Ketamine Dosage Guide — Buying Ketamine Online in Canada

Ketamine sits in its own category — dissociative rather than psychedelic, medically approved, and dose-dependent in a way that makes it both remarkably useful and remarkably easy to misuse. This guide covers the dosing you actually need.
What is ketamine?
Ketamine is an NMDA-receptor antagonist first synthesised in 1962 and used as a battlefield anaesthetic ever since. At sub-anaesthetic doses it produces dissociation, mild euphoria, and — increasingly documented in the last decade — rapid, robust anti-depressant effects. Duration is short (45–90 minutes), which is part of what makes it so different from classic psychedelics.
Routes and dose ranges
Doses vary dramatically by route. Numbers below assume racemic ketamine and are per session, not cumulative:
Insufflated (snorted)
- Threshold: 10–25 mg
- Light: 25–50 mg (musical trance, mild dissociation)
- Common: 50–100 mg (deeper dissociation, body-heavy)
- Strong: 100–150 mg (approaching k-hole)
- K-hole: 150 mg+ (full dissociation, immobility, ego dissolution)
Oral (much less efficient, longer onset)
- Light: 75–150 mg
- Common: 150–300 mg
- Strong: 300–500 mg
Onset: 5–15 minutes insufflated, 20–30 minutes oral. Peak lasts 30–45 minutes; full return to baseline within 2–3 hours.
What a k-hole actually is
At 150+ mg insufflated, most users cross a threshold where motor control drops, sensory input decouples from the body, and consciousness moves through what feels like an entirely different reality. It’s not dangerous when done seated or lying down in a safe environment, but attempting to walk, drive or make decisions in this state is where injuries happen. Never k-hole alone or standing up.
Addiction risk — the honest version
Ketamine is one of the more habit-forming substances we sell. The short duration and manageable comedown make it easy to redose, and daily-user tolerance climbs fast. Rules that keep people safe:
- Maximum one session per week — never two in a row.
- Never redose more than twice within a single session.
- If you find yourself planning your week around ketamine, that’s the warning sign — talk to a professional.
- Heavy long-term use is associated with severe bladder damage (ketamine cystitis). Weekly recreational use won’t cause it; daily use will.
Combinations to avoid
- Alcohol (respiratory depression, blackouts).
- Opioids and benzodiazepines (respiratory depression).
- Other dissociatives (unpredictable).
- MDMA (cardiovascular strain, temperature dysregulation).
Sourcing safely in Canada
Ketamine is Schedule I in Canada, tightly regulated in medical settings. Buying from a discreet Canadian source with lab-verified product is dramatically safer than street sourcing, where cuts with fentanyl analogues, MXE and other dissociatives have all been documented. All ketamine shipped from our facility is pharmaceutical-grade and tested. Delivery is Canada Post Xpresspost, 1–3 business days, discreet packaging, tracked. Pay by Interac e-Transfer or Bitcoin (10% off).
