Manufacturer: British Dragon Pharmaceuticals
Pharmaceutical name: Drostanolone Propionate
Pack: 10 ml vial (100 mg/ml)
Mastabol 100 from British Dragon delivers precision-formulated Drostanolone Propionate at 100mg/ml - the gold standard for achieving razor-sharp definition, hardened muscles, and minimal water retention. This DHT-derived compound is built for serious athletes cutting for competition, prepping for photoshoots, or just wanting that dense, dry, aesthetic look that screams dedication.
Designed to amplify cutting cycles without compromising strength or lean mass, Mastabol 100 excels when calories are low and your body needs that extra edge. With its anti-estrogenic properties and fast-acting nature, it's a favorite among competitive bodybuilders and performance athletes alike.
For optimal results, users typically run Mastabol 100 at 300-500mg per week, split into 100mg EOD injections due to its short ester. It's best paired with a testosterone base like Testabol Enanthate for hormonal balance and added strength during the cycle. Many experienced lifters add Winstrol or Tren to take muscle hardness and vascularity to another level.
Cycle lengths usually range from 6 to 10 weeks depending on goals. For advanced physique refinement, Mastabol 100 is often included during the final phase of a prep or recomp when every detail matters. A highly effective 8-week stack could include:
While traditionally used for cutting, some athletes incorporate Mastabol 100 at lower doses alongside Hexyl 450 or other long-ester blends for lean recomp or even TRT supplementation. Its mild profile, strong DHT action, and non-aromatizing nature make it suitable for maintaining libido, mood, and motivation while keeping estrogen low and physique tight.
Mastabol 100 is tailor-made for:
Despite its mild suppression, post-cycle therapy is still advised. Standard PCT protocol includes:
Adding support supplements like zinc, ashwagandha, or natural test boosters may also help ease recovery and support mood post-cycle.
Being DHT-based, Mastabol 100 does not aromatize, so gynecomastia and water retention are almost nonexistent. That said, users sensitive to DHT should monitor for possible effects like oily skin or hair shedding. It's also important to note that while liver toxicity is not a concern, androgenic side effects may intensify if stacking with other strong compounds.

Mastabol 100 is mainly used in cutting cycles to enhance muscle definition, reduce estrogen-related water retention, and preserve lean mass.
Because it's fast-acting, users often notice harder muscles and improved vascularity within the first 2-3 weeks.
Not really. It's better suited for cutting or lean recomp phases due to its drying and hardening effects. For bulking, Test E or Deca would be better fits.
Great stacks include Winstrol, Tren Ace, and Testosterone Propionate. These combos enhance cutting, muscle density, and hormonal stability.
Yes. British Dragon is one of the most reputable underground labs, known for consistent product quality and verified dosing.
