Boldenone has a very long half life and can remain in the body for months or even years. The oily emulsion has an affinity for fatty tissues and resides in the body for months. The metabolites of boldenone have been found in urine 12 months after the last injection. So one has to have a plan before shooting this drug. If you are going to enter a competition in the next few months, boldenone is the last drug you should inject. It is best reserved for the novice athlete who is just starting out and wants to build his/her body. Further one must not anticipate engaging in sports for that time period. Every sporting organization has banned the use of the drug and it is always checked in the urine. The tests available can identify boldenone and its metabolites.
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. Not a rapid mass builder, instead Boldenone will be 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.
