A single injection of Boldenone Undecylenate can slowly release and be used by the muscles for as long as six weeks after administration. The common believe in the steroid world is that Boldenone Undeclynate will take up to four weeks to build up in the body before the user sees noticeable effects. It is also believed that Boldenone Undecylenate will taper off slowly at the end of a steroid cycle, so using Boldenone Undecylenate at the end will help make Post Cycle Therapy more effective. Boldenone Undecylenate can be effectively incorporated in both "cutting" and "bulking" cycles due to the well balanced effects of this anabolic substance. Boldenone Undecylenate Dosage Doses of 400mg per week are normal when this steroid is used by itself. As part of a steroid cycle Boldenone Undecylenate can be used at a lower dose of 200mg per week, as long as the other steroid in the stack are dosed aggressively. For experienced steroid users the benefits are negligible at less than 200mg per week. It is being widely use for both purposes with great results. In order to maintain stable blood levels, Boldenone Undecylenate should be injected at least once per week. It is most commonly used at a dosage of 400-600mg per week for men, 50-150 mg per week for women. Boldenone Undecylenate is not a rapid mass builder, but will provide a slow but steady gain of strength and quality muscle mass. The most positive effects of this drug are seen when it is used for longer cycles, usually lasting at least 10 weeks in length. The muscle gained should not be the smooth bulk seen with androgens, but instead a very defined and solid look. Since water bloat is not contributing greatly to the diameter of the muscle, much of the size gained on a cycle of Boldenone Undecylenate can be retained after steroid has been discontinued. The side effects of Boldenone Undecylenate are generally mild. The structure of Boldenone Undecylenate does allow it to convert into estrogen, but it does not have an extremely high affinity to do so. If we look at aromatization studies, they suggest that its rate of estrogen conversion should be about half that of testosterone's. Water retention with this drug would therefore be slightly higher than that with Deca-Durabolin. Although typically dosage related, Boldenone Undecylenate can also produce distinct androgenic side effects. Oily skin, acne, increased aggression and hair loss are all possible when taking this substance. Women find this steroid quite comfortable, virilization symptoms usually unseen when taken at low doses.
