Mechanism of action

ASC-01 binds to the androgen receptor with high selectivity, promoting anabolic effects in muscle and bone while minimizing androgenic side effects in other tissues. This tissue-selective activation aims to provide the therapeutic benefits of androgens without the adverse effects associated with traditional androgen replacement therapy or non-selective androgens.
