Use Jym Supplement Science PreJYM Pre-Workout for clean pumps, endless energy and ultimate workout results! Like every other supplement from Jym, this pre-workout is built on sound knowledge, solid science and quality manufacturing to ensure the best standard. This formula has been designed to increase strength, boost energy and maximise cognitive performance with hand-picked stimulants, synergistic nootropics and clinically researched amino acids for improved lactic acid removal, muscle recovery and enhanced output. If you’d consider yourself a gym enthusiast, athlete or bodybuilder, then this powerful pre-workout is an essential supplement you should have in their arsenal.

Each scoop of Jym Supplement Science PreJYM Pre-Workout contains the core ingredients BCAA’S, creatine, citrulline malate, beta-alanine, betaine, alpha GPC, caffeine and huperzine. BCAA’s are branched-chain amino acids, which are the building blocks of protein – muscles cannot grow without them. They help create protein and stop the body from going through its protein stocks as quickly plus they improve mental focus during exercise so that you can fully concentrate on each step in your workout. Beta-alanine is an amino acid your body needs to produce carnosine, which helps improve exercise performance. Caffeine in PreJYM Pre-Workout is a well-proven stimulant that has shown to improve tolerance for pain caused by exercise, increase alertness, sharpen focus, help burn fat, improve mood, and help active people push through tough sessions. Along with other powerful ingredients, this formulation boosts ultimate recovery, focus and energy. Are you ready for the best workout you’ve ever had?


  • Mix 1 scoop with 360ml - 385ml of chilled water or favourite beverage and consume prior to exercise
  • Use a half serving initially to assess tolerance
