When we stopped foraging and started building.

Four compounds, four very different histories, and the century's most consequential bicycle ride.

Every other page on this site is about finding something. This one is about making it.

The change is bigger than it sounds. A plant gives you what it gives you. A laboratory gives you whatever you can draw — including molecules that have never existed, in doses no plant would produce, at a purity nothing in nature bothers with.

That cuts in both directions, and this page will say so.

LSDThe famous miscalculation

Albert Hofmann synthesized it in November 1938 and set it aside for five years. He came back to it on 16 April 1943, absorbed a trace through his skin, and found the afternoon becoming strange.

Three days later he did it deliberately. 19 April 1943, four-twenty in the afternoon, 250 micrograms — a dose he believed was the smallest that could possibly have an effect. He then cycled home.

He was wrong by a factor of several. 250 micrograms is not a threshold dose; it is a substantial one. The most famous experiment in this entire field was a miscalculation, and the bicycle ride that followed has been commemorated ever since as Bicycle Day.

Sandoz marketed it as Delysid from 1947. More than a thousand papers followed. Cary Grant spoke openly about roughly a hundred sessions. MK-Ultra began in 1953 and ended in the death of Frank Olson. Leary and Alpert arrived at Harvard in 1960 and were both gone by 1963.

Hofmann died in 2008, aged 102.

MDMASixty years on a shelf

First made at Merck in 1912 and patented in 1914, then left completely alone for six decades. Nobody knew what it did because nobody looked.

Shulgin synthesized it in 1976 and introduced it to Leo Zeff, a therapist who is estimated to have shown it to over four thousand other therapists. The DEA scheduled it in 1985.

MAPS was founded by Rick Doblin in 1986, one year after scheduling, and spent the next four decades on the problem. Phase 3 results came in 2021 and 2023. An FDA advisory committee voted against in June 2024, and a Complete Response Letter followed that August.

That is where the story currently sits. Not a triumph, not a defeat. Thirty-eight years of work meeting a regulator that wanted different evidence.

KetamineThe one you can actually get

Synthesized by Calvin Stevens at Parke-Davis in 1962 and FDA-approved as an anaesthetic in 1970. Yale's antidepressant finding came in 2000. Esketamine was approved in March 2019.

It is Schedule III. That single fact is why it is the one you can walk into a clinic and receive, while everything else on this page requires a trial, a permit or a plane ticket. The pharmacology did not decide that. The paperwork did.

ShulginOver two hundred compounds

Alexander Shulgin synthesized more than 200 novel compounds, most of them tested first on himself and his wife Ann. PiHKAL (1991) documents 179. TiHKAL (1997) adds 55 more. Both books publish the full synthesis.

The DEA raided him in 1994. He died in 2014, aged 88.

The dark side, stated plainly

The same capability that produces a clean, standardized, lab-verified compound also produces the NBOMe family — sold as LSD, active at microgram doses, and lethal at margins LSD does not have.

Blotter paper is blotter paper. It does not announce what is on it. This is the clearest case in the book of a risk created entirely by prohibition rather than by chemistry: an unregulated market cannot label anything honestly, because labelling it honestly is itself a crime.

Where do you land on that? It is genuinely one of the most interesting and consequential questions anyone is asking right now.

A note on the numbers below. Doses and timings are reported from the published clinical and toxicological literature, and they are here so you can read a headline or a trip report accurately. This is education, not instruction, and it is not medical advice.

EXPERIENCE

LSD

A powerful alteration of reality from every vantage point at once: perception, thought and mood. The LSD experience is highly unpredictable and shifts with dose, mental state (“set”) and environment (“setting”). A typical oral dose of 50 to 200 micrograms starts working within 30 to 90 minutes, peaks at around 2 to 4 hours, and can last up to 12 hours in total.

The stages

  1. 30–90 minThe Onset

    A slight tingling, a feeling of anticipation, and subtle changes in lighting and color.

  2. 2–4 hoursThe Peak

    The most intense phase. Sensory distortion, colors exploding, profound shifts in thinking, and emotional highs and lows arriving simultaneously.

  3. 6–12 hoursThe Come Down

    The intense effects slowly fade. The mind reconnects with ordinary reality, and a feeling of exhaustion is very common.

Core sensory and psychological effects

  • Visual distortions. Objects may look like they are breathing, melting or swirling. Colors appear vibrant or leave glowing trails.
  • Synesthesia. A crossover of the senses. A person might feel as though they can see a sound or hear a color.
  • Altered time and space. Minutes can feel like hours. Nearby objects may look impossibly far away, or change size.
  • Ego dissolution. The boundary between the self and the outside world blurs, which can bring a profound sense of unity with nature or the universe.
  • Rapid emotional shifts. Emotions can swing from intense joy to deep sadness or fear in a very short period.
Good

Euphoria and connection, vibrant visuals, synesthesia, profound insight, and high physical energy.

