FAQ.
- What is a safe Anfetamina dose?
- A "safe" dose depends on body weight, tolerance, set and setting. Start at the threshold or light range for your chosen route and do not redose until onset is complete.
- How do I calculate Anfetamina dose by weight?
- For substances where bodyweight matters: divide the mg amount by your weight in kg to get the mg/kg ratio. Most common dose data assumes a 70–80 kg adult.
- What happens if I take too much Anfetamina?
- Exceeding the "heavy" range significantly increases risk of adverse effects, medical emergency, or overdose. Harm reduction starts with knowing the ranges.
- How long does Anfetamina last?
- Duration varies by route. The timeline section below shows onset, peak, offset and after-effects for each route.
- Can I mix Anfetamina with other substances?
- Many combinations are dangerous. Check the interaction checker tool before combining anything. Never combine on a first experience.
- Is Anfetamina dosage the same for all routes?
- No. Bioavailability differs significantly by route — intranasal and IV routes typically require lower doses than oral for equivalent effect.
- Should I weigh my Anfetamina dose?
- Always. A milligram scale (0.001g precision) is essential for most substances. Volumetric dosing with a solvent is the gold standard for sub-10mg doses.
