|Summary sheet: 2C-P|
|Routes of Administration|
2,5-Dimethoxy-4-propylphenethylamine (also known as 2C-P) is a lesser-known novel psychedelic of the phenethylamine class. 2C-P is a relatively obscure member of the 2C-x family of psychedelic phenethylamines and is one of the most potent, long-lasting, and dose-sensitive of the series.
2C-P was first synthesized and tested for human activity by Alexander Shulgin, who documented his findings in the 1991 book PiHKAL ("Phenethylamines I Have Known and Loved"). The reports found in the 2C-P PiHKAL entry remark on its depth and long onset and duration of action, with the commentary section describing 16 mg as a clear overdose with "physical consequences." The commentary also notes the small window separating an adequate dose from an excessive dose, suggesting it is relatively easy to overdose on.
User reports following the publication of PiHKAL tend to characterize the effects of 2C-P in terms of its unusually long duration, powerful, sometimes overwhelming visuals, and intense "body load" (such as persisting nausea, muscle tension and general bodily discomfort). 2C-P's head space and visuals have been described as possessing more similarities to alkylated 2C's like 2C-E than halogenated members like 2C-B or 2C-I. Some reports suggest it may be easier to experience agitation and delirium on 2C-P than other 2C's, perhaps owing to the ease in which it can be mishandled. As a result, it is considered to have a relatively questionable safety profile for a psychedelic.
Due its powerful effects and unusually long duration, 2C-P may be overly intense and difficult to use safely for those who are not already experienced with hallucinogens. It is strongly advised to use harm reduction practices if using this substance. Dosing practices like "eye-balling" (i.e. using the naked eye instead of a reliable milligram scale) or non-oral routes of administration should especially be avoided. Volumetric liquid dosing is commonly recommended when dealing with substances of this potency.

2C-P or 2,5-dimethoxy-4-propylphenethylamine is a substituted phenethylamine featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain. 2C-P contains methoxy functional groups CH3O- attached to carbons R2 and R5 and a propyl chain attached to carbon R4 of the phenyl ring. 2C-P belongs to the 2C family of phenethylamines which contain methoxy groups on the 2 and 5 positions of the benzene ring.
2C-P's psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist. However, the role of these interactions and how it results in the psychedelic experience continues to remain elusive.
The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. These effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.
- Stimulation - 2C-P is considered to be very energetic and stimulating in a fashion that is comparable to that of 2C-B, 2C-I and other substances within the 2C-x family, being encouraged instead of forced.
- Spontaneous bodily sensations - In comparison to 2C-E or 2C-B, the "body high" of 2C-P can be considered as mild although still capable of becoming very powerful and highly physically euphoric. It is similar yet distinct from the "body high" experienced on 2C-E, 2C-B, and LSD. The sensation itself can be described as intense and will manifest itself in the form of a continuously shifting tingling sensation that travels up and down the body in spontaneous waves. This is coupled by an equally intense yet slightly uncomfortable energetic pins and needles sensation that constantly encompasses a person’s entire body as well as a slight warm glow that manifests itself much less consistently than the other two physical components. All of these are capable of becoming very physically euphoric.
- Tactile enhancement - This effect is particularly prominent but capable of going in both pleasurable and uncomfortable directions. This can result in pleasurable tactile sensations but also enhances bodily aches and pains which one may not have previously been aware of to the point of extreme discomfort.
- Bodily control enhancement
- Temperature regulation suppression - 2C-P is reported to be able to cause large perceived increases and decreases in temperature in a dose dependent manner. This can become extremely uncomfortable if not dangerous at larger doses due to the fever-like delirium that is sometimes reported.
- Increased heart rate
- Increased blood pressure
- Nausea - Mild to extreme nausea is consistently reported when consumed in moderate to high dosages and either passes once the user has vomited or gradually fades by itself as the peak sets in.
- Increased libido - A common theme found in many 2C-P reports is the way in which it can heighten and enhance sexual arousal. When experienced, this sensation is not overwhelming or out of control but simply remains something that the user is constantly aware of. If sexual activities of any kind are engaged in, they are have been reported to be immensely more pleasurable than anything that can be achieved in a sober state.
- Pupil dilation
- Teeth grinding - A very common effect of 2C-P, and more pronounced with 2C-P than other 2C's or psychedelic substances in general. Can become very uncomfortable, especially with higher doses.
- Drifting (melting, flowing, breathing and morphing) - In comparison to other psychedelics, this effect can be described as highly detailed, slow and smooth in motion, static in appearance and unrealistic/cartoon-like in style.
- After images
- Symmetrical texture repetition
- Color shifting
- Scenery slicing
- Depth perception distortions
The visual geometry present can be described as being more similar in appearance to that of 4-AcO-DMT or ayahuasca than that of LSD, 2C-B or 2C-I. They can be comprehensively described as structured in their organization, organic in geometric style, intricate in complexity, large in size, fast and smooth in motion, colorful in scheme, glossy in color, sharp in their edges and equally rounded and angular in their corners. It gives off a contradictory natural and synthetic feel that at higher dosages are significantly more likely to result in states of Level 8B visual geometry over Level 8A. There seems to be visual geometry that is distinct from 2C-E, psilocin and ayahuasca and can be described as faster moving and more intense in proportion to cognitive and physical effects than 2C-E.
