Mastabol 200 is a long-acting injectable anabolic steroid produced by British Dragon, featuring Drostanolone Enanthate as its active compound. Known in the bodybuilding world as "long-ester Masteron," it provides a steady release ideal for longer cutting or recomposition cycles. Unlike the short-ester Mastabol 100, this version offers convenience with fewer injections while maintaining powerful results.
British Dragon Mastabol 200 delivers a clean, dry, and aesthetic physique, enhancing muscle hardness, density, and vascularity. It does not convert to estrogen, eliminating the risk of water retention, gynecomastia, or bloating—making it ideal for bodybuilders preparing for competitions or photoshoots.
Its androgenic activity contributes to better strength gains and fat-burning effects. Furthermore, studies indicate Drostanolone Enanthate can act as a mild aromatase inhibitor, offering auxiliary estrogen control when stacked with aromatizing compounds like testosterone.
For optimal results, Mastabol 200 is typically dosed at 400–600 mg weekly, split into 2 weekly injections. The compound performs exceptionally well in cutting or recomp phases, especially when combined with agents such as Trenabol or Oxydrol. Athletes aiming for lean gains may pair it with Testabol Depot.
The cycle duration usually spans 10–12 weeks. Because it suppresses natural testosterone production, post-cycle therapy (PCT) is strongly advised. Agents like Tamoxifen or Clomid should be initiated after the ester clears the system, typically 2 weeks post-cycle.
Mastabol 200 is ideal for intermediate to advanced users focused on muscle definition, strength, and fat reduction. It is not recommended for female athletes due to its high androgenic potential. Its steady blood concentration makes it ideal for those who dislike the frequent pinning of shorter esters.
Common side effects include increased aggression, oily skin, or hair thinning—mostly in genetically predisposed users. However, it does not elevate estrogenic side effects or liver strain. Keeping doses within clinical norms minimizes risk. If acne occurs, topical treatments or Accutane (Isotretinoin) may help manage symptoms.
Drostanolone metabolites are used in drug testing to confirm steroid usage. They also indicate how the body processes and excretes the compound.
Due to its enanthate ester, Mastabol 200 stays active for around 7–9 days, allowing for less frequent injections compared to propionate-based versions.
While not primarily used for bulking, Mastabol 200 can aid in lean mass retention and fat loss during a lean bulk or recomp cycle when stacked correctly.
No. Due to its high androgenic strength, Mastabol 200 is not advised for female use and may cause virilization symptoms even at low doses.
Yes, PCT is necessary. Like all anabolic steroids, Mastabol 200 suppresses natural testosterone. Tamoxifen or Clomid should be used post-cycle.
