MASTERON 100

MASTERON 100

Description

MASTERON 100 (Drostanolone Propionate) is a synthetic derivative of dihydrotestosterone (DHT), primarily utilized for its antineoplastic properties in the clinical management of certain hormone-sensitive cancers, particularly in female patients with advanced-stage breast carcinoma. This injectable formulation delivers 100mg of drostanolone propionate per milliliter, suspended in a sterile oil-based vehicle with excipients suitable for intramuscular administration.

Metabolic Interactions

Drostanolone propionate functions as a prodrug of drostanolone, which exerts its effects by binding to intracellular androgen receptors. Its mechanism of action includes stimulation of protein synthesis, positive nitrogen balance, and potassium retention, contributing to its pronounced anabolic activity. Unlike many other anabolic steroids, drostanolone demonstrates strong anti-estrogenic activity by inhibiting estrogen and prolactin receptors, which underpins its therapeutic role in estrogen-dependent tumors. Importantly, it lacks progestogenic properties, reducing the risk of associated hormonal side effects.

Dosage

The standard therapeutic and performance-enhancing regimen involves intramuscular administration of 100mg once weekly, although frequency may vary based on individual goals and medical supervision.

Drug Interactions

Currently, no well-documented pharmacological interactions have been established with MASTERON 100. Nonetheless, users should always consult a healthcare provider prior to concurrent use with other hormonal or cytotoxic agents.

Side Effects

Potential adverse effects associated with drostanolone use include:
  • Acneiform eruptions   
  • Signs of virilization (particularly in female users)   
  • Cephalalgia (headaches)   
  • Fluid retention   
  • Hypercalcemia in rare instances
