Durabol 100 by British Dragon

Effective substance: nandrolone phenylpropionate
Content: 100mg/ml
Vial: 10ml
Form: fluid in inject form

 Durabol is a fast-acting form of nandrolone. Nandrolone is chemically related to the male hormone testosterone. Compared to testosterone, it has an enhanced anabolic and a reduced androgenic activity. This has been demonstrated in animal bioassays and explained by receptor binding studies. The low androgenicity of nandrolone is confirmed in clinical use. In the human, nandrolone has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis. In women with disseminated mammary carcinoma, nandrolone has been reported to produce objective regressions for many months. Furthermore, nandrolone has a nitrogen-saving action. This effect on protein metabolism has been established by metabolic studies and is utilised therapeutically in conditions where a protein deficiency exists such as during chronic debilitating diseases and after major surgery and severe trauma.

Nandrolone Phenylpropionate (Durabol) is a highly effective anabolic steroid characterized by its rapid onset of action and favorable ratio of tissue-building properties to androgenic side effects.

Detailed below is the proper description and clinical profile of the compound:

Clinical Mechanism

• Anabolic Superiority: Durabol is engineered to maximize muscle and bone tissue synthesis while minimizing male-pattern side effects. Research indicates it binds strongly to the androgen receptor but does not break down into the more potent dihydrotestosterone (DHT) in the same way testosterone does.
• Nitrogen Retention: It facilitates a "nitrogen-saving" state. Since nitrogen is a primary component of amino acids, this prevents muscle wasting and promotes repair in patients suffering from trauma or severe surgery.
• Bone Density: It positively influences calcium metabolism, making it a viable therapeutic option for increasing bone mass in patients with osteoporosis.

Therapeutic Applications

• Oncology: Used in the treatment of disseminated mammary carcinoma (breast cancer) in women, where it has been shown to produce objective regressions.
• Recovery: Prescribed for chronic debilitating diseases to reverse protein deficiency and weight loss.
• Anemia: Stimulates erythropoietin production, leading to an increase in red blood cell count.

Pharmacokinetics

• Fast-Acting Ester: Unlike the slower Decanoate version, the Phenylpropionate ester allows for a quick rise in blood concentration levels.
• Half-Life: Approximately 2.5 to 3 days, requiring more frequent administration to maintain therapeutic levels.

 Side Effects & Precautions

1. Hormonal Balance: While androgenicity is reduced, it can still suppress natural hormone production and may cause virilization (masculinization) in women if doses are not strictly managed.
2. Fluid Balance: Potential for mild water retention and impact on blood pressure.
3. Metabolic Impact: May affect cholesterol levels (lowering HDL) and requires monitoring of liver function during long-term use.

Administration

Durabol is administered via deep intramuscular injection. Because of its fast-acting nature, clinical or performance dosing is typically split into multiple applications per week to ensure stable plasma concentrations.
