Nandrolone and Oxandrolone Interaction

Avoid
Mechanism-based 64% confidence

Nandrolone and Oxandrolone have a potentially harmful interaction with 64% confidence. Both Nandrolone and Oxandrolone carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. Both compounds affect the gonads and heart and liver and blood vessels, so monitoring these systems is recommended.

Compound Profiles

Nandrolone

Anabolic-Androgenic Steroid | Joint & Collagen Support

Nandrolone binds to the androgen receptor (AR) with affinity comparable to testosterone, promoting nitrogen retention, protein synthesis, and satellite cell activation in skeletal muscle tissue. Its anabolic effects are mediated through AR-dependent gene transcription that upregulates muscle-specific proteins including myosin heavy chain and IGF-1.

Half-life: ~6-12 days (decanoate) Typical dose: 100-200 mg/week (therapeutic) anabolic, healing, sexual health

Oxandrolone

Oral Anabolic Steroid | Lean Mass & Recovery

Oxandrolone exerts its anabolic effects primarily through binding to the intracellular androgen receptor (AR), promoting nitrogen retention and protein synthesis in skeletal muscle tissue. As a DHT derivative, it cannot be converted to estrogen by the aromatase enzyme, which means it does not cause estrogen-mediated water retention or gynecomastia.

Half-life: ~9-10 hours Typical dose: 20-50 mg/day (male), 5-20 mg/day (female) anabolic, healing

Shared Safety Flags

2x 2 androgenic compounds (Nandrolone, Oxandrolone). Additive androgenic load — increased risk of hair loss, acne, prostate effects.
2x 2 compounds share the carcinogenic-risk safety flag (Nandrolone, Oxandrolone). Monitor accordingly.
2x 2 hepatotoxic compounds (Nandrolone, Oxandrolone). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 HPTA-suppressive compounds (Nandrolone, Oxandrolone). Deep hormonal shutdown expected — plan extended PCT.
2x 2 compounds disrupt lipids (Nandrolone, Oxandrolone). Get lipid panel mid-cycle — consider adding lipid support.
2x 2 compounds share the teratogenic safety flag (Nandrolone, Oxandrolone). Monitor accordingly.
