In the 1970s, East German swimmers were given a mysterious new drug called Oral-T—a synthetic steroid later known as Turinabol. Under state-mandated doping programs like State Plan Research Theme 14.25, young athletes achieved world records while secretly enduring liver damage, hormonal collapse, and lifelong health consequences. Their bodies paid the price long after their medals faded.
Today, decades after its discontinuation, Turinabol (Tbol) remains one of the most sought-after oral anabolic steroids in bodybuilding circles—marketed as “mild,” estrogen-free, and ideal for first-time users. But is it truly safe?
Turinabol, chemically known as chlorodehydromethyltestosterone, was developed in East Germany during the Cold War as part of a covert performance-enhancing program targeting Olympic athletes. It was a hybrid compound—derived from Dianabol (methandrostenolone) and Clostebol (4-chlorotestosterone)—designed to deliver steady muscle gains without estrogenic side effects like water retention or gynecomastia.
Unlike other steroids that caused obvious physical changes, Turinabol allowed athletes to enhance performance discreetly—a key reason it became central to the East German doping scandal, which came to light only after the fall of the Berlin Wall.
Despite being discontinued by its original manufacturer, Jenapharm, Turinabol lives on through underground labs (UGLs) and black-market suppliers. Its reputation as a “clean” or “beginner-friendly” steroid continues to attract fitness enthusiasts, bodybuilders, and athletes seeking lean mass with minimal visible sides.
So why does Turinabol still command such loyalty among modern users?
Here are the main reasons:
Because of these traits, Turinabol is often recommended—even informally—as a first steroid cycle option. But this perception may be dangerously misleading.
As we’ll explore next, just because a drug feels gentle doesn’t mean it’s harmless.
All oral anabolic steroids carry a warning label: they are hepatotoxic due to the C17-alpha alkylation process required for oral bioavailability. Turinabol is no exception.
While some claim it’s “easier on the liver” than Dianabol or Anadrol, William Llewellyn, renowned researcher and author of Anabolics, warns:
“All C17-aa orals carry hepatic risk. Turinabol may be less toxic than Dianabol, but it’s not harmless—especially over time.”

A post on r/steroids highlights how easily things can go wrong:
“I ran 40mg Tbol for 6 weeks thinking it was ‘light.’ My ALT jumped to 180. Scared the hell out of me.”

Elevated ALT and AST levels indicate liver stress. While reversible in most cases, prolonged use increases the risk of permanent damage.

Even though Turinabol isn’t highly androgenic, it fully suppresses natural testosterone production via inhibition of the hypothalamic-pituitary-testicular axis (HPTA).
This happens faster than many realize—often within the first two weeks of use.
To illustrate the impact, consider this de-identified example based on aggregated data from forums like AnabolicMinds and third-party lab results:
| Hormone | Pre-cycle | Post-Cycle |
| Total Testosterone | 520 ng/dL | 180 ng/dL |
| ALT | 32 U/L | 110 U/L |
| HDL | 58 mg/dL | 34 mg/dL |
| LDL | 90 mg/dL | 130 mg/dL |
These numbers show more than just temporary shifts—they reflect measurable physiological disruption across multiple systems.
Suppressed testosterone means low energy, poor libido, depression, and impaired recovery. Without proper intervention, these symptoms can persist.
Many users assume that because Turinabol is “mild,” recovery will be easy. This is a dangerous misconception.
Case studies shared on AnabolicMinds reveal individuals struggling with lethargy, insomnia, and emotional flatness for months after stopping a solo Tbol cycle.
Why?
Because any exogenous steroid use shuts down endogenous hormone production, regardless of perceived strength.
That’s where Post-Cycle Therapy (PCT) becomes non-negotiable.
Even after a solo Turinabol cycle, you need structured recovery:
Skipping PCT dramatically increases the risk of prolonged hypogonadism—a condition where your body fails to restart natural testosterone production.

One of the most underdiscussed aspects of Turinabol is its effect on heart health.
Studies and user reports consistently show:
This shift creates a pro-atherogenic environment—increasing long-term risk of arterial stiffness and cardiovascular disease.
Exercise alone cannot fully offset these lipid disruptions. In fact, intense training may amplify oxidative stress when combined with altered cholesterol profiles.

