Caffeine is the engine of any pre-workout. It boosts focus and energy. C4 Sport offers options with 135mg or 200mg per serving, so you choose your intensity.
If you are sensitive to stimulants, start with the lower dose. For experienced athletes, the higher dose may give you that extra edge. Always check your tolerance before increasing.
Muscular Endurance
Beta-alanine is a key ingredient in C4 Sport. It helps delay fatigue so you can push through more reps. CarnoSyn Beta-Alanine is a clinically studied form that supports endurance.
You might notice a harmless tingling sensation. That is normal and shows the ingredient is working. For aging athletes, endurance becomes even more critical. See our sports nutrition supplements for healthy aging guide for more tips.
