Research into various amino acids, stimulants and other ergogenic ingredients has shown that many can have positive acute effects on athletic performance when taken prior to training. Pre-workout formulas typically contain ingredients such as creatine, arginine, beta alanine and caffeine as all of these are well researched into their abilities to enhance performance by either increasing strength, endurance or mental focus and energy. The dosages of these ingredients can vary greatly depending on the main focus of the formula as some are designed primarily to enhance strength whilst others are designed to focus more heavily on stimulating the central nervous system.
After cutting out all the junk and getting rid of products that might make users a little too jittery, we were finally able to arrive at our top picks.
