A one-screen quick reference. Screenshot it and keep it.
| Step | What to do |
|---|---|
| Test first | Reagent kit and a fentanyl strip. No reagent finds fentanyl. Not what you expected? Don't take it. |
| Dose low | Roughly 1-1.5 mg/kg, under ~120 mg. Take a test dose, then wait. |
| Don't chase it | One small top-up at most. Redosing drives the worst comedown. |
| Never mix | MAOIs (can be fatal), SSRIs/SNRIs, tramadol, high-dose stimulants. Careful with alcohol. |
| Stay cool | Breaks from dancing. Sip ~250-500 ml/hour with electrolytes. Not more. |
| The days after | Sleep, food, downtime. A low around day 5 is normal. Don't stack another session. |
| Emergency | Overheating, confusion, seizures, won't wake? Call emergency services now and say what was taken. |
