LGD-4033 and Rapamycin Interaction

Monitor
Mechanism-based 47% confidence

LGD-4033 and Rapamycin have an interaction requiring monitoring for interaction with 47% confidence. Both LGD-4033 and Rapamycin negatively affect lipid profiles. Combined use may significantly worsen HDL/LDL ratios. Include lipid support and get bloodwork mid-cycle. These compounds primarily affect different organ systems.

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.

Rapamycin

mTOR Inhibitor | Longevity & Immunosuppression

Rapamycin exerts its effects by binding to the intracellular protein FKBP12, forming a complex that directly and specifically inhibits mechanistic target of rapamycin complex 1 (mTORC1). mTORC1 is a master nutrient-sensing kinase that integrates signals from growth factors, amino acids, energy status, and stress to regulate cell growth, proliferation, and metabolism.
