Summary
Sold solely as a research chemical with no quality control or clinical data in humans. SR-17018 is not orally bioavailable when dissolved in water due to poor solubility; must be taken as powder or with appropriate excipients. Primarily reported for opioid tapering due to craving suppression and tolerance reduction properties, not recreation.

|---|---|---|---|---|
| Oral | 15-45 min | 30-60 min | 1-3 hrs | 4-6 hrs |

Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Moderate euphoria and itching/nausea with mild pain relief, low sedation
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session β the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Model reflects preclinical evidence for relatively slower tolerance build than morphine in some assays and community reports of tolerance reduction during SRβ17018 use; human kinetics unknown. Values are heuristic for harmβreduction planning, not physiological truths.
