Edge Pump is a high-performance, stimulant-free pre-workout formula created for athletes and lifters who want to experience massive muscle pumps, enhanced vascularity, and better blood flow — without the use of caffeine or other stimulants. It’s perfect for evening workouts, stack combinations, or users who are sensitive to stimulants but still want elite-level performance and muscle fullness.

This formula combines proven nitric oxide boosters and hydration agents like L-Citrulline, GlycerSize™, VasoDrive-AP®, Agmatine Sulfate, and S7™, delivering a multi-pathway pump that lasts throughout your workout.

Who is it for?

Edge Pump is ideal for:

  • Individuals who want massive pumps and vascularity without stimulants

  • Athletes who train in the evening or cycle off caffeine

  • Users stacking with stimulant-based pre-workouts and wanting a pump/NO boost

  • Physique athletes preparing for shows or photoshoots

  • Anyone looking to maximise muscle fullness and blood flow during hypertrophy training

Suitable for both men and women. Safe for daily use and stimulant-free.

Our Impression

Edge Pump delivers noticeably complete, dense muscle pumps and a consistent vascular effect without the need for any stimulants. During testing, users reported enhanced endurance, hydration, and a “skin-splitting” muscle feel, especially during high-volume workouts. The formula is clean, transparent, and built for performance — ideal for those who want total control over their stimulant intake while still getting elite results in the gym.

Whether stacked or taken alone, it delivers on its promise: pump, power, and performance — without compromise.

Ingredient Breakdown (Per Full Serving – 1 Scoop)




  • L-Citrulline (6000 mg)One of the most effective nitric oxide precursors. Increases vasodilation, blood flow, oxygen delivery, and muscle pump. Also supports endurance and reduces fatigue during high-rep sets.


  • Betaine Anhydrous (2500 mg)Enhances power output, cellular hydration, and muscular endurance. It may also support body composition and recovery.


  • GlycerSize™ (Glycerol Powder – 2000 mg)A concentrated form of glycerol that draws water into muscle cells for a hyperhydration effect. Improves fullness, vascularity, and performance.


  • Agmatine Sulfate (1000 mg)Modulates nitric oxide synthase activity and enhances blood flow. Also supports focus and may reduce pain perception during intense training.


  • VasoDrive-AP® (508 mg)A patented compound derived from casein peptides that promotes vasodilation by inhibiting angiotensin-converting enzymes (ACE). Enhances pump, nutrient delivery, and blood pressure regulation.


  • S7™ (50 mg)A blend of seven plant-based ingredients (including green tea, blueberry, and turmeric) clinically shown to increase nitric oxide production by up to 230% at a low dose. Works synergistically with citrulline and agmatine.
