Creatine's effect on strength is driven by increasing the body's stores of phosphocreatine , which is used during high-intensity exercise to produce ATP-the primary energy currency of the cell [R]. In addition, you can expect a gradual increase in muscle size and body weight over time through the process of osmosis , which draws water into muscle tissue [R]. As one of the most studied and effective performance-enhancing supplements available, it's important to take creatine daily at a full saturation dose to ensure your muscles remain fully loaded and ready to perform. Creatine is a fantastic ingredient in both pre-workout and post-workout contexts for improving strength, power output, and muscle size-and may even support cognitive performance [R, R, R, R, R]. However, we already include the full saturation dosage of creatine in our pre-workout and post-workout products. That's why we created a standalone creatine product , allowing you to take your daily creatine dose on days when you're not using a pre-workout or post-workout formula.
