C4 Smart Energy

Surprisingly smart for a pre-workout brand. Cognizin citicoline at 250mg plus tyrosine is a legit cognitive stack on top of 200mg natural caffeine. Missing L-theanine to smooth the caffeine edge, but the nootropic additions actually earn their spots.

7.5/10
VERY GOOD

Caffeine at 200mg is optimal dose. Cognizin Citicoline at 250mg is a solid nootropic dose (clinical studies use 250-500mg). N-Acetyl Tyrosine at 200mg hits 57% of optimal. For an energy + focus product, the core delivers well. B vitamins are just support. Clean formula for what it claims to do.
