Dianabol vs Proviron
Well Studied vs Well Studied
avoid Mechanism-based · 64% Both Dianabol and Proviron carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.
Molecular Data
Dianabol Proviron
Weight 300.44 Da 304.47 Da
Half-life ~4-6 hours ~12 hours
Type 17-alpha-alkylated anabolic steroid (C20H28O2) DHT derivative (C20H32O2)
Key Benefits
Dianabol
01 Rapid and dramatic increases in muscle mass and bodyweight
02 Significant strength gains within the first 1-2 weeks
03 Enhanced nitrogen retention and protein synthesis
04 Improved glycogenolysis and muscular endurance
05 Pronounced muscle fullness and pumps from increased intracellular water and glycogen
06 Effective oral kickstart while waiting for injectable compounds to saturate
07 One of the fastest-acting anabolic compounds available
Proviron
01 Strong SHBG binding frees more circulating testosterone, enhancing TRT efficacy
02 Improved mood, motivation, confidence, and overall sense of well-being
03 Significant enhancement of libido and sexual function
04 Anti-estrogenic effect reduces the need for dedicated aromatase inhibitors
05 Harder, drier, more defined physical appearance without water retention
06 Minimal hepatotoxicity due to absence of 17-alpha alkylation
07 May improve sperm quality at low doses in subfertile men
08 Rapid onset of subjective well-being effects (often within days)
Side Effects
Dianabol
Significant water retention and bloating (estrogen-mediated)
Elevated blood pressure from fluid retention and increased red blood cell mass
Liver stress with elevated ALT/AST enzymes (dose and duration dependent)
Back pumps (painful lower back cramping during exercise)
Increased appetite
Oily skin and acne
Suppression of endogenous testosterone production (HPTA suppression)
Mild mood changes (increased aggression, irritability, or euphoria)
Proviron
Accelerated hair thinning or loss in those predisposed to male pattern baldness (DHT-mediated)
Mild suppression of endogenous testosterone at higher doses (though less suppressive than most AAS)
Oily skin and increased sebum production
Mild HDL cholesterol suppression with extended use
Increased body hair growth
Contraindications
Pre-existing liver disease or impaired hepatic function
Active or history of hormone-sensitive cancers (prostate, breast)
Uncontrolled hypertension or significant cardiovascular disease
Elevated hematocrit (above 54%) at baseline
Concurrent use of other hepatotoxic oral steroids (do not stack C17-aa orals)
Pregnancy or potential exposure to pregnant women
Heavy alcohol use (compounded hepatotoxicity risk)
Cholestatic liver conditions or history of drug-induced liver injury
Prostate cancer (active or history of androgen-sensitive prostate cancer)
Severe liver impairment (though hepatotoxicity risk is minimal)
Breast cancer in males
Hypersensitivity to mesterolone or any excipients
Women who are pregnant or may become pregnant (androgenic effects on fetus)
