Mastabol 100

Mastabol 100 is a common brand name for Drostanolone Propionate, widely distributed by the underground laboratory British Dragon . Below is the descriptive breakdown of this specific product.

1. Product Identity

• Brand Name: Mastabol 100
• Active Ingredient: Drostanolone Propionate
• Concentration: 100 mg/mL100 mg/mL
• Form: Injectable solution (oil-based)
• Primary Use: Bodybuilding, specifically during "cutting" or pre-contest phases for muscle hardening.

2. Pharmacological Properties

Mastabol 100 utilizes the Propionate ester, which dictates how the hormone behaves once it enters the body.

• Ester: Propionate (short-chain fatty acid).
• Half-life: Approximately 2−32−3 days.
• Action: Provides a rapid onset of release. Because the hormone is cleared from the system relatively quickly, frequent administration is required to prevent "troughs" or dips in blood hormone levels.
• Non-Aromatizing: The compound does not convert to estrogen. In fact, it is often noted for having mild anti-estrogenic effects, which helps reduce the water retention typically associated with other anabolic steroids.

3. Common Administration Patterns

Due to the short half-life of the Propionate ester, users typically follow specific protocols to maintain stable blood plasma levels:

• Injection Frequency: Most users administer injections every other day (EOD) or at least 3 times per week.
• Standard Dosage: While individual requirements vary, a common range often cited in non-medical circles is 300 mg300 mg to 500 mg500 mg per week.

4. Important Considerations for Mastabol (British Dragon)

It is critical to note that "British Dragon" as an original company ceased operations years ago.

• Market Authenticity: Almost all products currently labeled "British Dragon" or "Mastabol" are produced by various independent labs using the original branding. There is no central quality control or standardized manufacturing process.
• Risk of Impurity: Because these are UGL (Underground Laboratory) products, they carry inherent risks, including:
• Contamination: Potential for lack of sterile manufacturing, leading to site infections or abscesses.
• Dosing Variance: The actual concentration may be lower than the claimed 100 mg/mL100 mg/mL, or the product may contain filler oils or different hormones entirely.
• Post-Injection Pain (PIP): High concentrations of solvents used to keep the hormone in solution can cause significant irritation at the injection site.

5. Health Risks

• Lipid Profile: Like most DHT derivatives, Mastabol can significantly lower HDL (good cholesterol) and increase LDL (bad cholesterol), stressing the cardiovascular system.
• Endocrine Suppression: Use of the compound will lead to the suppression of the hypothalamic-pituitary-gonadal (HPG) axis, resulting in the cessation of natural testosterone production.
• Androgenic Side Effects: Users may experience acne, hair loss (if genetically predisposed), and prostate enlargement.
