Boldenone Undecylenate is a highly anabolic and moderately androgenic steroid. Its primary use is in veterinary medicine most commonly with horses but regardless of this it has become a favourite of strength athletes and bodybuilders. There is very little aromatization related to the compound with a very limited amount of water retention experienced by most users.

Another attractive quality of the compound is the ensuing increase in appetite often reported by users when running this steroid and as a result it will often be included in "bulking" cycles for this purpose. Boldenone Undecylenate also increases Hemaglobin and Hematocrit (the number of red blood cells and the percentage of red blood cells), thus causing greater "pumps" while working out. Although this is true of nearly all anabolic steroids the effects are reportedly more pronounced with Boldenone Undecylenate. An improvement in vascularity should also be experienced due these increases (if body fat is at a low enough level).

Athletes other than bodybuilders or those concerned primarily with strength may also benefit. This is because the compound stimulates the release of Erythropoietin, commonly referred to as EPO within the kidneys. Erythropoeitin signals the body to increase the production of Erythrocytes (Red Blood Cells). Erythrocytes are the carrier of oxygen in the body and therefore if their concentration is increased in the body, a higher maximal oxygen capacity is produced and performance can be improved due to a delay in the on-set of fatigue, including the build-up of lactic acid. While the results would not be overly dramatic, a user should notice an improvement with all things being equal.



Due to the active life, injections are usually conducted twice per week to maintain stable blood levels although some users prefer injecting only once per week. Most users anecdotally report that the minimum dose for most males is between 300mg to 400mg to see any substantial effects from the drug. Women of course will see results at much lower doses, usually ranging from 50-150mg per week for less experienced users.

Like most compounds, most users prefer to stack Boldenone Undecylenate with Testosterone. This should negate any libido uses that a user may encounter, as well as providing a potent combination that should result in a dramatic increase in lean body mass. Due to the lack of liver toxicity associated with the compound, other compounds that can raise liver values (such as 17 alpha alkylated steroids) can be run with Boldenone Undecylenate without any further complications.

Many users believe that it can be used both in "bulking" cycles and "cutting" cycles, as the lack of water retention associated with its use and improvement in vascularity while on the compound can help to show improvement in definition while a user is reducing his or her body fat. At the same time, the compound has a profound effect on lean body mass and the results can be dramatic when run with a diet which is high in protein and calories, along with a proper training regime.

Not considered to be a rapid mass builder in comparison to other anabolic steroids, Boldenone Undecylenate will add quality lean muscle consistently throughout a cycle. Anecdotally, users have reported that cycles of at least ten to twelve weeks running Boldenone Undecylenate are needed to see the full effects of the compound.
