Dianabol — known chemically as methandrostenolone or methandienone, and almost universally as Dbol — is the oral compound that effectively created the modern performance-enhancement market. It was first described in 1955, synthesised by researchers at CIBA in Basel, Switzerland, and marketed in the United States from 1958. Nearly seventy years later it is still the reference point every other oral is measured against.
This listing is Dianabol 40 mg per tablet, 50 tablets per bottle. It is a 17α-alkylated oral, which is what allows it to survive first-pass liver metabolism and work in tablet form — and also what makes liver management non-negotiable. Every batch we stock is sent for independent HPLC analysis, and the certificate for this product is linked further down this page.
Methandrostenolone is a derivative of testosterone with a C17α methyl group and an added double bond that reduces its conversion to DHT. Reported anabolic-to-androgenic ratios sit in the range of roughly 1:1 to 1:8 in favour of anabolic activity — meaningfully more selective than testosterone, while still carrying moderate androgenic effect.
Two properties explain why it acts as fast as it does. First, it has very low affinity for SHBG — roughly 10% that of testosterone and around 2% that of DHT — so a much larger fraction of what you take circulates free and biologically active. Second, it does not need to be released from an ester, so blood levels rise within hours of the first dose rather than over the weeks a long-ester injectable needs to reach steady state. That combination is why Dianabol is traditionally used to front-load a longer testosterone cycle rather than run on its own.
Dianabol’s elimination half-life is short — around 3 to 6 hours. A single daily dose therefore produces a sharp peak and an equally sharp trough, with blood levels swinging substantially inside twenty-four hours. This is why split administration across the day is the near-universal protocol in the research literature and in practice: it flattens the curve and keeps serum levels more even.
The short half-life has a second, less discussed consequence. Because Dianabol clears quickly, people frequently assume its effects clear quickly too. They do not. Suppression of the hypothalamic-pituitary-gonadal axis, the liver enzyme response and the blood pressure response all persist well beyond the point where the compound itself is gone.
The original medical dosing for methandrostenolone was 5–10 mg per day for men and 2.5 mg per day for women. Performance-context use in the literature runs considerably higher and is almost always described as a short block rather than a continuous protocol — commonly four to six weeks maximum, run alongside an injectable testosterone base rather than alone.
Two practical points that matter more than the number itself:
This information is provided for research and educational purposes. It is not a dosing recommendation, and nothing here substitutes for qualified medical supervision.
Methandrostenolone aromatises — but not in the way most product pages describe it. Its conversion rate via aromatase is actually lower than testosterone’s. The problem is what it converts into: 17α-methylestradiol, a methylated estrogen that is resistant to normal metabolic breakdown. Less conversion, but the resulting estrogen hangs around and hits harder. That is the mechanism behind Dianabol’s reputation for water retention and gynecomastia risk.
The practical implication is that an aromatase inhibitor should be planned for from the outset rather than added reactively once symptoms appear. Arimidex (Anastrozole) and Aromasin (Exemestane) are the two standard options. Proviron is sometimes used alongside for its SHBG and free-androgen effects, though it is not a substitute for an AI.
One caution that runs the other way: crushing estrogen to the floor is its own problem. Low estradiol brings joint discomfort, flat mood, poor lipids and reduced libido — frequently misattributed to the compound itself. Control estrogen; do not eliminate it.
The C17α methyl group that makes Dianabol orally active also makes it hepatotoxic. Elevated liver enzymes with extended or high-dose use are well documented, which is precisely why the duration guidance above is short rather than open-ended.
What this means in practice: baseline and follow-up liver panels, no alcohol, no concurrent methylated orals, no over-the-counter compounds that add hepatic burden, and a defined stop date set before starting rather than decided later.
Most Dianabol pages talk about the liver and stop there. In practice, the effects people actually run into first are cardiovascular. 17α-alkylated orals suppress HDL and raise LDL aggressively — more so than most injectables at comparable anabolic effect — and the water retention discussed above pushes blood pressure up on top of that.
Headaches, a pounding pulse at rest and disproportionate breathlessness during cardio are the common early signals. Monitoring blood pressure at home during use costs almost nothing and is the single most useful thing anyone running an oral can do. Sodium control, ongoing cardiovascular work and a lipid panel before and after complete the picture.
These three oral compounds get compared constantly, and they behave very differently:
Dianabol is antigonadotropic — it suppresses natural testosterone production, and that suppression does not resolve on its own timeline. Post-cycle therapy is planned around the base compound’s clearance, not Dianabol’s, since Dbol is almost always run alongside an injectable testosterone.

This Dianabol has been analysed by Janoshik Analytical, an independent laboratory that publishes its results at a verifiable URL rather than as an image we control. The certificate of analysis for this product is public: view the HPLC report for KGEAR Dianabol 40 mg.
Independent verification matters more with orals than most buyers realise, because tablet pressing introduces variation that raw powder analysis does not capture. A report on the raw material tells you nothing about what actually ended up in the tablet. Our full report library is on the HPLC test reports page.

40 mg per tablet sits at the higher end of what is commonly available — many market products are 10, 20 or 25 mg. The advantage is flexibility: a 40 mg tablet can be split for smaller split-dose administration through the day, which suits Dianabol’s short half-life.
Because there is no ester to cleave and SHBG binding is minimal, blood levels rise within hours. Noticeable strength and fullness changes are typically reported within the first week, which is exactly why it is used to front-load slower injectable cycles.
In most cases yes. Methandrostenolone converts to 17α-methylestradiol, a metabolism-resistant estrogen, so estrogen-related effects appear readily. An AI such as Arimidex or Aromasin should be planned before starting, not added after symptoms.
Approximately 3 to 6 hours, which is why administration is conventionally split across the day rather than taken as a single dose.
Yes. It is 17α-alkylated, and hepatotoxicity with extended or high-dose use is documented. Short defined blocks, liver panels before and after, no alcohol and no concurrent methylated orals are the standard precautions.
Neither is universally better. Anadrol produces larger scale weight gain but with more appetite suppression, malaise and hepatic load. Dianabol is generally the better tolerated of the two at comparable effect.
It is not conventionally done. Dianabol suppresses natural testosterone production, so running it alone leaves the user with no androgen support once suppression sets in. It is normally paired with an injectable testosterone base.
Yes — independently, by Janoshik Analytical, with the certificate published at a verifiable third-party URL. The report is linked here and in our report library.
