If you’re serious about taking your physique or performance to the next level, chances are you’ve heard of Turinabol—a steroid known for delivering clean, lean gains without the bloating or estrogenic side effects common with other anabolics. But how does it work? Is it safe? And what’s the real best way to use it?
What Is Turinabol? Origins, Chemistry, and How It Works
Turinabol, also known as chlorodehydromethyltestosterone or simply Tbol, is an oral anabolic steroid developed in East Germany during the 1960s under the code name Oral-Turinabol. It was created by modifying Dianabol (methandrostenolone), making it less androgenic and eliminating its tendency to aromatize into estrogen [^1].
Why Was Turinabol Created?
The goal was simple: build stronger athletes without detection.
East German scientists wanted a compound that would enhance strength and endurance but wouldn’t show up easily on early drug tests. Tbol fit the bill—it provided steady muscle growth, improved recovery, and minimal water retention, all while flying under the radar for years [^2].
“Turinabol was central to the state-sponsored doping program in East Germany. Thousands of athletes, including minors, were given it without consent.”
— Dr. Michael Scally, MD, researcher in anabolic steroid-induced hypogonadism Michael Scally – ResearchGate Profile
How Does Turinabol Work in the Body?
Unlike testosterone-based steroids, Turinabol doesn’t convert to estrogen or DHT, which means:
- No gynecomastia
- Minimal acne or hair loss
- Low risk of high blood pressure from water retention
Instead, it binds directly to androgen receptors and increases protein synthesis and nitrogen retention—two key drivers of muscle growth Anabolics by William Llewellyn – ResearchGate . Its anabolic-to-androgenic ratio is estimated at 54:6, making it one of the mildest oral steroids available Steroid.com .
However, despite being “mild,” Turinabol is still hepatotoxic (liver-damaging) because it’s a 17-alpha alkylated compound—a necessary modification for oral bioavailability, but one that stresses the liver Hepatology Journal .
Benefits of Using Turinabol
Why do bodybuilders and performance athletes still use Turinabol today? Because when used correctly, it delivers predictable, high-quality results.
✅ Lean Muscle Gains Without Bloat
Turinabol promotes dry, hard muscle gains—ideal for cutting phases or pre-contest preparation. Unlike Dianabol, which causes significant water retention, Tbol builds quality tissue over time JAMA Study on Anabolic Steroids .
Users typically report gaining 4–8 lbs (2-4 kg’s) of lean mass over an 8-week cycle, depending on diet and training ThinkSteroids Community .
✅ Strength Increases
Even at moderate doses, many users experience noticeable improvements in strength, especially in compound lifts like squats, deadlifts, and bench press PowerliftingToBodybuilding Forum .
This isn’t explosive strength like with Testosterone or Trenbolone—but rather consistent, sustainable progress due to better recovery and increased red blood cell production Endocrine Society .
✅ Enhanced Recovery & Endurance
One underrated benefit of Turinabol is improved aerobic capacity and faster recovery between sets and workouts. This makes it popular among athletes who need to train frequently without burning out Sports Medicine Review .
Animal studies have shown Turinabol increases oxygen uptake and hemoglobin levels, enhancing stamina—an effect noted in both military and athletic applications RAND Corporation Report .
✅ Low Estrogenic Activity
Because Turinabol does not aromatize, users don’t need anti-estrogens (like Arimidex or Nolvadex) during the cycle—unless stacking with other compounds that do UpToDate .
This simplifies cycle management and reduces side effect risks.
Side Effects and Risks: What You Must Know Before Use
No steroid is completely safe. Even “mild” ones like Turinabol carry real risks—especially if misused.
Liver Toxicity
As a 17α-alkylated steroid, Turinabol passes through the liver unchanged so it can remain active orally. However, this places stress on hepatic enzymes.
Clinical data shows elevated liver enzymes (ALT/AST) even at low doses (20–40 mg/day) after just 4 weeks of use Mayo Clinic – Hepatitis Overview . While these often return to normal post-cycle, chronic or high-dose use increases the risk of permanent damage.
Best practice: Limit cycles to 6–8 weeks, avoid alcohol, and use liver support supplements like TUDCA or NAC NIH Study on TUDCA .
