Key Features
- Mesterolone Core: Steroidal derivative of dihydrotestosterone with strong androgenic properties.

| Professional Taper / Final Prep | 150 mg daily | Maximum of 3 months to avoid excessive androgenic effects |
| Athletes on Estrogen‑Producing AAS (e.g., testosterone, metandienone) | 50–100 mg daily alongside aromatizing agents | Aligned with the overall steroid cycle |
