Testosterone Decanoate 250
Active Ingredient
Testosterone Decanoate
- Esterified form of testosterone designed for prolonged release after intramuscular administration.
- Chemical formula: C29H46O3.
- Molecular weight: approximately 442.7 g/mol.
- Appears as a white to off-white crystalline powder in raw form.
Concentration & Formulation
- Typically supplied as 250 mg/ml in an oil-based injectable solution.
- The long-chain decanoate ester increases lipophilicity, enabling a slow-release depot effect when injected intramuscularly.
Pharmacological Profile
- Functions as a prodrug of testosterone; the ester is hydrolyzed in the body to yield active testosterone.
- Exhibits androgenic and anabolic activity consistent with endogenous testosterone.
- Produces an extended duration of action, allowing longer intervals between injections compared to short-acting esters.
Mechanism of Action
- After hydrolysis, free testosterone binds to androgen receptors in target tissues.
- Supports development and maintenance of male secondary sexual characteristics, muscle mass, bone density, and normal androgen-dependent functions.
Therapeutic Use
- Used in testosterone replacement therapy for males with clinically confirmed testosterone deficiency (hypogonadism).
- May be used in other medically supervised androgen-replacement contexts where long-acting testosterone is indicated.
Physical & Chemical Characteristics
- Practically insoluble in water; soluble in oils and organic solvents, allowing formulation as an injectable solution.
- The decanoate ester prolongs release and absorption, leading to stable serum testosterone levels over extended periods.
Key Attributes of Testosterone Decanoate 250
