4-Chlorohydromethyltestosterone
is a performance-enhancing steroid used to increase muscle mass. It is not
FDA-approved and is used outside medical applications in bodybuilding and sports.
Modern applications focus on improving muscle strength and endurance.
Substitution therapy (SGT) is not required, as it does not affect natural
hormonal levels. It was developed in the 1980s and is especially popular among
athletes.