Suppression of Natural Testosterone
Like all exogenous androgens, Turinabol suppresses the HPTA (hypothalamic-pituitary-testicular axis), leading to reduced natural testosterone production Cleveland Clinic – Hypogonadism .
In fact, a study published in Endocrine Reviews found that even short-term AAS use can lead to prolonged hypogonadism requiring months of recovery Endocrine Reviews – ASIH Long-Term Effects .
“Anabolic steroid-induced hypogonadism (ASIH) is now seen in recreational lifters, not just pros. Many men come in with low libido, fatigue, depression—and no idea why.”
— Dr. Michael Scally, MD Michael Scally – Anabolic Steroid-Induced Hypogonadism
You must run a proper Post Cycle Therapy (PCT) after any Turinabol cycle.
Cholesterol Impact
Turinabol negatively affects lipid profiles by lowering HDL (“good” cholesterol) and raising LDL (“bad” cholesterol) WebMD – Steroids and Cholesterol .
One clinical trial observed a 30% drop in HDL in male subjects using 40 mg/day for 6 weeks Journal of Clinical Lipidology .
To mitigate this:
- Avoid saturated fats during the cycle
- Increase omega-3 intake (fish oil)
- Monitor blood lipids pre- and post-cycle
Cardiovascular Risk
Long-term cardiovascular effects are understudied, but there’s growing concern about arterial stiffness and endothelial dysfunction linked to oral steroids Harvard Health – Heart Risk .
Turinabol may reduce nitric oxide availability, impairing vasodilation—a key factor in heart health American Journal of Physiology .
Recommended Turinabol Dosage: Men vs Women
Dosage depends on goals, experience level, and tolerance. More is not better.
For Men: 20–50 mg Per Day
Most effective results occur between 30–40 mg/day for 6–8 weeks AnabolicMinds Forum – Dosage Guidelines .
| Dose | Effect | Risk level |
| 20 mg | Mild gains, suitable for first-time users | Low |
| 30–40 mg | Optimal balance of muscle growth and safety | Moderate |
| 50+ mg | Increased gains but significantly higher liver strain | High |
Splitting the dose (e.g., 20 mg morning, 20 mg afternoon) helps maintain stable blood levels due to its ~8-hour half-life Drugs.com – Half-Life Data .
Pro Tip: Start with 30 mg/day for your first cycle. Assess response before increasing. Blood work mid-cycle (Week 4–5) is strongly advised.
For Women: Not Recommended (High Virilization Risk)
While some female athletes historically used Turinabol (especially in East Germany), the risk of virilization—deepening voice, clitoral enlargement, facial hair—is extremely high NIH Report on Virilization .
Even at 5–10 mg/day, irreversible changes can occur within weeks British Journal of Sports Medicine .
There is no safe window for women seeking aesthetic results without major risk.
Below is a summary of potential virilization symptoms and their onset timeline:
| Symptom | Onset time | Reversibility after discontinuation |
| Deepened voice | 2–4 weeks | ❌ Irreversible |
| Clitoral enlargement | 3–6 weeks | ❌ Irreversible |
| Facial/body hair growth | 4–8 weeks | ❌ Mostly irreversible |
| Acne | 1–3 weeks | ✅ Reversible |
| Menstrual irregularities | 2–5 weeks | ✅ Usually reversible |
⚠️ Medical Insight: “Female androgen exposure—even mild compounds like Turinabol—can permanently alter hormone-sensitive tissues. Once voice deepening begins, it rarely resolves.”
— Dr. Michael Scally, MD ResearchGate – Anabolic Steroid-Induced Hypogonadism
Given the high risk, most experts—including Dr. Thomas O’Connor (“The Anabolic Doctor”)—strongly advise against Turinabol use in women The Anabolic Doc Podcast .
Turinabol Cycle Length: How Long Should You Run It?
Given its liver impact, longer is not better.
Ideal Cycle Duration: 6–8 Weeks
- Shorter than 6 weeks → suboptimal results
- Longer than 8 weeks → significantly increased liver strain
Some advanced users extend to 10 weeks, but only with strict liver monitoring and support More Plates More Dates – Cycle Length .
