Here is a first hand account from someone who took 2C-P. Remember to always research and gather as much information as possible before trying any drug.
Oral dose: 20mg

Intense come-up during onset. Anxiety and excitement. Takes between 30-90 minutes to get over the "hump" then felt relaxed.
Open eyed visuals much like LSD, but a more intense come up
