Mastabol 100 by British Dragon delivers 100 mg/mL of Drostanolone Propionate, a fast-acting injectable steroid ideal for cutting cycles and contest prep. Known for its ability to harden muscles and reduce estrogenic side effects, it's often the finishing touch in a well-structured cycle. This 10 mL vial is preferred by serious athletes who want definition, density, and dry gains.
British Dragon's reputation for pharmaceutical-grade production ensures each vial of Mastabol 100 is properly dosed, sterile, and effective. The Propionate ester allows the Drostanolone to act quickly, making it a top choice during final weeks before competition or as a non-aromatizing base in lean stacks.
Originally developed for breast cancer treatment due to its anti-estrogenic properties, Drostanolone Propionate doesn't convert to estrogen and may even inhibit it. It binds strongly to androgen receptors, promoting muscle density and fat oxidation. That's why it remains a top choice for cutting cycles where a dry, sharp look is the goal.
According to research indexed in PubMed, Drostanolone demonstrated measurable anti-estrogenic properties in clinical settings, which translates into real-world benefits for athletes seeking a crisp, dry physique.
The standard dose of Mastabol 100 ranges from 300 to 500 mg/week, typically split into EOD (every other day) injections due to the short Propionate ester. A typical schedule might include Monday/Wednesday/Friday/Sunday administration to keep blood levels stable.
British Dragon's Mastabol 100 is frequently combined with other fast-acting compounds for optimal results. Ideal stacks include:
Mastabol 100 does not aromatize into estrogen, making it perfect for estrogen-sensitive individuals or those looking to eliminate bloat. In fact, it may reduce the need for additional aromatase inhibitors when stacked with moderate doses of testosterone.
Although Drostanolone is mildly suppressive, users should still run a full post-cycle therapy (PCT). Start PCT 3–5 days after your last injection:
If you're seeking lean gains and vascularity, this British Dragon Masteron Propionate injectable offers one of the best quality-to-price ratios. Domestic U.S. delivery ensures faster turnaround and avoids customs risks.
Mastabol 100 is ideal for intermediate to advanced users during the final stages of a cut. It is not recommended for bulking cycles, as it does not cause significant water retention or size increase. However, when lean muscle, hardness, and aesthetics matter most, Mastabol 100 shines.
Because of the short Propionate ester, it's best injected every other day to maintain stable blood hormone levels.
