Anastrozole and RAD-140 Interaction

Avoid
Mechanism-based 53% confidence

Anastrozole and RAD-140 have a potentially harmful interaction with 53% confidence. Both Anastrozole and RAD-140 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 liver and heart, so monitoring these systems is recommended.

Compound Profiles

Anastrozole

Aromatase Inhibitor | Estrogen Management

Anastrozole competitively binds to the heme group of the aromatase enzyme (cytochrome P450 19A1), reversibly inhibiting its catalytic activity. Aromatase is responsible for the final step in estrogen biosynthesis, converting testosterone to estradiol and androstenedione to estrone in peripheral tissues including adipose, muscle, liver, and brain.

RAD-140

Selective Androgen Receptor Modulator | Investigational SARM

RAD-140 binds to the androgen receptor (AR) with high affinity and selectivity, functioning as a full agonist in muscle and bone tissue while exhibiting minimal agonist activity in the prostate and other androgen-sensitive tissues. This tissue selectivity is achieved through differential cofactor recruitment: upon binding to the AR, RAD-140 induces a conformational change that favors interaction with coactivators predominantly expressed in skeletal muscle and bone, rather than those prevalent in prostate or sebaceous glands.

Shared Safety Flags

2x 2 androgenic compounds (Anastrozole, RAD-140). Additive androgenic load — increased risk of hair loss, acne, prostate effects.
2x 2 hepatotoxic compounds (Anastrozole, RAD-140). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 HPTA-suppressive compounds (Anastrozole, RAD-140). Deep hormonal shutdown expected — plan extended PCT.
2x 2 compounds disrupt lipids (Anastrozole, RAD-140). Get lipid panel mid-cycle — consider adding lipid support.
