The Bulk Protein Company, SERIOUS GAINZ - Whey Protein Powder - Weight Gain, Mass Gainer - 30g Protein Powders (Chocolate, 5kg)
HIGH-CALORIE MASS GAIN FORMULA WITH ~27G PROTEIN PER SERVING – SERIOUS GAINZ by The Bulk Protein Company delivers approximately 460 calories, 27g protein and 74g carbs per serving, helping support a consistent calorie surplus. Designed for hardgainers and anyone looking to increase size and strength, it supports muscle recovery, training performance and steady weight gain when combined with a structured nutrition plan. SUPPORTS MUSCLE GROWTH & POST-WORKOUT RECOVERY – Each serving provides a balanced blend of protein and carbohydrates to replenish energy after training and support lean muscle growth. The combination of soy protein, whey isolate, casein and oat flour delivers both fast and sustained amino acid release, helping refuel muscles, restore glycogen levels and maintain a high daily protein intake.
