According to Muscle and Fitness.
"Chocamine is a cocoa extract that has a number of active ingredients -- such as caffeine, tyramine, theobromine and phenylethylamine (PEA) -- that boost energy, mood, concentration, alertness and metabolism, and suppress appetite. Caffeine prevents mental and physical fatigue by blocking receptors that notify the brain of low energy levels. Tyramine is a biogenic amine that can cause the release of the neurotransmitter. Theobromine is similar to caffeine but has a longer half-life, meaning it stays active in the body for a longer time. PEA is a naturally occurring compound that behaves as a stimulant in the brain, with effects similar to those of amphetamine."
