Boldenone Undecylenate

Boldenone Undecylenate (Equipoise) History, uses, and side effects.

The anabolic steroid Boldenone Undecylenate is not a common steroid in the world of bodybuilding. It is better known as Equipoise. Equipoise is an anabolic androgenic steroid. Like most anabolic steroids, it is a derivative of testosterone.

Equipoise is classified as a veterinary grade steroid, the first release of Equipoise for medical use on humans was introduced by Squibb labs in the early 1970's.

History of Equipoise (Boldenone Undecylenate)

CIBA Pharmaceuticals released Equipoise in 1949 under the brand name Parenabol. Equipoise was used to treat certain ailments and did have some success. Its primary function was to treat muscle and bone wasting diseases. While it was used during the 1960's and 70's it was short lived. Probably because it had a slower impact on weight gain or muscle wasting when compared to other anabolic steroids.

Equipoise was once again released in the late 1970's by Squibb strictly for veterinary use to treat certain ailments in horses. Boldenone Undecylenate has been used to treat horses suffering from debilitating conditions caused by certain diseases. It helps promote weight gain and increases appetite.

Equipoise is Similar to Deca

This is not true, this notion that Equipoise is similar to Deca came from comments made by bodybuilder Dan Duchaine. This was only a rumor, the truth is that the compounds in DECA and Boldenone Undecylenate are completely different.

If there was one steroid that comes close to Equipoise it would be testosterone.

Why Do Bodybuilders Use Equipoise?

Equipoise is an altered form of testosterone, it carries a lower androgenic and estrogenic rating when compared to regular testosterone. Unlike testosterone which aromatizes at 100%, Equipoise aromatizes at half 50%. This may not be a bad thing.

While Equipoise is not as strong as testosterone many bodybuilders enjoy the effects the steroid offers because taking Equipoise with a good diet and supplementation plan can expect slow but solid lean muscle gains.

The half-life of Equipoise is about 15 days yet it can be detected in the blodstream for as long as 5 monhs.

Equipoise as a Bulking Steroid

Equipoise has been used by bodybuilders during offseason bulking cycles. Equipoise makes it easier to gain lean mass but the effects are much slower than with other steroids such as Anadrol and Dbol (So don't expect overnight results).

Hard gainers may find Equipoise useful because of its ability to stimulate appetite making it easier to consume the extra calories needed to pack on extra muscle mass.

Some of the benefits from Equipoise include the following:

  • Increase nitrogen retention
  • Increase IGF-1
  • Improve protein synthesis
  • Good for slow bulking cycles where quick results are not needed

Equipoise Can Help Increase Strength

Equipoise is a useful steroid for increasing strength, this can help boost endurance and athletic performance which would make it the perfect performance steroid for athletes. The unfortunate thing is that Equipoise can be detected in the bloodstream for up to five months. This would be a deterrent for most athletes, especially where anti-doping testing is common.

Side Effects of Equipoise (Boldenone Undecylenate)

In spite of Equipoise being considered one of the safer anabolic steroids it can have side effects, most are considered mild but as with taking any anabolic steroid, the possible side effects should not be taken lightly.

For men, most of the side effects are similar to those of other steroids which include hair loss or accelerated male pattern baldness. Equipoise can also increase LDL (bad cholesterol levels) so diet should be watched closely.

The biggest concern for most men is that taking Equipoise does suppress natural testosterone production. Because of this, men may want to stack Equipoise with another steroid such as Dbol, Tren or testosterone.

The effects of Equipoise, when taken by women, are not as harsh as with other steroids, doses under 50mg don't seem to cause any sort of virilization. However, this will vary. Women should avoid taking Equipoise for longer than 8 weeks in order to avoid any possible side effects.

One advantage Equipoise has over other steroids is that it is not hepatoxic so there should be little concern for liver damage when taking this steroid.

Equipoise Recommended Dosage

For men a recommended dose is 400 mg per week, it is best to split up the dose into two 200 mg injections one 200mg at the beginning of the week and another at the end. Equipoise has a half-life of 15 days which should be considered.

For women a much lower dose of 50-75 mg per week. Women should also understand that since there is a 15 day half life if they begin to experience the effects of virilization, they should immediately stop taking it.

Buying Equipoise

Probably the biggest issue with Equipoise is trying to find a legitimate product. There are so many counterfeit products sold online buyers should beware. Like with buying any steroid on the black market there is the risk of getting scammed or even worse getting a substance that is contaminated with bacteria. As with all anabolic steroids, they are illegal in many countries including the U.S so you should do your research carefully before buying Equipoise online.


Taking Equipoise can be a good experience for most bodybuilders because of its low estrogenic properties. It does take longer to work but if you are looking for slow and gradual muscle and strength gains Equipoise delivers. Most will notice a decrease in water retention when taking Equipoise, this is directly related to the effect of the steroid itself.

Most users would not experience any bloating or estrogenic side effects from taking Equipoise, women, on the other hand, should keep a close eye on symptoms of masculinization, especially if they exceed the recommended doses.

Equipoise is not one of the more popular steroids among bodybuilders which is understandable, especially when you consider there are other steroids that are more effective. Most men will prefer the effect of Primobolan over Equipoise, the results are quicker and it works great.

I should also note that many people who buy Primobolan online are usually getting Equipoise at 3 times the price.
