Street information

Testosterone undecanoate remains effective in the system for only a few hours and has a particularly short half-life. Many users feel it promotes rapid strength and weight gains. It has a reputation for minimal LH and FSH suppression together with little aromatization. It is considered to virilize easily, making it unpopular with female steroid users.
