Clascoterone and Testosterone Interaction

Monitor
Mechanism-based 60% confidence

Clascoterone and Testosterone have an interaction requiring monitoring for interaction with 60% confidence. Both Clascoterone and Testosterone carry androgenic activity. Additive androgenic load increases risk of acne, hair loss, and prostate effects. Monitor for dose-dependent side effects. These compounds primarily affect different organ systems.

Compound Profiles

Clascoterone

Topical Androgen Receptor Inhibitor | Acne & Hair Loss

Clascoterone acts as a competitive antagonist of the androgen receptor (AR). When applied topically, it penetrates the skin and binds directly to androgen receptors in target tissues -- sebaceous glands (for acne) and dermal papilla cells of hair follicles (for alopecia).

Half-life: Short topical (local action; rapidly metabolized to cortexolone) Typical dose: Acne: 1% cream 2x/day | Hair loss: 7.5% solution once daily hair loss, skin

Testosterone

Anabolic-Androgenic Steroid | Primary Male Sex Hormone

Testosterone exerts its effects primarily through binding to the intracellular androgen receptor (AR), forming a hormone-receptor complex that translocates to the nucleus and modulates gene transcription. This drives protein synthesis in skeletal muscle (anabolic effect), stimulates erythropoietin production in the kidneys to increase red blood cell mass, promotes osteoblast activity and bone mineral density, and regulates libido and cognitive function.

Half-life: ~8 days (cypionate) Typical dose: 100-200 mg/week (TRT) anabolic, sexual health, metabolic
