4-Chlorodehydromethyltestosterone(CAS 2446-23-3)Strength increase API

4-Chlorodehydromethyltestosterone is an oral anabolic-androgenic steroid (AAS) that structurally represents a cross between methandrostenolone (Dianabol) and clostebol. By introducing a 4-chloro substitution, the compound is completely prevented from interacting with the aromatase enzyme, rendering it incapable of converting into estrogen.Pharmacologically, it exhibits a distinct separation of androgenic and anabolic effects, favoring a high anabolic potency with exceptionally low androgenic activity. It does not cause estrogenic side effects such as subcutaneous water retention or gynecomastia.
