Overview

RAW Nutrition CBUM Thavage V4 is the fourth iteration of Chris Bumstead's signature pre-workout, now providing 40 servings (up from 20-30 in previous versions). The formula delivers 9g L-citrulline, 3.2g beta-alanine, 3.5g betaine, 2g taurine, 300mg caffeine, 200mg Alpha-GPC, and 50mg Astragin for enhanced absorption. The V4 update increased the serving count while maintaining clinical doses across the board. The 9g citrulline dose is among the highest in any pre-workout — research shows 6-8g is the clinical range, so 9g provides a generous surplus. Chris Bumstead (5x Classic Physique Mr. Olympia) personally uses this formula in his training.
