Turinabol (4-Chlorodehydromethyltestosterone) — Dosing, Cycles, Half-Life & Side Effects
Turinabol (4-Chlorodehydromethyltestosterone) is an oral anabolic-androgenic steroid with a half-life of ~16 hours. Oral DHT derivative developed for performance enhancement. Known as 'Dianabol without water retention'. 17α-alkylated with moderate hepatotoxicity. Very long detection window (up to 12 months). Primary risks include liver stress typical of 17α-alkylated orals.

Cycle length: 6-8 weeks
Time to steady state: ~3 days
Dose ranges are compiled from published pharmacokinetic studies and community-reported usage. Where a value is community-reported rather than clinically studied, this page and its structured data flag it. Lower end of any range is always the safer starting point.
Stacking Considerations
- Do not stack with another 17α-alkylated oral. Dual-17αα stacking is prohibited in StackItSmart and unsafe for the liver.
PCT Requirements
- This compound causes clinically meaningful HPTA suppression. Post-cycle therapy is recommended.
- Depot clearance estimate: ~3 days post-last-dose before SERM start (5 × apparent depot half-life of 16h).
- Never stack two SERMs. Extend a single SERM (tamoxifen OR enclomiphene/clomiphene) rather than combining.
- Use the cycle planner to generate a full protocol based on your complete stack, not this compound alone.
Side Effect Profile
- Moderate liver toxicity (17α-alkylated)
- Extremely long detection window (12 months)

Monitoring (Bloodwork & Vitals)
- Comprehensive metabolic panel (baseline, mid-cycle, post-cycle)
- Lipid panel (total cholesterol, HDL, LDL, triglycerides)
- CBC (hemoglobin, hematocrit — watch for erythrocytosis)
- Sex-hormone panel (Total T, Free T, Estradiol sensitive, SHBG, LH, FSH)
- Liver enzymes (ALT, AST, GGT) every 2–4 weeks on oral 17αα cycles
- Blood pressure (weekly self-check; flag systolic >140 or diastolic >90)
Baseline bloodwork is recommended before any cycle. Discontinue if liver enzymes exceed 3× upper limit of normal or if hematocrit exceeds 54%.
Frequently Asked Questions
What is the half-life of Turinabol (4-Chlorodehydromethyltestosterone)?
Turinabol (4-Chlorodehydromethyltestosterone) has a half-life of approximately ~16 hours. Clearance estimate: 16h � 5 = 80h = 3.3 days. This figure is used to determine injection frequency (for esters) and post-cycle clearance timing.
What is the typical dose range for Turinabol (4-Chlorodehydromethyltestosterone)?
Commonly reported ranges for Turinabol (4-Chlorodehydromethyltestosterone): 30-60mg/day (males), 2.5-5mg/day (females). Cycle length: 6-8 weeks. These are compiled from published studies and community-reported usage — individual response varies and lower end is always preferred.
Does Turinabol (4-Chlorodehydromethyltestosterone) suppress natural testosterone?
Turinabol (4-Chlorodehydromethyltestosterone) causes strong suppression of the HPTA axis (score 6/10). Post-cycle therapy (PCT) is recommended after use.
Is Turinabol (4-Chlorodehydromethyltestosterone) liver toxic?
Hepatotoxicity rating: Moderate. Turinabol (4-Chlorodehydromethyltestosterone) is 17α-alkylated, which bypasses first-pass liver metabolism and increases hepatic stress. Oral 17αα cycles should be capped at 6 weeks and paired with liver monitoring (ALT/AST every 2–4 weeks).
Does Turinabol (4-Chlorodehydromethyltestosterone) aromatize to estrogen?
Aromatization profile: No. Minimal to no aromatization expected, so aromatase inhibitors are not typically indicated for this compound alone.
What is Turinabol (4-Chlorodehydromethyltestosterone) typically used for?
Turinabol (4-Chlorodehydromethyltestosterone) is commonly used for: Cutting, Athletic performance, Recomposition, Intermediate to advanced users. Intended-use context does not imply safety — every use case carries the same underlying pharmacological risks.
