MDMA Dosage Guide

Evidence-based dosing, safety thresholds, and harm reduction for Molly, Ecstasy, and pure MDMA.

⚠️ Critical Safety Warning

MDMA can cause life-threatening hyperthermia, hyponatremia (water intoxication), and serotonin syndrome. Never mix with MAOIs, SSRIs, DXM, or tramadol. Test your substances with a reagent kit. This guide is for educational harm reduction only.

MDMA Dosage Calculator

The standard harm-reduction formula is 1.5mg per kg of body weight (or 0.68mg per lb) for a full dose, with a maximum recommended single dose of 120mg for neuroprotection.





Recommended Starting Dose
0mg
Common Dose

MDMA Dosage by Weight

Weight Light (mg) Common (mg) Strong (mg) Max Safe (mg)
50kg / 110lbs 40-50mg 60-75mg 80-100mg 100mg
60kg / 132lbs 50-60mg 75-90mg 100-120mg 120mg
70kg / 154lbs 60-70mg 90-105mg 120-140mg 120mg*
80kg / 176lbs 70-80mg 105-120mg 140-160mg 120mg*
90kg / 198lbs 80-90mg 120-135mg 160-180mg 120mg*
100kg / 220lbs 90-100mg 135-150mg 180-200mg 120mg*

*Regardless of body weight, doses above 120mg significantly increase neurotoxicity risk. Heavier users should not exceed 120mg to protect serotonin axons.

Redosing: The “Booster” Rule

🚫 Never redose more than once per session.

If you choose to extend your roll, take 50% of your initial dose 90-120 minutes after the first dose. Example: If you took 100mg initially, take 50mg at the T+90 mark. Do not redose after T+2 hours—it only increases side effects without adding euphoria.

Pre & Post-Load Supplements

These supplements are backed by research to reduce neurotoxicity and improve recovery:

🛡️ Pre-Load (2-6 hours before)

  • Vitamin C: 1000-2000mg (antioxidant)
  • ALCAR: 500mg (neuroprotective)
  • Magnesium Glycinate: 200mg (reduces jaw clenching)
  • Green Tea Extract: EGCG (inhibits MDMA metabolism to toxic MDA)

⚡ During (Take at T+0)

  • Magnesium: 200mg more if jaw tension persists
  • Gum: Sugar-free to protect teeth from grinding
  • Electrolytes: Not plain water—max 500ml/hour

🌙 Post-Load (Before bed + next day)

  • 5-HTP: 100mg (only after 24+ hours)
  • Vitamin C: 1000mg
  • Alpha-Lipoic Acid: 300mg
  • Melatonin: 3-5mg (sleep aid)
  • EGCG: 400mg (prevents heart valve damage)

Harm Reduction Checklist

  • Test your stuff: Use Marquis, Mecke, and Simons reagents. Fentanyl test strips are mandatory in 2025.
  • Wait 3 months: The “3-month rule” exists for a reason. Frequent use causes permanent serotonin depletion and cognitive deficits.
  • Stay cool: Hyperthermia is the #1 killer. Take breaks from dancing, use fans, and avoid overheated venues.
  • Don’t chug water: MDMA causes water retention. Drink 250-500ml per hour max. Add electrolytes.
  • No SSRIs: Taking MDMA on SSRIs is dangerous (serotonin syndrome) and wastes the drug (blunted effects).
  • Have a sitter: Especially for first times. Someone sober should know what you’ve taken.

Know the Signs of Overdose

Extreme confusion, seizures, vomiting, body temperature above 40°C (104°F), irregular heartbeat, or loss of consciousness. Call 911 immediately. You will not be arrested for seeking medical help.

How Long Does MDMA Last?

Phase Timeline Effects

Ketamine Dosage Guide

Medical, therapeutic, and recreational dosing for nasal, oral, and intramuscular routes. Includes K-hole thresholds and bladder safety.

⚠️ Critical Safety Warning

Ketamine is a dissociative anesthetic. High doses cause loss of motor control and consciousness. Never use alone. Chronic use causes permanent bladder damage (ketamine-induced cystitis) and cognitive impairment. In Canada, ketamine is a Schedule I controlled substance. Medical use is restricted to anesthesia and emerging psychedelic therapy clinics.

