Stim Reaper contains four stimulants that increase energy and improve concentration and can also assist fat loss. Power through your workouts no matter how tired you are or if food is low on a diet! With a high caffeine content of 400mg per scoop, we'd not recommend using this after mid-afternoon as it may interrupt sleep. Save for your most challenging sessions such as a big leg day!
