of calories (around 150-200 per scoop). Brands like Optimum Nutrition, Dymatize, and Naked Nutrition offer reliable options without unnecessary junk. The key is consistency—pair your protein with a balanced diet and strength training to see real results.
