Propan (Testosterone Propionate BP 100mg) is a fast-acting testosterone ester designed to boost natural testosterone levels quickly and effectively. Known for its rapid absorption and short half-life, Propan is a popular choice among bodybuilders, athletes, and fitness enthusiasts who seek fast strength gains, lean muscle mass, and fat loss without excessive water retention. Because of its short duration, it allows for better control over hormone levels and is often used in cutting cycles or to kick-start a longer cycle.
