Boldaxyl 300 (Boldenone undecylenate)
Boldaxyl 300 (Boldenone undecylenate) is an injectable veterinary steroid that exhibits strong anabolic and moderately androgenic properties. The undecylenate ester extends the activity of the drug greatly (the undecylenate ester is only one carbon atom longer than decanoate), so that injections need to be repeated only once every 3 or 4 weeks. The well-balanced anabolic and androgenic properties of this drug are greatly appreciated by athletes, who generally consider it to be a stronger, slightly more androgenic, alternative to Nandroxyl 250. It is generally cheaper, and could replace Deca in most cycles without greatly changing the end result. Boldenone undecylenate is also commonly known as a drug capable of increasing red blood cell production, although there should be no confusion that this is an effect characteristic of nearly all anabolic/androgenic steroids.Boldenone is a modified form of testosterone. It differs by the introduction of a double bond between carbons 1 and 2, which reduces its relative estrogenicity and androgenicity. Boldaxyl 300 contains boldenone modified with the addition of carboxylic acid ester (undecylenoic acid) at the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) boldenone. Esterified steroids are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. Boldenone undecylenate is designed to provide a peak release of boldenone within a few days after injection, and sustain hormone release for approximately 21-28 days. It is interesting to note that structurally boldenone and methandrostenolone (Dianabol) are almost identical. In the case of boldenone (as applied here), the compound uses a 17-beta ester (undecylenate) to facilitate administration, while methandrostenolone accomplishes this with the use of a 17-alpha alkyl group. Aside from this, the molecules are the same. Of course they act quite differently in the body, which goes to show that the 17-methylation affects more than just the oral efficacy of an anabolic/androgenic steroid
Although it stays active for a much longer time, boldenone undecylenate is injected at least weekly for physique- or performance-enhancing purposes. It is most commonly used at a dosage of 200-400 mg (4-8ml,50 mg version) per week. The dosage schedule can be further divided to reduce the volume of each injection if necessary, perhaps administering the drug two to three times per week. One should also take caution to rotate injection sites regularly, so as to avoid irritation or infection. Not a rapid mass builder, boldenone undecylenate instead provides a slow but steady gain of strength and quality muscle mass. The positive effects of this drug become most apparent when it is used for longer cycles, usually lasting 8 weeks or more in duration. The muscle gained should also not be the smooth bulk associated with testosterone, but more defined and solid. Since water bloat is not contributing greatly to the diameter of the muscle, more of the visible size gained on a cycle of boldenone undecylenate should be retained after the drug has been discontinued. Boldenone undecylenate is a very versatile drug, and can be combined with a number of other agents depending on the desired result. For mass, it is commonly stacked with an injectable testosterone such as enanthate or cypionate. This should produce strong gains in muscle size and strength, without the same intensity of side effects of using testosterone (at a higher dose) alone. During a cutting phase, muscle hardness and density can be greatly improved when combining boldenone undecylenate with a non-aromatizable steroid such as trenbolone acetate or methenolone enanthate. Oral c-17 alpha alkylated agents such as fluoxymesterone or stanozolol may also be used, but will present some level of hepatotoxicity. For some, even the low buildup of estrogen associated with this compound is enough to relegate its use to bulking cycles only.
When used for physique- or performance-enhancing purposes, women take much lower doses of boldenone undecylenate than men, typically 50-75 mg per week. Women should take caution with the slow-acting characteristics of this preparation, which make blood levels difficult to control and slow to decline should virilization symptoms become present.
