Boldenone is a Testosterone derived Anabolic Androgenic Steroid. It can also be used as a cutting steroid. It is an excellent protectant of lean muscle mass. It is very versatile and can be used for both cutting and bulking cycles. During cutting cycles it's stacked with Trenbolone and Winstrol. While during bulking cycles it is stacked with Dianabol and Testosterone (Cypionate or Enanthate).
It will greatly protect you from loss of lean tissue. During most cutting plans of a competitive bodybuilding nature, while Boldenone is commonly used it is normally only used at the frontend of the cutting cycle. It will normally be discontinued during the second half of the plan due to possible Estrogenic activity. While total Estrogenic activity should be low, during this phase of supplementation any and all Estrogenic activity is normally avoided or at least minimised to the lowest point possible.
While Boldenone itself does aromatise, it occurs at a significantly less rate than that of Testosterone. Hence users should not have to worry about the onset of Gynecomastia or other Estrogen-related side effects, unless they are using very high doses and are highly sensitive to Estrogen.
Possessing decent anabolic properties it is however a very mild Androgen, thus those users who suffer bad side-effects of strong Androgens (such as Trenbolone for example) should not see such side effects with Boldenone use (unless very high doses are used).
