Optimum Nutrition Gold Standard PRO Gainer – High Calorie Mass Builder
Optimum Nutrition Gold Standard PRO Gainer is a premium high-calorie weight gainer designed to support serious muscle growth, recovery, and overall mass-building goals. Perfect for hard gainers and athletes with high calorie demands, this advanced formula delivers a powerful combination of quality protein and performance carbohydrates to help you grow stronger and recover faster.
Each serving provides approximately 650 calories, including 60 grams of high-quality protein to support muscle repair and maintenance. The formula also contains 81–82 grams of carbohydrates, helping replenish glycogen stores after intense workouts and fuel your next training session. Whether used post-workout or between meals, PRO Gainer makes it easier to meet your daily calorie and macronutrient targets.
Compared to Gold Standard Gainer, the PRO Gainer version offers a slightly lower calorie and carbohydrate profile, while delivering a higher protein dose per serving — making it ideal for those who want to prioritise lean muscle growth without excessive carbs.
