Tilmetamine
Summary
Tilmetamine (2-(methylamino)-2-(thiophen-2-yl)cyclohexan-1-one) is the N-methyl homolog of Til-ET-amine that reached grey-market vendors in 2024. Community reports place potency roughly five to seven times that of ketamine: 2-5 mg insufflated already produces dissociation, while 10-20 mg has left users with vertigo, tremor, depersonalisation, and dysphoria lasting days. The powder is hygroscopic and clings electrostatically, so volumetric dosing in PG or an ethanol-water mix (for example 10 mg/mL) is far safer than chasing individual milligram shards.

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Strong dissociative depth and motor impairment with mild mania, low insight
Tolerance
Tolerance Decay
Rapid tolerance buildup is frequently reported with arylcyclohexylamines; figures are qualitative and based on community patterns rather than formal PK. Space sessions by several weeks to reduce risk of lingering adverse effects.