Turinabol has a relatively low androgenic rating (~50 vs. testosterone at 100), so severe androgenic sides are rare—but not absent.
Reported issues include:
Note: While Turinabol doesn’t convert to DHT, it still binds to androgen receptors, meaning genetic sensitivity matters.
If you’re prone to male pattern baldness, even mild exposure can accelerate hair loss.
Interestingly, a review in Endocrine Reviews found that topical finasteride had limited efficacy in preventing androgenic alopecia compared to oral formulations:

Turinabol does not aromatize, making it one of the few anabolics with zero estrogenic activity.
This means:
However, this also means there’s no estrogen-mediated joint lubrication or mood stabilization, which some users notice as increased joint discomfort or emotional flatness.
There’s typically no need for aromatase inhibitors (AIs) during a Tbol cycle—unlike with testosterone or Dianabol.
Turinabol is almost never used by women due to high virilization risk.
Even at micro-doses (5–10 mg/day), female users report:
Due to its strong anabolic nature and lack of safety data in women, Turinabol is considered unsuitable for female use.
Safer alternatives exist, such as Anavar (oxandrolone) or selective androgen receptor modulators (SARMs), though all carry caveats and regulatory concerns.

You can’t manage what you don’t measure.
Below is a de-identified example of blood panel results from a 32-year-old male bodybuilder before and after an 8-week Turinabol-only cycle (40 mg/day):
| Biomaker | Pre-Cycle | Post-Cycle | Change |
| ALT (liver enzyme) | 38 U/L | 165 U/L | ↑ 330% |
| AST | 32 U/L | 89 U/L | ↑ 178% |
| HDL Cholesterol | 56 mg/dL | 31 mg/dL | ↓ 45% |
| LDL Cholesterol | 94 mg/dL | 138 mg/dL | ↑ 47% |
| Triglycerides | 110 mg/dL | 185 mg/dL | ↑ 68% |
| Total Testosterone | 512 ng/dL | 198 ng/dL | ↓ 61% |
| Free Testosterone | 14.2 ng/dL | 5.1 ng/dL | ↓ 64% |
Despite reporting “feeling fine” throughout the cycle, this individual experienced dramatic shifts in markers linked to liver health, cardiovascular risk, and hormonal balance.
Choosing a compound isn’t just about results—it’s about risk tolerance.
Here’s how Turinabol compares to other popular oral and injectable options commonly used in bodybuilding:
| Compound | Liver toxicity | Estrogenic effects | Androgenic effects | Pct required | Notes |
| Turinabol | High | None | Low | Yes | Dry gains, good for cutting; hepatotoxic |
| Anavar (Oxandrolone) | Moderate | None | Very Low | Sometimes | Mild, well-tolerated, expensive |
| Winstrol (Stanozolol) | High | None | Moderate | Yes | Joint discomfort common; lowers HDL |
| Dianabol (Methandrostenolone) | Very High | High (aromatizes) | Moderate | Yes | Strong gains but high bloat and liver load |
| SARMs (e.g., Ostarine) | Low | None | Minimal | Often needed | Not FDA-approved; limited human data |
While Turinabol offers clean, dry muscle growth with minimal estrogenic or dermatological side effects, its hepatic load and lipid disruption make it far from benign.
Moreover, unlike SARMs—which are often falsely assumed to be safer—Turinabol’s mechanism of action is well-documented, meaning its risks are predictable and measurable.
Let’s confront the myths head-on using scientific insight and community-reported outcomes.
✅ Truth: It’s less hepatotoxic than Dianabol, but still causes elevated liver enzymes in many users. Blood work confirms this repeatedly.
✅ Truth: HPTA suppression is real and requires active recovery. Skipping PCT leads to extended downtime and possible hormonal dysfunction.
✅ Truth: Any oral steroid introduces significant metabolic load. Beginners should prioritize education, diet, training, and medical oversight before considering PEDs.
✅ Truth: HDL drops significantly—cardiovascular risk increases, especially in those with family history of heart disease or poor lifestyle habits.
