Veboldex 400 (Boldenone Undecylenate) is a derivative of testosterone, which exhibits strong anabolic and moderately androgenic properties. The undecylenate ester greatly extends the activity of the drug (the undecylenate ester is only one carbon atom longer than decanoate), so that clinically injections would need to be repeated every two or three weeks. Boldenone exhibits a pronounced effect on lean body weight, appetite and general disposition. This compound is also said to show a marked ability for increasing red blood cell production.
Boldenone Undecylenate is not a rapid mass builder, instead Boldenone is looked at to provide a slow but steady gain of strength and quality muscle mass. The most positive effects are seen when it is used for longer periods, usually lasting more than 8-12 weeks in duration. The muscle gained should not be the smooth bulk seen with some androgens, but very defined and solid. Since water is not contributing greatly to the diameter of the muscle, much of the size gained can be retained after use has been discontinued. Although it stays active for a much longer time, Boldenone is often injected at least once per week. Tylpical in the range of 200-400mg per week for men, 50-75 mg per week for women.
