Product Description
4-Chlorotestosterone Acetate, also known as Clostebol Acetate, is a synthetic anabolic steroid derived from testosterone. It is chemically modified with a chlorine atom at the 4th carbon and an acetate ester, improving stability and half-life for in vitro and in vivo research.
This compound is widely studied for its anabolic-to-androgenic ratio, receptor binding affinity, and tissue selectivity in muscle hypertrophy models. It is commonly used in endocrine and pharmacological research to evaluate steroidal interactions and metabolic pathways.
