What Is It? 

  • EHP Labs RP Max is a stimulant based pre-work out designed with key ingredients to provide you with an optimal clean energy boost, improved cognitive function, enhanced muscular and cardiovascular endurance. Unlike many pre work out supplements, EHP Labs RP Max is not overloaded with unnecessary ingredients, and contains only the key attributes required to give you the best energy and focus required for a successful work out.   
  • EHP Labs PSI have yet again raised the bar for non-stimulant pre-workout supplements. PSI is a ‘Vasodilator Nutrient Delivery Maximiser’ matrix, in other words, a fast acting shirt tearing pump formula. Developed using clinically dosed ingredients resulting in a powerful pre-workout free from caffeine and other stimulants.
  • PSI boosts Nitric Oxide levels, which allows the body to expand the blood vessels, increase blood flow and transport nutrients and oxygen to stressed muscles while delaying the effects of fatigue. By utilising ingredients Citrulline Malate, L-AAKG and Agmatine Sulphate, PSI is able to increase circulation of blood and higher Nitric Oxide levels which makes you feel and look "pumped", this rapidly increases the body's ability to repair free radical damage as you work out. PSI have also included the addition of L-Tyrosine and Taurine allowing you to maximise your muscle contractions, create the mind-muscle connection and perform at a higher intensity.
