Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

  • 5-(N-methyl-2-amineopropyl)benzofurane[ACD/IUPAC Name]

An empathogen structurally similar to MDMA. Typically more visual than MDMA. Often reported to be much less stimulating and more relaxing than most other stimulating empathogens. Less psychedelic than 6-APB. Much longer lasting than MDMA.

Summary

These include such MDA-inspired substances as 5-APB, 6-APB and 5-EAPB, among others. 5-MAPB is the N-methylated form of 5-APB, analogously to how MDMA is the N-methylated form of MDA. This compound is known for its stimulating, euphoric and entactogenic effects that is capable of acting a quasi-substitute for MDMA proper, which has resulted in its rise in popularity as a research chemical that is easily accessible through the use of online vendors.

It has been sold as a designer drug since 2010. 5-MAPB is commonly found as the succinate and hydrochloride salt. The hydrochloride salt is 36% more potent by mass so doses should be adjusted accordingly.

Chemistry

5-MAPB

5-MAPB

It is comprised of an N-methylated ethylamine chain and a furan ring attached to a central benzene ring.

It can also be classified as a derivative of methamphetamine because the N-methylated ethylamine chain is alpha methylated in an analagous manner.

Molecules of the amphetamine class contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα.

The oxygen atom in the furan ring is placed at the 5 position, which generally constitutes more stimulating effects than when the oxygen is placed at the 6 position, which usually renders it more psychedelic in effect.

Interactions

Caution

  1. Mushrooms
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  2. LSD
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  3. DMT
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  4. Mescaline
    • The focus and anxiety caused by stimulants is magnified by psychedelics and results in an increased risk of thought loops
  5. 2C-x
    • The anxiogenic and focusing effects of stimulants increase the chance of unpleasant thought loops. The combination is generally uneccessary because of the stimulating effects of psychedelics. Combination of the stimulating effects may be uncomfortable.
  6. Cannabis
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  7. Ketamine
    • No unexpected interactions, though likely to increase blood pressure but not an issue with sensible doses. Moving around on high doses of this combination may be ill advised due to risk of physical injury.
  8. MXE
    • Risk of tachycardia, hypertension, and manic states
  9. Cocaine
    • This combination of stimulants will increase strain on the heart. It is not generally worth it as cocaine has a mild blocking effect on dopamine releasers like amphetamine
  10. Caffeine
    • This combination of stimulants is not generally necessary and may increase strain on the heart, as well as potentially causing anxiety and greater physical discomfort.
  11. Alcohol
    • Drinking on stimulants is risky because the sedative effects of the alcohol are reduced, and these are what the body uses to gauge drunkenness. This typically leads to excessive drinking with greatly reduced inhibitions, high risk of liver damage and increased dehydration. They will also allow you to drink past a point where you might normally pass out, increasing the risk. If you do decide to do this then you should set a limit of how much you will drink each hour and stick to it, bearing in mind that you will feel the alcohol and the stimulant less. Extended release formulations may severely impede sleep, further worsening the hangover.
  12. GHB/GBL
    • Stimulants increase respiration rate allowing a higher dose of sedatives. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
  13. Opioids
    • Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.

Dangerous

  1. DOx
    • The combined stimulating effects of the two can lead to an uncomfortable body-load, while the focusing effects of amphetamine can easily lead to thought loops. Coming down from amphetamines while the DOx is still active can be quite anxiogenic.
  2. NBOMes
    • Amphetamines and NBOMes both provide considerable stimulation. When combined they can result in tachycardia, hypertension, vasoconstriction and in extreme cases heart failure. The anxiogenic and focusing effects of stimulants are also not good in combination with psychedelics as they can lead to unpleasant thought loops. NBOMes are known to cause seizures and stimulants can increase this risk.
  3. 2C-T-x
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences. In extreme cases, they can result in severe vasoconstriction, tachycardia, hypertension, and in extreme cases heart failure.
  4. 5-MeO-xxT
    • The anxiogenic and focusing effects of stimulants increase the chance of unpleasant thought loops. The combination is generally unnecessary because of the stimulating effects of psychedelics.
  5. DXM
    • Both substances raise heart rate, in extreme cases, panic attacks caused by these drugs have led to more serious heart issues.
  6. PCP
    • This combination can easily lead to hypermanic states

Low Synergy

  1. Benzodiazepines
    • Both can dull each other's effects, so if one wears off before the other it's possible to overdose due to the lack of counteraction

No Synergy

  1. SSRIs

High Synergy

  1. N2O
  2. MDMA
    • Amphetamines increase the neurotoxic effects of MDMA

Psychological Effects

Pharmacological Effects

5-MAPB is a triple reuptake inhibitor for the monoamines norepinephrine, dopamine and serotonin as well as being an agonist for the 5-HT2A and 5-HT2B receptors. It has also been speculated that 5-MAPB acts as a releasing agent for the previously mentioned neurotransmitters. As a result, releasing agents such as 5-MAPB may exert their activity by effectively boosting the levels of the serotonin, norepinephrine and dopamine neurotransmitters in the brain by binding to and partially blocking the transporter proteins that normally clear and reuptake those monoamines from the synaptic cleft. This allows serotonin, dopamine and norepinephrine to accumulate within various reward and cognition-related areas in the brain, resulting in stimulating and euphoric effects.

Physical Effects

  • Stimulation - In terms of its effects on the user's physical energy levels, 5-MAPB is commonly regarded as significantly less stimulating and energizing than MDMA, while still retaining its core entactogenic effects. Unlike MDMA, which encourages activities such as running, climbing and dancing in a way that makes it a popular choice for musical events such as festivals and raves. The distinct style of stimulation which 5-MAPB presents can be described as mildly to moderately forced, trending more towards sedation and relaxation. This means that at higher doses, it becomes difficult or impossible to keep still as jaw clenching, involuntarily body shakes and vibrations become present, resulting in an extreme unsteadiness of the hands and a general lack of motor control, though to a far lesser degree than with MDMA.
  • Increased heart rate
  • Dehydration
  • Appetite suppression
  • Nausea
  • Temporary erectile dysfunction
  • Increased perspiration

Sensory Effects

  • Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.
