Chemical Characteristics of Boldenone
As previously mentioned, Boldenone is a synthetic derivative of Testosterone where it has been modified at carbon 1 and carbon 2 on the steroid structure, where double-bonds have been added between these two carbon atoms. This is what is known as the modification that is responsible for reducing Boldenone’s affinity for interaction with the aromatase enzyme (the enzyme responsible for the conversion of androgens into Estrogen). As a result, its Estrogenic activity is regarded to be lower than Testosterone. Boldenone is Boldenone with the Undecylenate ester attached to it. Specifically, ‘Undecylenate’ is Undecylenoic acid, but once bound to Boldenone it is properly referred to in chemistry as an ester bond (or ester linkage). Undecylenoic acid is chemically bonded to the 17-beta hydroxyl group on the Boldenone structure. The addition of this ester augments the hormone’s release rate and half-life to favor a longer window of release. The primary reason for the augmentation of its half-life and release rate is because once Boldenone Undecylenate enters the bloodstream, enzymes work to break the bond between the ester and the hormone, which takes a varying amount of time. The end result is that of the ester being removed from the hormone by these enzymes, and the result following this is pure Boldenone that is free to do its work in the body. This process of enzymes removing the ester from the hormone to which it is attached is what is responsible for the slower release rates. When the Undecylenate ester is attached to Boldenone, creating Boldenone Undecylenate, the half-life of Boldenone is now extended to 14 days, providing a slower release and activity of the hormone than the hormone otherwise would without this ester.
Additionally, as noted near the beginning of this section, Boldenone and Roxobol are structurally identical with the only difference between the two being that Boldenone contains a the Undecylenate ester attached to its 17-beta hydroxyl group, and Roxobol instead contains a methyl group attached to its 17-beta hydroxyl group. Roxobol contains the methyl group (also known as C17-alpha alkylation) in order to prevent it from being metabolized and broken down by the liver through oral ingestion. Aside from these modifications, the two hormones are exactly identical and would be considered the exact same compounds. However, both of these hormones act significantly different from one another in the body, which is a very strong indication that the addition of a methyl group (C17-alpha alkylation) to the 17th carbon does more than just affect the hormone’s resistance to breakdown in the liver – it actually changes the effects and properties of the anabolic steroid.
Properties of Boldenone
Boldenone being a derivative of Testosterone grants it many of the same properties. For one thing, it possesses the exact same anabolic strength rating (100), and it is also an aromatizable anabolic steroid, which means that Boldenone can and does convert into Estrogen in the body through interaction with the aromatase enzyme. However, its double-bond modifications between carbons 1 and 2 reduce its affinity for the aromatase enzyme, granting it a lower rate of aromatization and therefore a lower Estrogenic activity in the body.
What this means is that Boldenone will still convert into Estrogen, but at a far less significant amount than its parent hormone Testosterone. Although this is a very comforting fact and a pleasing property, the issue of Estrogenic side effects is still an issue and should not be ignored by any users. Therefore, individuals can expect not an elimination of potential water retention, but a vast difference in a reduction of it from Boldenone alone. Although at sensible and moderate doses, Boldenone should not exhibit bloating or any other estrogenic effects (depending on user sensitivity), the risk of these Estrogenic side effects will indeed increase as higher and higher doses of Boldenone are used. Increasing doses will mean increased rates of aromatization of the anabolic steroid into Estrogen.
Boldenone itself possesses a low androgenic strength rating (lower than its progenitor hormone Testosterone), which should be pleasing to individuals whom are sensitive to any number of androgenic side effects. Overall, individuals utilizing Boldenone can expect the same anabolic size, strength, and mass gains that would come from Testosterone with a lower incidence of Estrogenic activity and androgenic side effects. This means that gains from Boldenone itself should, for the most part, be fairly solid lean mass gains with minimal water retention (depending on dose) and would be a perfect addition to any bulking or lean mass cycle. It would even work as an appropriate replacement for Nandrolone in any stack.
