How to take 2-FDCK

Administration

You can either take the substance intramuscularly, intravenously, orally, smoke it, or snort it.

Snorting the drug is likely to give you more energy and a clearer headspace.

Those who snort 2-FDCK tend to enjoy the experience more and find the drug more euphoric.

If you decide to inject the substance, make sure your needle is clean and nobody has used it before you, otherwise you’ll be at risk of getting infected. One additional downside of injecting the drug is that you may experience muscle pain.

The drug can also be swallowed. When taken orally, 2-FDCK is more dissociative and less stimulating than with other routes.

Interestingly, the higher the dose you take, the less it matters which route of administration you chose as far as the effects of the drug.

Dosage

15 mg = Threshold
10-25 mg = Light dose
25-70 mg = Regular dose
70-140 mg = Strong dose
140+ mg = High dose

Doses higher than 140 mg are not recommended since they can easily lead to mania and psychosis. Never take such a high dose if you value your mental health.

Never start with a strong dose. You may be more sensitive to the substance than others and it might cause you irreversible damage if you don’t take it responsibly.

Those who need less of the substance to reach desired effects include older and extremely lean people.

Since tolerance to 2-FDCK is developed quickly, you want to wait for at least 1-2 weeks between dosing. Otherwise, you would need a higher dose to reach the desired outcome.

Safety checklist

Maximize the benefits

Keep in mind that integration is even more important than the trip itself. Taking the drug would be almost useless if you didn’t retain any lessons in your day-to-day life.

What will help you the most is contemplating about the experience – be it by journaling, thinking about the trip, or sharing your memories with a trusted friend.

Distracting thoughts can get in the way, which is why you want to spend the day after your trip without TV, social media, and other distractions.

If you can, spend time in silence and solitude. Meditate, go for a walk, contemplate the experience.

Duration

What does 2-FDCK feel like?

The effects of 2-FDCK are somewhere between those of ketamine and PCP, although the drug is more similar to ketamine than to PCP.

The main difference between 2-FDCK and ketamine is that 2-FDCK is usually more pleasant and slightly stimulating. 2-FDCK trips also last longer than those of ketamine.

2-FDCK is also similar to DCK but there are a few differences.

DCK is usually more euphoric while 2-FDCK is more predictable and lighter. 2-FDCK lies somewhere between DCK and ketamine, it is therefore more similar to ketamine.

Unfortunately, higher doses can cause psychosis and manic episodes and the chance is higher than with ketamine or most other drugs. These can last for a long time after you get off the substance.

As a dissociative, 2-FDCK can detach you from your body, senses, and the environment. You may feel like you’re controlling your body from a distance (similarly to playing a 3rd person video game).

At high doses, you may also enter the K-hole. When that happens, you will not be conscious of your body so never take a high dose in an unsafe environment!

Reaching the K-Hole, however, is harder than with ketamine because 2-FDCK is not as dissociative.

Other common short-term effects include:

Euphoria
Increased creativity and open-mindedness
Mindfulness, being present
Introspection
Higher capability for love and compassion
Pain relief
Memory suppression
Anesthetic effects
Numbness
Visual effects (typically weak and unpredictable)
Distortions of size, shape, and distance
Manis
Psychosis
Confusion
Inability to talk
Increased body pressure
Worse thermoregulation
Difficulty urinating
Anxiety, paranoia
Vulnerability

The higher dose you take, the more intense these effects will be. This especially applies to the dissociative effects.

Your past experiences with drugs also play a big role in the effects of 2-FDCK.

With all this said, it is impossible to accurately describe the experience through human language.

Bad trips can happen but you can partially prevent them by following the tips below.

After-effects

2-FDCK rarely causes a withdrawal. If you take the drug on a regular basis, some withdrawal symptoms may occur but they will be mild.

You may experience insomnia and find it hard to fall asleep the day after taking the drug.

Cognitive impairment, numbness, and impaired vision can also stick for over a day after taking the drug. Do not drive if you don’t feel 100% sober!

Many users get a pleasant afterglow when the drug wears off. They feel better and their depression can disappear for a few days, sometimes even weeks. At the same time, some users actually feel depressed after taking 2-FDCK.

Bad trips

Bad trips mostly happen because people take the substance irresponsibly. If you take this drug the right way, there is a much lower chance you’ll get a bad trip but it still can happen.

In case you take 2-FDCK responsibly and you still get a bad trip, there is a positive side to that.

During a “bad” trip, negative emotions are coming up from your subconscious mind. They have always been there whether you are aware of it or not. They have been damaging your life and a difficult trip is an opportunity to process these traumas and unpleasant feelings and let go of them.

