Etomerzol, an unapproved synthetic research chemical related to the Soviet performance drug bemitil, was designed to keep people functioning under oxygen shortage, heavy exertion and poisoning.

Injection-site tissue injury is the clearest recorded harm; no long-term safety or longevity evidence exists. (Full Review)
| Marker | Target | Why |
|---|---|---|
| ALT | 10–25 U/L | Liver-cell injury |
| AST | 10–25 U/L | Liver and muscle injury |
| Total bilirubin | 0.3–1.0 mg/dL | Liver processing capacity |
| Creatinine with eGFR | eGFR above 90 mL/min/1.73 m² | Kidney clearance of the drug |
| Fasting glucose | 75–90 mg/dL | Detects low or unstable blood sugar |
| Platelet count | 150–350 ×10⁹/L | Baseline clotting-cell supply |
| Blood pressure | Below 120/80 mmHg, systolic above 100 | Detects additive lowering |
Cadence: Baseline panel before any course; home blood pressure and fasting glucose daily on days 1–3; repeat liver and kidney panels at the end of each 7–10 day course; full baseline panel repeated before any further course, spaced at least 4–6 weeks apart
