Caffeine was earlier prohibited but now in the monitoring program. As of 2016, the list contains
"Bupropion, caffeine, nicotine, phenylephrine, phenylpropanolamine, pipradol and synephrine: These substances are included in the 2016 Monitoring Program, and are not considered Prohibited Substances."
What does it mean to be under monitoring? Can I drink coffee before competitions under WADA's supervision or use synephere stimulants?
