Equipoise® is the popularly referenced brand name for the veterinary injectable steroid boldenone undecylenate. Specifically it is a derivative of testosterone, which exhibits strong anabolic and moderately androgenic properties. The undecylenate ester greatly extends the activity of the drug (the undecylenate ester is only one carbon atom longer than decanoate), so that clinically injections would need to be repeated every three or four weeks. In veterinary medicine Equipoise© is most commonly used on horses, exhibiting a pronounced effect on lean bodyweight, appetite and general disposition of the animal. This compound is also said to shows a marked ability for increasing red blood cell production, although there should be no confusion that this is an effect characteristic of newly all anabolic/androgenic steroids. The favorable properties of this drug are greatly appreciated by athletes, Equipoise® being a very popular injectable in recent years. It is considered by many to be a stronger, slightly more androgenic Deca-Durabolin®. It is generally cheaper, and could replace Deca in most cycles without greatly changing the end result.
The side effects associated with Equipoise® are generally mild. The structure of boldenone does allow it to convert into estrogen, but it does not have an extremely high affinity to do so. To try and quantify this we can look toward aromatization studies, which suggest that its rate of estrogen conversion should be roughly half that of testosterone's. The tendency to develop a noticeable amount of water retention with this drug would therefore be slightly higher than that with Deca-DurabolinO (with an estimated 20°/a conversion), but much less than what would be expected with a stronger agent such as Testosterone. While one does still have a chance of encountering an estrogen related side effect as such when using this substance, it is not a common problem when taken at a moderate dosage level. Gynecomastia might theoretically become a concern, but is usually only heaved of with very sensitive individuals or (again) those venturing high in dosage. Should estrogenic effects become troublesome, the addition of Nolvadex® and/or Proviron® should of course make the cycle more tolerable. An antiaromatase such as Cytadren® or Arimidex® would be stronger options, however probably not indicated with a mild drug as such.
Equipoise® can also produce distinct androgenic side effects. Incidences of oily skin, acne, increased aggression and hair loss are likewise all possible with this compound, although will typically be related to the use of higher doses. Women in fact find this drug quite comfortable, virilization symptoms usually unseen when taken at low doses. Boldenone does reduce to a more potent androgen (dihydroboldenone) via the 5alpha reductase enzyme (which produces DHT from testosterone), however its affinity for this interaction in the human body is low to nonexistent". We therefore cannot consider the reductase inhibitor Proscar® to be of much use with Equipoise, as it would be blocking what is at best an insignificant path of metabolism for the steroid. And although this drug is relatively mild, it may still have a depressive effect on endogenous testosterone levels. A combination of HCG and Clomid®/Nolvadex® may likewise be needed at the conclusion of each cycle to avoid a "crash", particularly when running long in duration.
Although it stays active for a much longer time, Equipoise® is injected at least once per week by athletes. It is most commonly used at a dosage of 200-400mg (4-8 ml, 50mg version) per week for men, 50-75 mg per week for women. Should a 25mg version be the only product available, the injection volume can become quite uncomfortable. The dosage schedule can be further divided, perhaps injections given every other day to reduce discomfort. One should also take caution to rotate injection sites regularly, so as to avoid irritation or infection. Should too large an oil volume be injected into one site, an abscess may form that requires surgical draining. To avoid such a problem, athletes will usually limit each injection to 3ml and reuse each site no more than once per week, preferably every other week. With Equipoise® this may require using not only the gluteus, but also the outer thighs for an injection site. Of course all problems associated with 25mg and 50mg dosed products are eliminated with the newer 100 mg and 200mg/ml versions of this steroid, which clearly give the user much more dosage freedom and injection comfort.
Not a rapid mass builder, instead Equipoise® will be looked at to provide a slow but steady gain of strength and quality muscle mass. The most positive effects of this drug are seen when it is used for longer cycles, usually lasting more than 8-10 weeks in duration. The muscle gained should not be the smooth bulk seen with androgens, but very defined and solid. Since water bloat is not contributing greatly to the diameter of the muscle, much of the size gained on a cycle of Equipoise® can be retained after the drug has been discontinued. It is interesting to note that structurally Equipoise® and the classic bulking drug Dianabol are almost identical. In the case of Equipoise® the compound uses a l7beta ester (undecylenate), while Dianabol is 17 alpha alkylated. Aside from this the molecules are the same. Of course they act quite differently in the body, which goes to show the 17-methylation effects more than just the oral efficacy of a steroid.
As discussed earlier, Equipoise® is a very versatile compound. We can create a number of drug combinations with it depending on the desired result. For mass, one may want to stack it with Anadrol 50®(oxymetholone) or an injectable testosterone such as Sustanon 250. The result should be an incredible gain of muscle size and strength, without the same intensity of side effects if using the androgen (at a higher dose) alone. During a cutting phase, muscle hardness and density can be greatly improved when combining Equipoise® with a non-aromatizable steroid such as trenbolone acetate, Proviron® (mesterolone; 1-methyl DHT), Halotestin® (fluoxymesterone), or Winstrol® (stanozolol). For some however, even the low buildup of estrogen associated with this compound is enough to relegate its use to bulking cycles only.
Equipoise® is not an ideal steroid for the drug tested athlete however. This drug has the tendency to produce detectable metabolites in the urine months after use, a worry most commonly associated with Deca-Durabolin®. This is of course due to the high oil solubility of long chain esterified injectable steroids, a property which enables the drug to remain deposited in fatty tissues for extended periods of time. While this will reliably slow the release of steroid into the blood stream, it also allows small residual amounts to remain present in the body far after the initial injection. The release of stubborn stores of hormone would no doubt also be enhanced around contest time, a period when the athlete drastically attempts to mobilize unwanted body fat. If enough were used in the off-season, the athlete may actually fail a drug screen for boldenone although many months may have past since the drug was last injected.
On the U.S. black market one of the most popular preparations as of late is the new Boldenon 200 from Ttokkyo. This is the highest dosed version of this steroid ever produced, and is likewise in very high demand right now. This is of course a tremendous improvement over the 25 and 50mg products circulating exclusively just a couple of years ago. Before the Ttokkyo product Denkall had introduced us to the 100mg version of their Ultragan product, which remains a popular and trusted item on the black market today. Ganabol from Middle and South America is also common, and is typical sold in 50 ml vials. However this steroid is also produced in 10, 100, and 250 ml versions. Available in both 25 and 50 mg/ml version, one would look for a large "50" on the label indicating the stronger product. Equi-gan and Maxigan from Mexico are also common as of late, and are acceptable. A 50m1 vial of either usually sells for $250-300 on the black market. Unfortunately the weaker 25mg/ml products are usually very close in price.
