Anadrol vs Proviron

FDA Approved vs Well Studied
avoid Mechanism-based · 64% Both Anadrol 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

Anadrol Proviron
Weight 332.48 Da 304.47 Da
Half-life ~8-9 hours ~12 hours
Type 17-alpha alkylated anabolic steroid (C21H32O3) DHT derivative (C20H32O2)

Key Benefits

Anadrol
01 Rapid and dramatic increases in muscle mass and bodyweight
02 Exceptional strength gains, often noticeable within the first week
03 Potent stimulation of erythropoietin and red blood cell production
04 Increased appetite and nutrient partitioning in some users
05 Improved recovery between training sessions
06 Full, round muscle appearance due to intramuscular water and glycogen retention
07 FDA-approved treatment for various forms of anemia
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

Anadrol
Significant water retention and bloating (estrogenic, not aromatase-mediated)
Elevated blood pressure (fluid volume and RBC increase)
Severe liver stress and elevated liver enzymes (AST/ALT)
Back pumps and lower back pain during exercise
Headaches (often blood pressure-related)
Appetite suppression (paradoxical for a mass-building compound)
Lethargy and fatigue (hepatic strain-related)
Acne and oily skin
Suppression of natural testosterone production
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 significantly elevated liver enzymes
Prostate cancer or breast cancer in males
Nephrotic phase of nephritis
Hypercalcemia (Anadrol can exacerbate calcium levels)
Pregnancy (Category X - causes virilization of the female fetus)
Known hypersensitivity to oxymetholone
Concurrent use of other 17-alpha alkylated oral steroids (compounded liver toxicity)
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)
