Boldenone Undecylenate is an injectable anabolic steroid derived from testosterone, known for its veterinary and limited human use. Each injection typically delivers a sustained release of the hormone, promoting muscle growth and enhancing athletic performance. It's used illicitly by athletes to increase muscle mass and endurance, despite legal restrictions and potential health risks. Medical supervision is essential due to side effects such as cardiovascular issues, liver toxicity, and hormonal imbalances. Misuse can lead to serious health complications.
