🧪 Wissenschaftlicher Überblick

Nandrolone Decanoate (“Nandro D”) is a long-acting ester of nandrolone, a classical 19-nor anabolic-androgenic steroid.
It is used extensively as a reference compound in studies related to muscle hypertrophy, nitrogen retention, bone metabolism, connective-tissue repair, and HPG-axis suppression.
Because of its pharmacological profile and long detection time, it is also a major target in doping-control research.

The decanoate ester forms a depot in muscle tissue, releasing nandrolone gradually over many days, resulting in a long elimination half-life and sustained androgenic activity.

🧬 Wirkmechanismus

Androgen Receptor Activation
Nandrolone binds to androgen receptors in muscle, bone, and connective tissue, activating gene transcription pathways responsible for protein synthesis, growth, and structural adaptation.

Reduced 5-α-Reduction
Unlike testosterone, nandrolone converts into a weaker androgen (dihydronandrolone) in certain tissues, contributing to a lower androgenic impact in skin, scalp, and prostate models.

Nitrogen Retention & Protein Metabolism
Nandrolone improves nitrogen balance and supports protein synthesis, especially under catabolic stress—key reasons it is used in research on wasting conditions and recovery.

Erythropoiesis
Nandrolone may stimulate red blood cell production, making it relevant in anemia models and hematological studies.

Endocrine Feedback Suppression
Exogenous nandrolone suppresses LH/FSH secretion, a central topic in reproductive endocrinology research.

📚 Mögliche Forschungsanwendungen

• Lean muscle mass, hypertrophy, and recovery models
• Studies of bone density, collagen production, and tissue repair
• Investigation of catabolic vs. anabolic metabolic states
• Glucocorticoid-induced muscle and bone loss models
• Chronic disease, burn injury, and trauma recovery research
• HPG-axis suppression and endocrine disruption mapping
• Anti-doping assay development for nandrolone metabolites

All uses above apply strictly to controlled laboratory research models — not human use.

⚠️ Side Effects & Safety Considerations (Research Literature)

• Endocrine: suppression of testosterone, testicular atrophy, infertility, menstrual disruption
• Cardiovascular: adverse lipid shifts, hypertension, fluid retention
• Hepatic: potential liver enzyme elevation despite being non-17α-alkylated
• Androgenic: acne, body hair growth, voice deepening, clitoral enlargement in females
• Neuropsychiatric: mood swings, irritability, dependence-like patterns
• Other: injection-site irritation, increased hematocrit, altered glucose tolerance

These findings come from clinical literature on nandrolone and related AAS and must not be interpreted as guidance for human use.
