BULKUP Gainer works in 2 key ways to trigger rapid weight gain:


It's extremely high in calories per serving:

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, over 18 essential amino acids, and finally 117g of quality carbohydrates.


It uses the highest-grade fast and slow release proteins:

BULKUP contains nothing but the best ingredients money can buy. While other budget weight gainer shakes are typically just loaded with cheap carbs and sugar, 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.

How To Use BULKUP Gainer:

1. Mix a 100-200g serving with approximately 500ml water or milk.