Ketamine Dosage by Route of Administration

Bioavailability varies dramatically by route. Intranasal (snorting) is ~45% bioavailable. Oral is ~20%. Intramuscular (IM) is ~93% and should only be performed by medical professionals.

~45% Bioavailable

Intranasal (Snorting)

The most common recreational and therapeutic route. Onset is 5-15 minutes. Duration 45-90 minutes.

Low / Social: 15-30mg
Mild relaxation, light dissociation, social lubrication. Similar to 2-3 drinks.
Common: 30-60mg
Clear dissociation, time distortion, music enhancement, mild visual distortions.
Strong: 60-100mg
Heavy dissociation, significant visual changes, difficulty walking (K-legs).
K-Hole: 100-150mg+
Complete dissociation from body. Out-of-body experiences. Not for public spaces.
~20% Bioavailable

Oral (Capsules / Liquid)

Smoother onset but less predictable. Onset 15-30 minutes. Duration 1-2 hours. Easier on the nose and bladder than frequent nasal use.

Low: 50-100mg
Subtle relaxation, anti-depressive effects, mild perceptual changes.
Common: 100-200mg
Full dissociative state, therapeutic introspection, time dilation.
Strong: 200-300mg
Heavy dissociation approaching K-hole territory. Nausea risk increases.
K-Hole: 300-500mg+
Complete ego dissolution. Only for experienced users in controlled settings.
~93% Bioavailable

Intramuscular (IM)

Medical/clinical only. Used in psychedelic therapy clinics and anesthesia. Onset 1-5 minutes. Do not self-administer IM.

Low: 0.3-0.5mg/kg
Mild dissociation, mood lift. Used in some depression studies.
Common: 0.5-1.0mg/kg
Standard therapeutic dose. Deep dissociation with retained awareness.
Strong: 1.0-1.5mg/kg
Intense dissociation. Standard anesthesia induction range.
K-Hole: 1.5-2.0mg/kg
Complete anesthesia/dissociation. Medical supervision required.

Ketamine Dosage Calculator (Intranasal)





Intranasal Dose
0mg
Common Dose

What Is the K-Hole?

The “K-hole” is a state of profound dissociation where users feel completely detached from their body and surroundings. It is not an overdose—it is a predictable pharmacological effect at higher doses.

What It Feels Like:

  • Complete out-of-body experiences (OBEs)
  • Travel through geometric tunnels or voids
  • Loss of ego and sense of self
  • Time becomes meaningless (minutes feel like hours)
  • Inability to move or speak (temporary paralysis)
  • Profound insights or existential realizations

How to Enter Safely:

  • Lie down in a quiet, dark room before dosing
  • Have a sober sitter present who knows you’re taking ketamine
  • Clear the floor of obstacles—you may attempt to move while dissociated
  • Put on ambient music without lyrics
  • Do not fight the experience. Surrender to the dissociation

Ketamine for Depression & Therapy

Canada has seen rapid expansion of ketamine-assisted therapy since 2020. Clinical protocols differ from recreational use:

  • Spravato (Esketamine): FDA/Health Canada approved nasal spray for treatment-resistant depression. Administered in clinics only.
  • IV Ketamine Infusions: 0.5mg/kg over 40 minutes in medical settings. Typically 6 sessions over 2-3 weeks.
  • Racemic Ketamine: The standard form. Off-label use for depression is growing across Canadian clinics (Toronto, Vancouver, Calgary).

🚨 Ketamine Bladder Damage (K-Bladder)

Chronic ketamine use destroys the bladder lining. This is not reversible in advanced stages.

  • Warning signs: Frequent urination, pain while urinating, blood in urine, reduced bladder capacity, incontinence.
  • Risk threshold: Using more than 1-2 grams per week consistently for months.
  • Prevention: Limit use to once per month maximum. Drink green tea (EGCG) which may protect urothelium. Stay hydrated.
  • If symptoms appear: Stop immediately and see a urologist. Early cessation can reverse mild damage.

