- Chocolate – 1.5x increase above baseline
- Sex (pursuit and act) – 2x baseline
- Nicotine (when smoked) – 2.5x baseline
- Cocaine – 2.5x baseline
- Amphetamine – 10x baseline
- Exercise – 2x baseline if you enjoy it, NO CHANGE if you don’t enjoy it
- Caffeine – does not increase dopamine significantly but it does increase dopamine receptors (yerba mate is the best source)
There are subjective experiences that differentially increase dopamine depending on enjoyment versus things like chocolate, sex, nicotine, etc., which universally increase dopamine.
Layering together multiple substances & activities that lead to big increases in dopamine can create pretty severe issues with motivation and energy right after those experiences
Telling yourself that exercise (fasting, etc) is good for your will reinforce the extent to which it is good for you at a chemical level.
