Full 2C-B-FLY profileImportant Safety Notice
Dosage information is for harm reduction purposes only. Individual sensitivity varies greatly. Always start with the lowest effective dose and work your way up slowly. Never eyeball doses — use a milligram scale.
Fatal overdose from 2C-B-FLY alone, at doses within the typical recreational range, is extremely unlikely based on the available evidence for classical psychedelics. The therapeutic index for most psychedelics is very wide. However, **psychological emergencies** can occur and require appropriate response: - Severe anxiety, panic, or psychotic episodes - Dangerous behavior due to impaired reality testing - Self-harm in the context of a distressing experience **Emergency management**: If someone is experiencing a severe adverse reaction, move them to a calm, quiet environment. Speak reassuringly. Do not restrain unless there is immediate danger. Benzodiazepines (if available and the person is conscious and able to swallow) can reduce acute anxiety. If psychotic symptoms, self-harm risk, or medical distress is present, seek emergency medical attention. **Medical attention**: Seek help immediately for seizures, extremely elevated body temperature, signs of serotonin syndrome (agitation, tremor, diarrhea, rapid heart rate), or if the substance consumed is uncertain.
A common oral dose of 2C-B-FLY is 10–18 mg.
The threshold dose for 2C-B-FLY via oral is approximately 2 mg.
2C-B-FLY typically lasts 7–12 hours via oral.
