Mastabol 100 by British Dragon Pharmaceuticals contains 100 mg/mL of Drostanolone Propionate in a 10 mL vial. This fast-acting DHT-derived anabolic steroid is a favorite in cutting cycles for its dry, hardening effect and anti-estrogenic properties.

What is Mastabol 100?

Drostanolone Propionate, sold under the brand name Mastabol 100, is a short-ester anabolic steroid that provides a lean, dry physique with enhanced vascularity.

  • Enhances muscle definition and hardness
  • No water retention or estrogen-related bloating
  • Improves muscle density and vascularity
  • May reduce estrogenic side effects in stacks

Dosage & Usage Guidelines

Recommended dosage is 100 mg every other day for men, typically for 6–10 weeks. It's most effective when body fat is already low, enhancing cosmetic appearance by reducing subcutaneous water.

Stacking Suggestions

Mastabol 100 is often stacked with compounds like Testabol Propionate 100 or Trenabol Acetate 100 for aggressive cutting cycles. Since Mastabol has no aromatization, it's ideal for estrogen-sensitive users seeking dry gains.

Post-Cycle Therapy (PCT)

Mastabol 100 will suppress natural testosterone. Begin PCT with Clomiphene 3–5 days after your last injection to support recovery and hormonal normalization.

Side Effects and Warnings

Common side effects include oily skin, increased aggression, and potential hair loss in genetically prone individuals. Women should avoid due to strong virilizing effects. Not suitable for users with prostate issues.
