💉 Drostanolone Propionate 100mg/ml (Masteron)

Brand: Dr.X Labs
Volume: 10ml Multi-dose Vial
Administration: Intramuscular (IM) Use Only

🧬 What is Masteron?

Masteron is a DHT-derived anabolic steroid developed in the 1950s, clinically used to treat breast cancer and later adopted by athletes for its exceptional hardening and definition effects. It’s a non-aromatizing steroid known for delivering a dry, lean look without estrogenic side effects.

💪 Key Benefits

  • Enhances muscle hardness and vascularity
  • Reduces subcutaneous water for a dry appearance
  • Preserves lean mass during cutting cycles
  • May suppress estrogenic effects of other compounds
  • Excellent for contest prep and final weeks of dieting

⚠️ Side Effects

  • Androgenic issues: acne, oily skin, hair loss (DHT-related)
  • Suppresses natural testosterone—test base recommended
  • May negatively impact cholesterol (lowers HDL)

📌 Advice & Precautions

Masteron should be paired with a testosterone ester for hormonal stability. Though mild, it still suppresses the HPTA. Frequent dosing (EOD) is necessary due to its short ester. Bloodwork and cholesterol monitoring are recommended.
