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.

Typical Dosing Ranges

Common dose range: 30-60mg/day (males), 2.5-5mg/day (females)

Cycle length: 6 weeks max

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

Known Interactions

No compound-specific interactions are catalogued in the current matrix. This does not mean no risk exists — it means there is no curated pairwise entry.

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 weeks max. 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.
