Bold is a steroid compound that can give users slow but steady gains during a cycle. It is also relatively safe with very few reports of the side effects caused by testosterone conversion into estrogen. For bodybuilders, it should be used with some testosterone as Equipoise can cause sexual dysfunction. Bold long-lasting ester means it should be used for a minimum 12-week cycle. Bold is the popular brand name for the veterinary injectable steroid Boldenone Undecylenate. It 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 three or four weeks. In the veterinary field Bold is most commonly used on horses, exhibiting a pronounced effect on lean bodyweight, appetite and general disposition of the animal. As with all steroids, this compound shows a marked ability for increasing red blood cell production. In recent years this compound has become a favourite among athletes. Many consider it an ideal replacement to Deca. Bold has a release time of around 15 days. Dosages are around 200mg-600mg per week.
