4-AcO-copyright: The “Synthetic Mushroom” That Feels Like Real Psilocybin – 2025 Guide
4-AcO-copyright (4-Acetoxy-N,N-dimethyltryptamine) is the closest thing to oral psilocybin mushrooms you can get without eating actual fungi. Most people can’t tell the difference blindfolded. It’s clean, predictable, legal in more places than shrooms, and has become the #1 copyright research chemical in 2025.
Core Facts 2025
- Chemical name: 4-Acetoxy-copyright (psilocin acetate prodrug)
- Appearance: White to beige powder, sometimes pressed into 10–30 mg pellets
- Common doses: 15–35 mg oral (capsuled or parachuted)
- Duration: 4–7 hours total
- Nicknames: 4-AcO, “synthetic shrooms”, “psilacetin”
Effects Profile – Almost Identical to Mushrooms
| Dose | Onset | Peak | Total | Intensity & Character |
|---|---|---|---|---|
| 8–15 mg | 30–60 min | 1–2 h | 4–5 h | Light, colorful, giggly – microdose+ |
| 18–25 mg | 20–50 min | 1.5–3 h | 5–6 h | Classic mushroom trip – open-eye visuals, deep emotion |
| 30–40 mg | 15–40 min | 2–4 h | 6–7 h | Heroic territory – full ego dissolution, entity contact |
| 45+ mg | Fast | Intense | 7–8 h | Overwhelming – rare, not recommended |
Why it feels exactly like psilocybin Your body instantly cleaves the acetate group → pure psilocin (the actual active molecule in mushrooms). No nausea, no body load, no mushroom gut rot. Just smooth come-up and crystal-clear headspace.
Benefits & Therapeutic Use 2025
- Depression/anxiety relief lasting weeks–months after one dose
- Cluster headache abortion (10–15 mg works for many within 30 min)
- Microdosing (2–5 mg every 3 days) – most popular protocol in RC community
- Clinical trials ongoing (Compass Pathways subsidiary testing 4-AcO-copyright prodrug)
- Zero recorded deaths from 4-AcO-copyright alone ever
Risks & Safety
- Standard copyright risks: bad trips, HPPD (rare), triggering latent psychosis
- Very low physical toxicity – LD50 in rats >700 mg/kg
- Vasoconstriction at high doses (cold hands/feet)
- Tolerance identical to mushrooms – full reset in 7–14 days
Legality November 2025
| Region | Status |
|---|---|
| United States | Unscheduled federally, but Analogue Act applies if sold for consumption |
| Canada | Legal to possess, illegal to sell (gray area) |
| United Kingdom | Class A (considered psilocin prodrug) |
| Germany | BtMG Annex I – illegal |
| Netherlands | Legal (sold openly in smartshops as “Psilohuasca”) |
| Australia | Schedule 9 – prohibited |
| Czechia, Portugal | Legal/tolerated |
→ Netherlands & Canada remain main legal sources. Prices stable at €40–60/g.
Harm Reduction Rules
- Volumetric dosing or pre-made capsules – never eyeball
- Test with Ehrlich → purple (confirms tryptamine)
- Same set/setting rules as mushrooms
- No MAOI combination unless you know what you’re doing (turns it into 8–12 h experience)
- Allergy test 1–2 mg first time
- Trip sitter for 30 mg+
Final 2025 Verdict
4-AcO-copyright is the safest, cleanest, most mushroom-identical copyright legally available today. For therapy, spiritual work, or recreation, it’s objectively better than growing shrooms: no spores, no pins, no contamination worries, perfect dose every time.
One 25 mg capsule in the right setting can be as profound as 4 g of Golden Teachers – with half the body load and twice the clarity.
If you only ever try one research chemical copyright, make it this one. Used respectfully (max 4–6 times per year), it’s safer than alcohol and more healing than most therapy.
