Boldenone is a variant of testosterone molecule. Only on the basis of testosterone molecule, a double bond is added between the carbon atoms at position 1 and 2, which greatly reduces the characteristics of this hormone in androgen and estrogen. Then this structure is connected to a very long or large undecylenoic acid lipid, which controls the release time of Boldenone after entering the human body. The content of Boldenone peaked within 3-4 days of injection and continued to release for about 21 days.
Due to the structural change, the aromatization rate of Boldenone is only 50% of that of testosterone. Side effects of estrogen may occur, but the probability varies from person to person compared with testosterone. Although there is a lot of difference between anabolic capacity and testosterone, because Boldenone has less effect on estrogen, it can enable users to obtain cleaner muscle growth.
