For bodybuilders, it should be used with some testosterone as Equipoise can cause sexual dysfunction.

Equipoise is a steroid compound that can give users slow but steady gains during a cycle.It is also relatively safe with very few reports of the side effects caused by testosterone conversion into estrogen. For bodybuilders, it should be used with some testosterone as Equipoise can cause sexual dysfunction. Equipoise’s long-lasting ester means it should be used for a minimum 12-week cycle.

Equipoise® is the popular brand name for the veterinary injectable steroid boldenone undecylenate. 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 the veterinary feild Equipoise is most commonly used on horses, exhibiting a pronounced effect on lean bodyweight, appetite and general disposition of the animal. As with all steroids, this compound shows a marked ability for increasing red blood cell production. In recent years this compound has become a favorite among athletes. Many consider it an ideal replacement to Deca-Durabolin.

The side effects of 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. If we look at aromatization studies, they suggest that its rate of estrogen conversion should be about half that of testosterone’s. Water retention with this drug would therefore be slightly higher than that with Deca-Durabolin (with an estimated 20% conversion), but much less than we would find with a stronger compound as Testosterone. While there is still a chance of encountering an estrogen related side effect as such when using Equipoise, problems are usually not encountered at a moderate dosage level. Gynecomastia might become a problem, but usually only with very sensitive individuals or (again) with those using higher dosages. If estrogenic effects become a problem, the addition of Nolvadex should of course make the cycle more tolerable. An anti-aromatase such as Arimidex, Femara, or Amonasin would be a stronger option, however probably not necessary with such a mild drug.

Although typically dosage related, Equipoise can also produce distinct androgenic side effects. Oily skin, acne, increased aggression and hair loss are all possible with this compound. Women find this drug quite comfortable, virilization symptoms usually unheard of 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. Therefore the reductase inhibitor Proscar would not be of much use with Equipoise, as it would be blocking what is at best an insignificant path of metabolism for the steroid. Although this drug is relatively mild, it still has a depressive effect on endogenous testosterone levels, therefore a proper post cycle therapy HCG and Clomid/Nolvadex is needed at the conclusion of each cycle to avoid a “crash”. A waiting time of around 3 weeks is required before starting PCT, enabling enough of the drug to clear one’s system to make PCT effective.

In order to maintain stable blood levels, Equipoise should be injected at least once per week. It is most commonly used at a dosage of 400-600mg per week for men, 50-150 mg per week for women.

Equipoise is not a rapid mass builder, but will 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 at least 10 weeks in length. The muscle gained should not be the smooth bulk seen with androgens, but instead a very defined and solid look. 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 that difference, the drugs are basically the same. Of course they act quite differently in the body, which goes to show the 17-methylation effects more than just the oral efficancy 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 or an injectable testosterone. 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. When used in a cutting cycle, muscle hardness and density can be greatly improved when combining Equipoise with a non-aromatizable steroid such as trenbolone acetate, Halotestin, or Winstrol. 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.
