PUMP AND FOCUS
WITHOUT CAFFEINE.
SWELL is a caffeine-free pre-workout designed to deliver powerful pumps, hydration, and mental clarity without a stimulant load. While stimulant-free, SWELL mirrors key elements of SHOCK’s performance-support infrastructure, making it a serious option for athletes seeking high-quality training without caffeine.
Built around HydroMax® glycerol, SWELL supports hydration, cellular volumization, and muscle fullness during training. It also includes the same focus-support ingredients found in SHOCK—huperzia serrata extract, pine bark extract, lion’s mane mushroom, and alpha-GPC—helping maintain mental engagement and training intent throughout each session.
Ideal for late-night gym sessions, stimulant-sensitive athletes, or those stacking with stimulant-based products, SWELL delivers controlled performance support without compromising focus or pumps.
What It Delivers
- Deep muscle pumps powered by a glycerol-based pump complex
- Improved hydration and endurance during training
- Clear, focused mental performance without stimulants
- Ideal for evening workouts and stimulant-free training