📌 Example 8-Week Turinabol Cycle Plan:
| Week | Turinabol Dosage | Liver support (TUDCA) | Monitoring Notes |
| 1–8 | 40 mg per day | 500 mg, twice daily | Take TUDCA with meals. Begin blood work (liver enzymes, lipids) around Week 4–5. Avoid alcohol and hepatotoxic substances. |
PCT Start: Begin Post Cycle Therapy (e.g., Clomid + Nolvadex) 3 days after the last Turinabol dose.
Why 6–8 Weeks Is the Sweet Spot
| Cycle length | Pros | Cons |
| 4–6 weeks | Lower liver strain, safer for beginners | Suboptimal gains, may not reach peak effectiveness |
| 6–8 weeks | Full expression of gains, manageable liver load | Requires blood work and liver support |
| 8–12 weeks | Slightly more gains possible | Significantly increased risk of liver enzyme elevation, HDL suppression, and hormonal imbalance |
Clinical Insight: A 2020 review in Endocrine Reviews concluded that oral AAS exceeding 8 weeks correlates with a sharp rise in ALT/AST markers and delayed HPTA recovery Endocrine Reviews – ASIH Long-Term Effects .
Takeaway: Respect the compound. Eight weeks is enough to see solid results without pushing your body beyond recovery.
The Best Turinabol Stacks: Safe and Effective Combinations
Turinabol works well alone, but most users stack it with other compounds to maximize results.
⚠️ Never stack multiple oral steroids—they all tax the liver.
Beginner Stack: Tbol + Testosterone (TRT-Level Base)
Many believe Turinabol doesn’t suppress much—but it does. Running solo (“Testless”) leads to low energy, poor mood, and stalled gains.
✅ The smart approach: Add a base of Testosterone Enanthate or Cypionate (100–150 mg/week) to keep hormone levels stable Barbell Medicine Podcast – Hormonal Balance .
| Compound | Dosage | Frequency | Purpose |
| Turinabol | 40 mg/day | Daily | Lean muscle growth, enhanced recovery |
| Testosterone Enanthate | 125 mg | Twice weekly (Mon/Thu) | Maintain physiological testosterone levels, prevent crash |
| TUDCA | 500 mg | Twice daily | Liver protection |
| PCT (Post-Cycle) | Clomid 50 mg/day → taper over 4 weeks | Days 3–30 post-last dose | Restart natural testosterone production |
This combo gives solid lean gains with manageable side effects.

Intermediate Stack: Tbol + Test + Winstrol (Cutting Focus)
For competition prep or fat loss phases, adding Winstrol enhances hardness and vascularity.
Both are non-aromatizing, reducing estrogen concerns.
| Compound | Dosage | Frequency | Purpose |
| Turinabol | 30 mg/day | Daily | Lean mass preservation |
| Testosterone Propionate | 100 mg | Every other day | Stable TRT-level support |
| Winstrol (Injectable) | 50 mg | Every other day | Vascularity, fat loss, dry look |
| TUDCA | 500 mg | Twice daily | Liver support |
| Fish Oil | 3–4 g/day | Daily | Counteract cholesterol drop |
💡 Pro tip: Lower Tbol dose when stacking with another oral (if using oral Winstrol) to protect the liver.
Winstrol further lowers HDL, so monitor cholesterol closely Medscape – Winstrol Overview .
Advanced Lean Mass Stack: Tbol + Test + Anavar
For maximum dryness and definition, Anavar complements Turinabol perfectly.
Anavar has mild anabolic effects but excellent fat-burning properties and improves vascularity Journal of Clinical Endocrinology & Metabolism .
| Compound | Dosage | Frequency | Purpose |
| Turinabol | 30 mg/day | Daily | Quality lean gains |
| Testosterone Cypionate | 150 mg | Twice weekly | Hormonal stability |
| Anavar (Oxandrolone) | 40 mg/day | Split AM/PM | Fat oxidation, vascularity boost |
| TUDCA | 1000 mg/day | Split AM/PM | Mandatory liver protection |
| CoQ10 + Omega-3 | Daily | With meals | Cardiovascular support |
Note: Both Tbol and Anavar are 17aa orals → liver support is mandatory.
Use TUDCA (500–1000 mg/day) throughout and consider mid-cycle bloodwork Ben Greenfield Fitness – Liver Support .
