Gene Blast Stim-Free Pump is developed for athletes who prioritise muscular drive and session quality without relying on caffeine or central nervous system stimulants. It is built for structured training environments where consistency and repeatable output matter.
Rather than relying on citrulline malate blends, this formula centres on pure L-Citrulline with clearly defined dosing. Many malate products include added malic acid, whereas this approach focuses on precise ingredient delivery within performance-based programming.
Plant-derived nitrate sources, glycerol-based hydration compounds and complementary amino acids are included to align with resistance training, bodybuilding routines and high-volume gym sessions where muscular fullness is prioritised.
Because the formula contains no caffeine, it can be used during evening workouts, lower-stim training blocks or alongside other supplements where total stimulant intake is managed strategically.
Electrolytes are incorporated to support fluid equilibrium during demanding sessions, particularly in extended workouts or warmer conditions.
The powder disperses easily in chilled water and can be adjusted based on session demands. It may also be integrated into broader supplement plans alongside protein powders or creatine monohydrate.
Manufactured in GMP-compliant facilities with fully disclosed ingredient amounts, this product reflects Gene Blast’s formulation-first philosophy — transparent, performance-led and built for serious training environments.
