LGD-4033 and Tamoxifen Interaction

Avoid
Mechanism-based 64% confidence

LGD-4033 and Tamoxifen have a potentially harmful interaction with 64% confidence. Both LGD-4033 and Tamoxifen 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, so monitoring these systems is recommended.

Compound Profiles

LGD-4033

Selective Androgen Receptor Modulator | Lean Mass

LGD-4033 binds to the androgen receptor with high affinity (Ki of approximately 1 nM), functioning as a potent and selective agonist in muscle and bone tissue. Like other SARMs, its tissue selectivity is mediated by differential cofactor recruitment: upon binding to the AR, LGD-4033 induces a receptor conformation that preferentially recruits coactivators expressed in skeletal muscle and bone, while showing minimal agonist activity in androgen-sensitive tissues such as the prostate and skin.

Tamoxifen

Selective Estrogen Receptor Modulator | PCT & Breast Cancer Treatment

Tamoxifen competitively binds to estrogen receptors (primarily ERalpha) and exerts tissue-selective effects depending on the local coactivator and corepressor environment. In breast tissue and the hypothalamus, tamoxifen acts as an estrogen antagonist, blocking estradiol-mediated signaling.
