Product Introduction

An androgenic drug with anti-androgenic and weak anabolic activity. An oral formulation (drostanolone tablets) is used for benign prostatic hyperplasia and androgenic alopecia; the entries here are compounded oil-based ester injectables.

Therapeutic Use

Benign prostatic hyperplasia, male-pattern androgenic alopecia, acne; use in women requires great caution. The injectable ester forms have no approved indication in most markets

Mode of Action

5α-reductase-inhibitor-like structure with dual antagonist/partial-agonist activity at the androgen receptor; anti-androgenic effect dominates the anabolic one; not significantly aromatised; preferential action in DHT-target tissues

Administration & Monitoring

Use as prescribed; with long-term use monitor PSA, lipids, liver function, and menstrual/endocrine changes in women

Important Safety Information

Prescription medicine; non-medical abuse is unlawful. Combining with other anabolic steroids may aggravate androgenic adverse effects

Adverse Reactions

Injection-site reactions; headache, flushing; raised PSA and prostatic irritation in men; menstrual disturbance, hirsutism and voice change in women; mild transaminase elevation and lipid changes with long-term use

Important Risks

Fluctuating testosterone levels if doses are missed; low but non-zero gynaecomastia risk; adverse lipid profile

Contraindications

Hypersensitivity; pregnancy and lactation; known or suspected prostate or breast cancer; urinary obstruction in men; paediatric use

Special Populations

Usage Limitations
