It Helps You Quickly Gain Quailty Mass: BULKUP is a no-nonsense mass gain formula for those who want nothing but the quickest weight gain results with no compromise to quality. We have loaded each mega serving of this product with 770+ premium calories, 67g+ of fast and slow release protein and 117g of quality carbohydrates. 

It Is A Premium Formulation: BULKUP contains nothing but the best, highest-grade ingredients. While other budget weight gainer shakes are typically just loaded with cheap ingredients, we formulated BULKUP to be the polar opposite. At the core of this product is a complex of fast and slow release proteins (such as Whey Protein Isolate and Concentrate) that provide your body with gradual protein release throughout the day. We then added our expertly formulated Tri-Carb™ blend to introduce over 770 quality calories into the serving. Finally, we ensured the product contains 18 essential and non-essential amino acids to help support rapid lean muscle growth.

To boost your gains further, we recommend you stack this product with our Ovrdrive Appetite Enhancer.
