                                Many athletes find it challenging to consume the significant number of calories required to support intense training and muscle growth through whole foods alone. This is precisely where a professional weight gain supplement, or pro gainer, steps in, providing a concentrated and strategic dose of protein, carbohydrates, and healthy fats. Unlike standard mass gainers, a pro gainer is formulated for experienced individuals focused on building lean muscle mass with minimal fat gain.
