EHPLabs - PSI Vasodilator Nutrient


Availability: Out of stock



PSI Vasodilator Nutrient Delivery Maximizer is an effective scientifically dosed non-stimulant (caffeine-free) pre-workout by EHPlabs. PSI is meticulously engineered to boost physical performance during exercise by enhancing natural energy production and vasodilation. The unique combination of powerful nitric oxide and muscle cell plasma volumizing ingredients in PSI pre-workout maximises nutrient and oxygen delivery to working muscles, assisting you to force out extra reps, as well as giving you a mind-blowing pump.

PSI Vasodilator Nutrient Delivery Maximizer sets a new standard for non-stim pre-workout products. PSI Pre-workout promotes mental focus, clarity and serotonin release factors by combining the optimal ratio of taurine and tyrosine. PSI Non-Stim pre-workout will assist you with your conscious muscle contractions during physical exercise (“mind-muscle connection”), as tyrosine is a precursor to neurotransmitters,thyroxine and growth hormone.


  • - Cell volumization
  • - Muscle hydration
  • - Nutrient and oxygen delivery system
  • - Metabolism and mood enhancers
  • - Increased pump, strength and endurance
  • - Works synergistically


Attention:  PSI does NOT contain any caffeine or other central nervous stimulants.  You may consume PSI in the evenings prior to training and it should not affect your ability to sleep.  PSI will increase oxygen and nutrient delivery to working muscles which may cause a natural increase in energy (ATP production).
