New & Improved Formula
AFTERSHOCK™ Critical Mass is a lean mass gainer formulated with high-quality nutrients to support muscle growth and recovery.* Each serving delivers 60 g of protein from a dual-source blend of whey protein isolate and milk protein isolate. This ultra-low-lactose, low-glycemic formula is designed to be easy on digestion and minimize bloating.*
Support Lean Mass Without the Bloat
Unlike typical mass gainers that are loaded with high-glycemic carbs, Critical Mass focuses on providing nutrient-dense calories to support quality muscle development.* This makes it a suitable option for those aiming to build lean mass while avoiding unwanted fat gain.*
Directions: Mix 1 serving (170 g / 3 scoops) with 12 to 16 oz of water and consume up to several times daily.** For additional calories, blend with ingredients such as fresh fruit, peanut butter, whole milk, or cooked oatmeal.**
