Mastabol 100 mg Detailed

Mastabol 100 – Drostanolone Propionate by British Dragon

Mastabol 100 by British Dragon is a fast-acting ester of Drostanolone, widely known under its pharmaceutical name, Masteron Propionate. Originally developed to treat breast cancer, its anti-estrogenic effects and muscle-hardening capabilities quickly earned it favor in bodybuilding circles.

Main Benefits and Effects

This compound excels during cutting cycles. Mastabol 100 offers significant improvements in muscle definition, density, and vascularity—without the water retention associated with aromatizing steroids. Its DHT-based structure ensures it doesn't convert to estrogen, making it ideal for users prone to gynecomastia or bloating.

Due to its anti-estrogenic nature, it's also commonly used alongside compounds such as Aquabol Suspension to keep estrogen levels balanced while preserving lean mass. In some cases, it's used as a mild AI alternative during cycles involving aromatizing steroids.

Cycle Recommendations

Typical doses range from 300–700 mg per week, often split into EOD injections due to its short ester. Advanced users may run Mastabol 100 for 8–10 weeks, frequently stacking it with Trenabol Acetate or Oxanabol to maximize body recomposition effects. Solo cycles are also popular among those seeking clean, dry gains.

Its synergy with non-aromatizing agents like Primobol Inject makes Mastabol especially valuable in pre-contest preparation, giving physiques a sharp, sculpted appearance without risk of water retention.

Side Effects and Safety

Although Drostanolone Propionate is considered mild, androgenic side effects are possible—especially in genetically sensitive users. These may include acne, hair thinning, or aggression. Importantly, due to its DHT derivation, Mastabol 100 should be avoided by those with pre-existing prostate issues.

It's not liver toxic and doesn't impact cholesterol levels as harshly as some orals. However, natural testosterone suppression still occurs. A proper post-cycle therapy (PCT) protocol using agents like Tamoxifen or Clomid is essential.

Scientific Backing

Drostanolone is listed in various peer-reviewed studies for its efficacy in androgenic therapy and cancer treatment. For reference, review the Wikipedia article on Drostanolone Propionate for historical and medical insights.

Frequently Asked Questions

What is the use of drostanolone metabolite?

Drostanolone metabolites serve as biomarkers in drug testing. They reflect the parent compound's activity and are often screened in anti-doping panels.

Is Mastabol 100 good for fat loss?

Yes. Mastabol 100 promotes fat loss indirectly through its androgenic effects and enhanced muscle hardness, particularly when combined with a calorie-controlled diet.

Does Mastabol 100 affect estrogen levels?

No. Drostanolone does not aromatize to estrogen, and in fact, it may act as a mild aromatase inhibitor, helping to reduce estrogenic side effects during cycles.

Can women use Mastabol 100?

Due to its strong androgenic nature, Mastabol 100 is generally not recommended for women, as it may cause virilization symptoms such as deepened voice or facial hair.

How fast does Mastabol 100 act in the body?

As a propionate ester, it begins acting within 24–48 hours after injection. This fast onset makes it ideal for shorter cutting phases or competition prep.
