Boldebolin is an injectable steroid which contains the hormone Boldenone Undecylenate.

Boldebolin has become a very popular steroid with athletes and bodybuilders due to the fact that it has very low side effects and has anabolic properties which promote a steady gain in quality muscle mass over time.

Boldebolin can be effectively incorporated in both "cutting" and "bulking" cycles due to the well balanced effects of this anabolic substance. This steroid aromatizes very little, and therefore produces almost no estrogenic side effects such as water retention or "gyno" (the development of female tissue under the nipples in males resulting in unattractive and often painful lumps in this area), and therefore is a favorite among bodybuilders who are looking to make solid gains without the extra bloat, or are nearing contest.

Boldebolin also increases protein synthesis and red blood cell count meaning that nutrients are transported throughout the body much more effectively. Because of this, Boldebolin is able to make much more use of less food, enhancing its capabilities as an effective hormone to use when "cutting" and a bodybuilder is trying to reduce calories to get into contest shape. Also, the increased red blood cell count caused by this steroid also increases oxygen transportation throughout the body, thus giving athletes and bodybuilders much more endurance and the capability to endure cardio sessions for much longer periods of time, which obviously makes this drug even more popular among those looking to shed bodyfat.

Users of Boldebolin also report a dramatic increase in vascularity, which can also be attributed to the oxidizing benefits of Boldenone Undecylenate. Bodybuilders using Boldebolin in a cutting cycle often look to stack it with an oral steroid such as Stanozolol or Oxandrolone to further increase anabolic activity while keeping estrogenic side effects out of the picture.

Boldebolin also has properties which make it very favorable amongst bodybuilders looking to incorporate it into their bulking cycles. Users of this steroid often report an increase in appetite and the ability to eat more food easily when trying to gain weight in the offseason.

The mild nature and steady gains produced by Boldebolin also make it very effective for those looking to do longer cycles (12-20 weeks), where as most users note a continuous gain in muscle mass and strength over this time and credit the steroid with helping the muscles maintain a more defined, vascular tone throughout bulking .

Bodybuilders looking for size often stack Boldebolin  with other anabolic drugs such as a testosterone preparation and/or Deca-Durabolin .

Women bodybuilders are also fond of this steroid due to its mild nature and low androgenic properties. The most often side effect of the drug being an increase in libido, women find that the drug rarely causes any masculizing side effects when kept in a reasonable dosage range.

Male bodybuilders generally take Boldebolin in doses of 300-800 mg a week for 8-20wks, depending on goals, while women bodybuilders often find a dosage of 50-100 mg a week to be very effective for making quality gains while keeping side effects to a minimum. This steroid has a long half life (7-10) days and is most commonly injected twice per week to keep blood concentrations as steady as possible.
