Everything you need to know about Equipoise (Boldenone undecylenate).

Known to many as the horse steroid (it is in the name), this drug is commonly sought after as a cheaper alternative to Primobolan. It is called the horse steroid due to its popularity amongst horse racers. Let us look at everything there is to know about the horse steroid.

First patented in 1949, Equipoise did not pick up popularity until the mid-60s. It was initially used for the treatment of muscle wasting disorders and osteoporosis, but it was discontinued at the end of the 70s. It was not until a few years later that it was introduced to the veterinary market. Although it is most used in horses, it is used with other animals due to its ability to promote lean tissue (muscle) growth.

How does Equipoise Work?
It is popular due to its strong anabolic effects and relatively low androgenicity. Boldenone also has two additional double bonds when compared to the molecular structure of testosterone, this results in lower oestrogen conversion and lower conversion to DHT. Instead Equipoise converts into dihydroboldenone (DHB) which is another potent androgen. There have been claims that Equipoise’s metabolites act as an aromatase inhibitor (this means it blocks the enzyme that converts testosterone to oestrogen). The research behind this is mixed and inconclusive. However, many anecdotal reports on bodybuilding forums have demonstrated that oestrogen levels are much easier to control on Equipoise. Another interesting effect of Equipoise is the ability to raise Red Blood Cell count. All anabolics have this ability, however, it is more pronounced with the use of Equipoise.

What are the side effects?
As alluded to in the previous paragraph, Equipoise does not strongly convert to oestrogen control and therefore there is not much of a need for anti-oestrogens.


As for cholesterol changes, Boldenone does increase LDL (bad cholesterol) and decrease HDL (good cholesterol), however, to a lesser extent than oral anabolic agents.

It is also not known to be liver toxic.

It has mild androgenic effects due to the lack of DHT conversion.

Equipoise does supress natural testosterone and therefore a post-cycle therapy will be needed to aid recovery of natural testosterone production.

Another side effect more specific to Equipoise is development of secondary polycythaemia. This is where blood production is increased and therefore the blood becomes thicker which can lead to higher incidences of clots.

How is Equipoise used?
The undecylenate ester allows for equipoise to have a longer half-life which is reported to be between 3 and 2 weeks. Weekly administration is still advised. Common doses for men include doses ranging from 200mg to 600mg a week. For women, doses tend to range from 50 to 70 mg a week. Cycles usually range from 8 to 12 weeks.

Equipoise is not known to be a quick muscle building anabolic steroid. It is known for its steady strength and muscle gains with minimal water retention. Therefore, it is best to use boldenone for longer durations to notice the effects.