Duration & After Effects

Phase Intranasal Oral
Onset 5-15 minutes 15-30 minutes
Come Up 10-20 minutes 20-40 minutes
Peak 20-45 minutes 45-90 minutes
Comedown 30-60 minutes 60-120 minutes
Total Duration 45-90 minutes 90-180 minutes
Afterglow 1-3 hours 2-4 hours

Harm Reduction Essentials

  • Never mix with depressants: Alcohol + ketamine = respiratory depression and vomiting aspiration risk.
  • No stimulants: Cocaine or amphetamines with ketamine strain the cardiovascular system dangerously.
  • Empty stomach: Reduces nausea significantly, especially for oral doses.
  • Don’t walk alone: At common+ doses, you cannot walk properly (K-legs). Sit or lie down.
  • Spit the drip: When snorting, the nasal drip swallowed into your stomach is what damages the bladder. Spit it out.
  • Monthly maximum: To protect your bladder and mind, do not use more than once per month.
📌 Medical Disclaimer

Ketamine is a controlled substance in Canada (Schedule I) and should only be used under medical supervision. Recreational use carries significant risks including addiction, bladder damage, and cognitive impairment. If you or someone you know is struggling with ketamine use, contact your provincial health services or the Canadian Centre on Substance Use and Addiction.

LSD Dosage Guide

Micrograms to milligrams: a complete breakdown of acid potency, effects by dose, and how to navigate every stage of the trip safely.

⚠️ Critical Safety Warning

LSD is a powerful psychedelic. A single tab can last 8-12 hours. You cannot abort the trip once it begins. Do not mix with lithium (seizure risk), tramadol, or stimulants. If you have a family history of schizophrenia or bipolar disorder, avoid LSD entirely. Test your tabs with an Ehrlich reagent kit. This guide is for educational harm reduction only.

LSD Dosage Calculator

LSD is measured in micrograms (ug), not milligrams. A typical blotter tab contains 75-150ug. Because tabs vary wildly in potency, always start with one tab from a new batch.

Come Up 1-2 hours Visuals begin. Colors saturate. Patterns move. Body load peaks. Anxiety may spike—this passes.
Peak 2-5 hours Maximum intensity. Geometric overlays, time distortion, deep thoughts, emotional release.
Plateau 5-8 hours Stable high. Easier to navigate. Conversations flow. Nature feels sacred. Creativity peaks.
Comedown 8-12 hours Gradual return. Visuals fade to “sparkles.” Physical tiredness. Reflective mood.
Afterglow 1-3 days Improved mood, openness, mental clarity. Sleep may be poor the first night.

Set & Setting: The Foundation of a Good Trip

🧠 Set (Mindset)

  • Don’t trip if depressed, anxious, or stressed
  • Have an intention, not an expectation
  • Accept that difficult moments are temporary
  • Remember: you took a drug, it will end

🏠 Setting (Environment)

  • Safe, familiar location for first trips
  • Remove dangerous objects and heights
  • Prepare music playlists in advance
  • Have blankets, water, and fruit nearby

👤 The Sitter

  • Sober, trusted, calm under pressure
  • Knows what you took and when
  • Doesn’t lecture or judge your experience
  • Can call for help if medically needed

🆘 If Things Go Dark

  • Change the room or go outside
  • Put on familiar, comforting music
  • Breathe deeply. Focus on a single object.
  • Remind yourself: “This is temporary”
  • Do NOT call 911 unless physically unsafe

🔄 LSD Tolerance & Frequency

LSD tolerance builds immediately and lasts approximately 14 days. Taking LSD two days in a row requires roughly 2.5x the dose to achieve the same effects. This is not worth it.

  • Minimum: Wait 7 days between trips (still reduced effects)
  • Recommended: Wait 2-4 weeks for full sensitivity reset
  • Optimal: Once per season (4x/year) for mental health benefits
  • Cross-tolerance: Exists with psilocybin, mescaline, and DMT

Testing Your LSD

Never take a tab without testing. NBOMe compounds (25I-NBOMe, 25C-NBOMe) are sold as LSD and have killed people at normal doses.

  • Ehrlich Reagent: Turns purple if an indole (LSD, psilocybin, DMT) is present. Does NOT rule out NBOMe + LSD mixtures.
  • Hofmann Reagent: Turns blue with LSD specifically.
  • Marquis Reagent: NBOMe turns green to black. LSD has no reaction.
  • Bitter taste = Spit it out. Real LSD is tasteless. NBOMe is bitter and numbs the tongue.
📌 Medical Disclaimer

LSD is a Schedule III controlled substance in Canada. Possession is illegal. This guide is for educational and harm-reduction purposes only. If you are experiencing a prolonged psychotic episode or suicidal thoughts after psychedelic use, seek emergency medical help immediately.
