Watch the timing
Caffeine, Stimulants, and the Crash
Caffeine works, briefly. It also has a half-life long enough to affect sleep if taken after mid-afternoon, which then worsens tomorrow's energy. Our energy formula contains no caffeine or stimulant blend on purpose.
If you use coffee, keep it before 2pm and treat it as a tool rather than a baseline. Energy drinks with high sugar and caffeine give a sharp rise and a hard fall, which is the pattern most men are trying to escape.