Bad

Panic and paranoia, unpleasant thought loops, frightening hallucinations, distress at the time distortion, and delusions that can put you in danger.

Because LSD severely impairs judgment, the psychological experience can turn sharply positive or negative. The data across the major epidemiological surveys and clinical studies shows a clear trend: the large majority of LSD experiences are reported as positive, and a bad trip is closer to a lifetime event, encountered at least once by roughly a third of users across many uses.

EXPERIENCE

MDMA

Not a psychedelic, and the difference matters. MDMA floods your synapses with serotonin, dopamine and norepinephrine, producing connection rather than distortion. Clinical doses run 75 to 125 mg, with an optional half dose 90 to 120 minutes later. Onset takes 30 to 60 minutes, and the subjective effects average around four hours.

The stages

  1. 30–60 minThe Come-Up

    A rush, sometimes with nausea, then a wave of warmth and the distinct sense that everything has just become fine.

  2. 2–3 hoursThe Plateau

    Enormous emotional openness, physical pleasure and talkativeness, with essentially no visual distortion. You remain entirely yourself, which is the whole clinical point.

  3. 4–6 hours, and the days afterThe Comedown

    Effects fade into fatigue. Transient monoamine depletion can leave mood flat for a day or two afterward.

Core sensory and psychological effects

  • Empathy and trust. The defining effect, and the reason the PTSD trials use it. Frightening memories can be approached without the usual alarm going off.
  • Physical euphoria. Touch, music and movement all become intensely pleasurable.
  • Jaw clenching and dilated pupils. Bruxism is near-universal and thoroughly unglamorous.
  • Cardiovascular load. Temporarily raised blood pressure in about a third of clinical participants, and raised heart rate in nearly as many.
  • Overheating. Body temperature above 38°C in roughly a fifth. Combined with dancing and dehydration, this is the mechanism behind most MDMA deaths.
Good

Warmth, trust, emotional access without fear, the ability to talk about things you cannot normally talk about, and clinical results that are genuinely remarkable.

Bad

Anxiety and racing heart, overheating, dehydration or over-hydration, a flat couple of days afterward, and a street supply that frequently is not MDMA at all.

Every impressive number attached to this compound comes from a clinical setting with a known dose, a screened participant and a cool room. Not one of those conditions describes a festival.

EXPERIENCE

Ketamine

A dissociative rather than a psychedelic, and the only one here you can access legally in all fifty states. An FDA-approved anesthetic since 1970, used off-label for depression at sub-anesthetic doses, typically 0.5 mg/kg infused over 40 minutes. Perceptual effects fade within 10 to 20 minutes of the drip stopping, and most side effects have resolved within two hours.

The stages

  1. 5–15 min inThe Separation

    The body starts reporting in from further away. Limbs feel long, sound acquires an echo, and the room tilts fractionally.

  2. 20–40 minThe Dissociation

    The peak. Detachment from the body, from the self, and from the emotional weight of your own problems. At higher recreational doses this deepens into the immobile, disembodied state users call a k-hole.

  3. 45 min–2 hoursThe Return

    Reassembly. Wobbly, sometimes nauseous, often unusually light. The antidepressant effect frequently arrives hours later rather than during.

Core sensory and psychological effects

  • Dissociation. The core effect. A sense of watching yourself from outside, or of being unable to locate yourself at all.
  • Distorted body schema. Limbs that feel enormous, absent, or as though they belong to somebody else.
  • Analgesia. It is an anesthetic first. Pain stops mattering.
  • Emotional distance. Distressing thoughts stay visible but lose their grip. That gap is the therapeutic window.
  • Blurred vision, dizziness and nausea. The most common clinical side effects, and typically mild.
Good

Rapid relief in treatment-resistant depression, sometimes within hours, a genuinely legal route, and profound relief from both pain and rumination.

Bad

Dysphoria, nausea, raised blood pressure, frightening dissociation, a real dependence risk with repeated recreational use, and bladder damage that is severe and permanent in heavy users.

This is the one with an actual regulator, a complaints process and a license that can be revoked. That is worth more than it sounds. See finding a practitioner.

Chapter Eight covers all four compounds properly, plus the sidebar on how to read a trip report — which exists because this is the chapter where reading them carefully matters most.
