Liothyronine (T3) and Nandrolone Interaction

Avoid
Mechanism-based 70% confidence

Liothyronine (T3) and Nandrolone have a potentially harmful interaction with 70% confidence. Both Liothyronine (T3) and Nandrolone carry cardiovascular risk. Combined cardiotoxic load increases risk of cardiac events. Regular cardiac monitoring recommended. These compounds primarily affect different organ systems.

Compound Profiles

Liothyronine (T3)

Thyroid Hormone | Metabolic Optimization

Liothyronine enters target cells via monocarboxylate transporter 8 (MCT8) and other thyroid hormone transporters, then binds to nuclear thyroid hormone receptors (primarily TR-beta in metabolic tissues and TR-alpha in cardiac tissue). The T3-receptor complex forms heterodimers with retinoid X receptors (RXR) and binds to thyroid hormone response elements (TREs) on DNA, directly modulating gene transcription.

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
