With TruLabs Pre-Workout, you have two options to choose from. Option 1 allows you to follow our designed system and cycle between the three different formulas on a monthly basis. Option 2 gives you the flexibility to find the formula that works best for your body and stick with it, or you can alternate between two formulas instead of all three. Our system is designed to accommodate personal preferences, allowing you to personalize your experience based on what works best for you.
