Summary
4-Bromoamphetamine is a stimulant amphetamine. Reported effects include euphoria, color enhancement, time distortion, and wakefulness. Limited data is available on its dosage and safety profile.
Dose Information
Dose basis. No validated human dosing in the literature. Any values below are anecdotal and high-risk. Due to demonstrated serotonergic neurotoxicity of para-halogenated amphetamines in animals and strong community warnings, non-use is the safest choice; if someone proceeds despite risks, dose extremely cautiously, avoid redosing, and use a milligram-accurate scale. (Dose figures and this note are from Drugs.Wiki.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 5-10mg | 10-20mg | 20-30mg | 30mg+ |
Onset, Duration & After-effects
| ROA | Onset | Peak | Offset | Total |
|---|---|---|---|---|
| Oral | 20-60 min | 1-3 hrs | 2-4 hrs | 4-8 hrs |

Strong euphoria and anxiety/jitters with moderate focus and stimulation
Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 4-Bromoamphetamine there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
4-Bromoamphetamine Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 5 · light 5-10 · common 10-20 · strong 20-30 · heavy 30+ Oral duration: onset 0.33-1h · peak 1-3h · offset 2-4h · total 4-8h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 15 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance
Tolerance Decay
Subjective stimulant tolerance builds quickly with repeated use; for serotonergic neurotoxicity risk, any frequency of use increases harm potential; long inter-dose intervals (weeks) are prudent if one does not abstain. Data quality is largely anecdotal due to minimal human data for 4-BA.
