Dopamine's role extends beyond seeking pleasure to embracing the pleasure found in the pursuit itself. The combination of motivation, adrenaline, and noradrenaline enhances alertness and motivation, forming a trio that drives performance. Smelling salts may have a dopaminergic effect, contributing to this heightened state. For cognitive enhancement, 600 mg of alpha-GPC can increase alertness without necessarily needing extensive scientific validation. It’s regarded as a safer option compared to prescription stimulants. Additionally, theanine complements stimulants by reducing jitteriness, making it a common additive in energy drinks. Other notable substances include L-tyrosine, a dopamine precursor, and Modafinil, originally for narcolepsy but with proven cognitive benefits, especially for sleep-deprived individuals. These substances reflect a spectrum of options for enhancing focus and alertness, highlighting the importance of individual preferences and safety considerations.