So instead of calling bad trips bad, call them challenging.

Why they happen

The most common reasons for getting a bad trip are:

Tripping in an unsafe environment (in public, at a party, even nature doesn’t feel safe if you take higher doses)
Facing difficult times in your day-to-day life (a break-up, death of a loved one, …)
Rejecting to let go and trying to hold on to your ego and control the state
Being afraid of the trip (either because of the stigma around psychedelics or because you are not sure how pure your substance is)
Mixing the psychedelic with alcohol, weed, or other drugs
Expecting a bad trip (it can easily become a self-fulfilling prophecy)
Taking a high dose

How to cope with a bad trip

Do not perceive this experience as something bad, remember that facing these difficult emotions can be extremely healing
Fully surrender to the experience, do not try to feel good
If you’re alone, call a trusted friend to come over and keep you safe

How to end a bad trip

In case you are not ready to face your inner demons yet, there are a few ways to end a bad trip.

One possible way is to put on music that is familiar to you. Another way is to switch up your location and move from one place to another. This can completely change your train of thought.

Interactions

Qualia Mind
This nootropic is comprised of 28 ingredients designed to support and maximize your brain function. These ingredients act synergistically and many of them will protect you from the neurotoxic effects of psychedelics. Qualia will also make your trips more pleasant and help you retain more benefits from them.
Herbs
Herbs can help calm you down. Herbal teas (chamomile, lemon balm, valerian root, …) are especially helpful.
Green tea
Tea makes you both more alert and calm at the same time. It also contains neuroprotective antioxidants, such as EGCG.
CBD
CBD has a calming effect.
Weed
Marijuana will greatly intensify the trip.
Nitrous oxide
Nitrous oxide will multiply the intensity of your trip.
Benzodiazepines (Valium, Xanax, …)
The combination may lead to a loss of consciousness and vomiting. Vomit aspiration is the most dangerous risk.
Alcohol, GHB, GBL, Opioids
Just like benzodiazepines, these drugs can cause vomit aspiration if you combine them with dissociatives. 2-FDCK can also reduce opioid tolerance, increasing the risk of overdose.
SSRIs or MAOIs
Not only will these antidepressants greatly decrease the intensity of your trip, but they can also lead to long-lasting side effects. You may also go unconscious and die from vomit aspiration.
Stimulants
The combination can lead to heart problems or hyper mania.
Tramadol
Combining the two can cause seizures.

Legality

As of 2021, 2-FDCK is illegal in most countries of the world.

In some European (and a few other) countries, you can legally buy the substance from the internet for “chemical research” purposes. You cannot consume the substance legally but whether or not anyone cares is a different story.

In many countries, you can own a small amount of the substance for personal use without getting in legal trouble.

FAQ

Yes. Tolerance develops quickly and can last for months or even years.

However, it usually takes 3-7 days to cut the tolerance in half and by 2 weeks, most users will be as sensitive to 2-FDCK as if they never took it before.

2-FDCK also has cross-tolerance with other dissociatives, like ketamine and DXM.

2-FDCK acts primarily as an NMDA receptor antagonist, meaning it binds to and blocks the activity of the NMDA receptor, the receptor responsible for the transmission of neural impulses in the central nervous system.

Always take the substance in a safe place and keep a trusted friend nearby to take care of you in case something goes wrong.

If you are a mentally stable individual who does not suffer from psychosis or have a predisposition to bipolar or schizophrenia, there is virtually no way you would develop any mental illnesses because of taking the drug. With that said, high doses of 2-FDCK can lead to mania and drug-induced psychosis. The drug isn’t nearly as psychologically safe as ketamine or some other dissociatives.

The drug stays in your blood for around 24 hours, in your saliva for up to 2 days, in your urine for 14-30 days and in your hair, the substance can be detected for a few months.

Keep your powder or liquid in a cold dark place, preferably with no air.

If you don’t do this, the drug will lose potency over time.

It is recommended to stop eating 2-3 hours before taking the substance, especially if you take it orally.

Alcoholics
Those who don’t want to put their mental health at risk
Brain cancer patients
Those who have uncontrolled hypertension (high blood pressure)
People with a history of heart attacks
People with thyroid disease (hyperthyroidism and hypothyroidism)
Immature psychonauts who are not willing to follow the safety guidelines
People who suffer from psychosis
People who have a familial history of schizophrenia
Those who suffer from HPPD
People who are are predisposed to bipolar disorder or are going through a manic phase
Those who tried other dissociatives and noticed unpredictable side effects

Compared to ketamine, 2-FDCK is more addictive because of its stimulant and euphoric effects. This is especially the case for users who take the substance with the purpose of having fun.