❌ Dangerous Stacks to Avoid
🚫 Tbol + Dianabol: Two 17aa orals = extreme liver stress
🚫 Tbol + Anadrol: Same issue—double hepatotoxic load
🚫 Tbol + Superdrol: Extremely toxic; only for experienced users under medical supervision
These combinations dramatically increase the risk of acute liver injury—even in healthy individuals Toxicology Reports – Superdrol Toxicity .
Below is a comparison of common dangerous oral stacks:
| Combination | Liver toxicity risk | Cholesterol impact | Recommended? |
| Tbol + Dianabol | ⚠️⚠️⚠️ High | Severe HDL drop | ❌ No |
| Tbol + Anadrol | ⚠️⚠️⚠️ Very High | Extreme lipid disruption | ❌ No |
| Tbol + Anavar | ⚠️⚠️ Moderate (with support) | Moderate HDL reduction | ✅ Yes (with monitoring) |
| Tbol + Winstrol (oral) | ⚠️⚠️⚠️ High | Severe lipid issues | ❌ Avoid |
| Tbol + Injectable Winstrol | ⚠️ Moderate | Manageable with fish oil | ✅ Yes |
⚠️ Expert Warning: “Combining two 17-alpha alkylated orals is one of the fastest ways to land yourself in a liver clinic.”

Post Cycle Therapy (PCT): How to Recover Naturally
After suppressing your natural testosterone production, you must restart it—or face months of low energy, depression, and muscle loss.
When to Start PCT
Turinabol clears the system quickly (half-life ~6–8 hours). Begin PCT 3 days after last dose.
Standard PCT Protocol
This protocol stimulates LH and FSH release, signaling the testes to resume testosterone production RXMuscle – PCT Mechanism .
“Without PCT, you’re leaving your hormonal recovery to chance. That’s how people end up needing TRT.”
— Dr. Thomas O’Connor (“The Anabolic Doctor”) The Anabolic Doc Podcast
Check your bloodwork before and after PCT to confirm recovery.
Detection Time and Drug Testing
Turinabol is banned by WADA and most sports organizations. It can be detected in urine for up to 18 months in some cases due to long-lived metabolites World Anti-Doping Agency (WADA) .
Recent advances in gas chromatography-mass spectrometry (GC-MS) allow detection of trace metabolites long after use Journal of Analytical Toxicology .
🚫 If you compete in tested sports, Turinabol is not worth the risk.
Even microdosing leaves detectable traces.
Real User Experiences: What People Say About Turinabol
Let’s look at real-world feedback from forums, podcasts, and expert reviews.
From Reddit (r/Steroids, r/PEDTalk):
“Ran 40 mg Tbol + 125 mg Test for 8 weeks. Gained 6 lbs of solid muscle, strength up across all lifts. No sides except slightly yellow pee. PCT worked fine.” – u/BulkModeActivated Reddit – r/Steroids Thread
“Used Tbol pre-contest. Skin was tight, veins popped, looked amazing on stage. But my HDL dropped to 28. Won’t do it again without better cardio/lipid control.” – u/FitnessGearedPro FitnessGeared Forum
From Podcasts
On The Mind Pump Show, Sal Di Stefano said:
“Turinabol is one of the few orals I’d consider ‘clean.’ It doesn’t make you feel bloated or sluggish. But respect the liver. Always.” Mind Pump Media – Episode #887
Greg Doucette has warned against solo Tbol cycles:
“People think Tbol isn’t suppressive. Wrong. You WILL crash without PCT or a Test base.” Greg Doucette – YouTube Video
Alternatives to Turinabol: Safer Options?
If you want similar benefits without the legal or health risks, consider:
Legal Supplements (Limited Evidence)
- Laxogenin – plant-based compound claimed to boost protein synthesis
- Ecdysterone – studied for potential anabolic effects; weak compared to AAS Archives of Toxicology – Ecdysterone Study
- Tongkat Ali + Fadogia Agrestis – popular in natural communities, though human data is lacking NIH – Fadogia Animal Study
None match Turinabol’s potency.
Peptides & SARMs (Gray Area)
- Ostarine (SARM) – mild lean gains, but recently linked to liver issues FDA Warning Letters
- IGF-1 LR3 – powerful but requires careful dosing and refrigeration NIH – IGF-1 Research
Still largely unregulated and not FDA-approved.
