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.
Applications
quipoise is used by athletes and bodybuilders to increase endurance, muscle mass and the production of red blood
cells in the body. It is best known for providing slow but steady gains during bulking cycles (usually called the EQ
gains). EQ can be used in dosages ranging from 200mg to 600mg per week for as long as 12 weeks.
In recent years, equipoise has become a favorite among powerlifters and is considered by coaches as an ideal
replacement for deca durabolin. This is primarily because the quality of muscle mass and strength gains that are
experienced while on equipoise happen without the nasty side effects of deca. Also, EQ has a positive effect on the
circulation of blood in the body; allowing for maximum blood flood to muscles during intense training sessions.
