⚠ Important

This information is for educational and harm reduction purposes only. Individual tolerance varies based on body weight, metabolism, experience level, and other factors. Start low, go slow, and never combine substances. If you or someone you know is experiencing an emergency, call 911 immediately.

We include condensed dosage cards with every order, but this page goes deeper. These ranges are based on published research, community reports, and medical literature — not dealer folklore. Use this as a starting point, not a guarantee.

Set and setting matter more than dose. Comfortable environment, trusted company, no obligations for 8+ hours. Have water, light snacks, and a sober sitter if exploring higher doses.

Ketamine

Onset: 5–15 minutes (nasal). Peak: 20–60 minutes. Total duration: 45–90 minutes.

LevelDose (nasal)Experience

Spacing: Allow 2–3 weeks between sessions to prevent bladder toxicity and tolerance buildup. Ketamine is relatively safe physically but psychological dependence is possible with frequent use.