2C-P produces a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of many other commonly used psychedelics. This holds particularly true in comparison to other 2C-x phenethylamines such as 2C-B or 2C-I. These effects include:
- Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - In comparison to other psychedelics such as LSD, 2C-P is extremely high in hallucinations embedded within visual geometry. This particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact. They are more common within dark environments and can be described as lucid in believability, interactive in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental nature in their overall theme.
- Unspeakable horrors - This is an effect that is typically associated with deliriants rather than psychedelics. Based on anecdotal reports, they only tend to occur at higher doses and are likely a result of the pronounced temperature increasing properties this substance has compared to other 2C-x and psychedelics, which can lend readily to delirium-like states.
The cognitive effects of 2C-P have been described as both insightful and relatively normal in their thought processes up to moderate dosages, after which their confusing, and disorienting effects can increase considerably.

Toxicity and harm potential
This toxicity and harm potential section is a stub.
As such, it may contain incomplete or even dangerously wrong information. You can help by expanding or correcting it.
The toxicity and long-term health effects of recreational 2C-P use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 2C-P is a research chemical with very little history of human usage.
Anecdotal reports suggests that there are no negative health effects attributed to simply trying the substance by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
It is strongly recommended that one use harm reduction practices when using this substance.
The LD50 of 2C-P has not been established. However, it is believed that 2C-P is likely to have a smaller therapeutic window compared to other 2C's, meaning a lethal dose may be achieved more easily. 2C-P is known to be highly dose-sensitive: a difference of 2 or 5 milligrams may radically change the nature of the experience along with its safety profile. Users who wish to take high doses of this compound are advised to titrate upward slowly, use reliable milligram scales to measure doses, and avoid non-oral routes of administration such as insufflation or injection.
In 2017, a 25-year old British female died following the ingestion of a large dose of 2C-P at a music festival. No source reported clear evidence that 2C-P by itself led to the immediate death of the female.
Dependence and abuse potential
As a serotonergic psychedelic, 2C-P is considered to have a low potential for abuse and dependence.
Tolerance to the effects of 2C-P are built almost immediately after ingestion. After that, it takes about 3 days for the tolerance to be reduced to half and 7 days to be back at baseline (in the absence of further consumption). 2C-P produces cross-tolerance with all psychedelics, meaning that after the consumption of 2C-P all psychedelics will have a reduced effect.
Although many psychoactive substances are reasonably safe to use on their own, they can quickly become dangerous or even life-threatening when taken with other substances. The following lists some known dangerous combinations, but cannot be guaranteed to include all of them. Independent research should always be conducted to ensure that a combination of two or more substances is safe to consume. Some interactions listed have been sourced from TripSit.
- Cannabis - Cannabis has an unexpectedly strong and somewhat unpredictable synergy with the effects of psychedelics. Extreme caution is advised when using this combination as it can significantly increase the chances of a negative psychological reaction like anxiety, paranoia, panic attacks, and psychosis. Users are advised to start off with only a fraction of their normal cannabis dose and take long breaks between hits to avoid over intake.
- Stimulants - Stimulants affect many parts of the brain. Combined with psychedelics, stimulation can turn into uncontrollable anxiety, panic, thought loops, and paranoia. This interaction may result in an elevated risk of mania and psychosis.
- Lithium - Lithium is often prescribed as a treatment for bipolar disorder. It may possibly cause elevated risk of seizures and psychosis due to its glutaminergic and GABAergic effects.
- Tramadol - Tramadol lowers the seizure threshold and psychedelics may act as triggers for seizures in susceptible individuals.
2C-P is not scheduled under the UN Convention on Psychotropic Substances. It is considered to exist in a legal grey area in many countries, meaning that while it is not specifically illegal, individuals may still be charged for its possession under certain circumstances such as under analogue laws and with the intent to sell or consume.
- Austria: 2C-P is illegal to possess, produce and sell under the NPSG (Neue-Psychoaktive-Substanzen-Gesetz Österreich).
- Canada: 2C-P would be considered Schedule III as it is a derivative of 2,5-dimethoxyphenethylamine.
- China: As of October 2015, 2C-P is a controlled substance in China.
- Denmark: 2C-P is on the list of Schedule B controlled substances.
- Germany: On December 13, 2014 2C-P was added to the controlled substance act ("BtMG"), making it illegal to produce, sell or possess.
- Latvia: 2C-P is a Schedule I controlled substance.
- Switzerland: Possession, production and sale is illegal.
- United Kingdom: 2C-P is a Class A drug in the United Kingdom as a result of the phenethylamine catch-all clause.
- United States: 2C-P is a Schedule I controlled substance. This means 2C-P is illegal to manufacture, buy, possess, process, or distribute without a license from the Drug Enforcement Administration (DEA).
