RAW CBUM Pump Pre-Workout is a stimulant-free pre-workout formulated specifically for athletes who want to support blood flow and muscular fullness without caffeine. Each serve contains 300mg of lion's mane mushroom extract and 1.5g of Nitrosigine — a patented inositol-stabilised arginine silicate studied for its ability to significantly elevate plasma arginine and nitric oxide levels. Zero caffeine. Available in Peach Mango and Sour Watermelon.

Nitrosigine is a research-backed ingredient with clinical studies demonstrating its efficacy for improving blood flow, cognitive performance and reducing muscle damage markers when taken consistently. At 1.5g per serve, the Pump Pre-Workout provides a meaningful dose. Lion's mane mushroom at 300mg supports cognitive clarity and focus through its neurotrophic properties — acting as a natural nootropic that enhances the mind-muscle connection during training without stimulants.

RAW CBUM Pump Pre-Workout is ideal for afternoon and evening training sessions, for those who are caffeine-sensitive, and as a stackable pump product alongside caffeinated pre-workouts for those who want both stimulant and nitric oxide support. Mix one serve in 300–400ml of cold water 20–30 minutes before training.
