All about Boldenone Undecylenate (Equipoise).

For two reasons, boldenone is very popular among athletes and bodybuilders. It’s a wonderful anabolic steroid well known long time and are used by all bodybuilders and athletes which are appreciate the uniqueness of this pharmaceutical steroid.

Boldenone was created exclusively for the needs of veterinary medicine and was originally intended to increase the mass of horses, cows to improve the appetite and general condition of domestic animals. The long-term successful veterinary practice of using equipoise in the field of animal finally attracted the attention of professional bodybuilders who appreciated the miraculous effect of this drug on their bodies.

In general, we know many cases when veterinary pharmaceutical steroids migrated from the field of animals to the sphere of people “treatment” (trenbolone, for example). There are also examples of reverse “classification” of steroids – for a very long time nandrolone has been used to “humanize” animals (that is, vice versa).

Over the past ten years, a lot of theoretical and practical information has accumulated on the use of boldenone and on the features of its effect on the athlete’s body. In my article, I will try to systematize and summarize everything that has been written about this anabolic in numerous publications.

Boldenone cycle

Here is what William Llewellyn writes about Boldenone Undecylenate in his (Anabolics 2006):

Equipoise is a strong anabolic steroid, with moderate androgenic properties. Undecylenate ester significantly lengthens the period that steroid is in the blood (undecylenate is longer than the decanoate by one carbon atom). The androgenic index of boldenone is 50; anabolic index – 100; estrogenic activity is low; progestogen activity is low.

As you know, everything is known by comparison – so in order to better understand the mechanism of boldenone, it is necessary to compare its effect with the other androgenic and anabolic steroids. Here’s what are written about the similarity of Equipoise and Methandienone:

Even at first look, even if not very closely, on the molecules of methandrostenolone and boldenone undecylenate, you can see that they are not just similar. If we discard the methyl group in the 17th position in the first case and the ether chain in the same position in the second, then these molecules will become absolutely identical. I admit, such an identity for a long time confused many experts who considered boldenone undecylenate to be an injection analogue of “Methandienone”. In fact, it is very far from the truth.

The methyl group at position 17 changes the dimensional structure of the methandrostenolone molecule and as much changes the properties of the steroid. In addition, it must be taken into consideration that Dianabol loses this methyl group with great difficulty – in two or even three passes through the liver. That’s despite the fact that boldenone should, in theory, aromatize more, the “rating” of its aromatization is much lower than the same “rating” of Dianabol – this is the first difference between the steroids . The second, not less important, is the almost complete inability of methandrostenolone to stabilize (activate) the androgen receptor. The causer here, again, is the same methyl group. Boldenone stabilizes the androgen receptor not just well – here it comes very close to nandrolone. The only, in fact, that indicates a close relationship between boldenone and methandrostenolone is its ability to stimulate appetite. By the way, this makes boldenone very attractive for a bulking cycle, although the use of its cheaper “brother” is much more preferable here.

Boldenone

Most authors note also similarities between boldenone and testosterone:

Boldenone is similar to testosterone, the difference between their molecules is only in the presence of an additional double bond between positions 1 and 2 (ring A). But this difference is the one which making this drug universal – thanks to the mentioned double bond, boldenone is practically not affected by the enzyme 5 -? – reductase. Let me remind you 5 -? – reductase promotes the conversion of testosterone to a much more powerful dihydrotestosterone (DHT). DHT not only stabilizes the androgen receptor better, it differs to a certain extent from testosterone in its own properties.

So, we can say that 5 -? – reductase changes the properties of the primary material. So, the properties of boldenone remain constant and unchanged, doesn’t matter who takes the steroid – this is what makes it universal.

Boldenone Undecylenate can be considered as a softer version of testosterone. Indeed, the way how do they act in the system, to a certain extent, seems that both stabilize the androgen receptor well, both have non-genomic activity, although this property is much better expressed in testosterone. Another difference – the ability to increase the synthesis of muscle fibers of IGF-1 under the influence of even high doses of boldenone wasn’t noticed.

Very interesting is a comparison of nandrolone and equipoise:

Strangely but Boldenone Undecylenate turned out to be closest in its properties to nandrolone. Despite the dissimilarity of the molecular structures of these two steroids, both equipose and nandrolone have approximately the same addiction to aromatize (while, naturally, the difference is that the conversion of nandrolone to estradiol occurs without the participation of the aromatase enzyme). Moreover, the androgen receptor stabilization time for these steroids is approximately the same. Many experts recommend nandrolone and equipoise to be used separately one as a replacement of other and not as a mix of both of them in a cycle. In my opinion, this is not entirely justified and that is why.

5 -? – reductase converts nandrolone into dihydronandrolone, a much weaker substance with regard to the androgen receptors activation. Considering that equipoise is not subject to transformation with the help of 5 -? – reductase, can be considered as a more powerful steroid than nandrolone. In addition, boldenone undecylenate has expressed, although not as strong and clearly as its “brother” methandrostenolone, non-genomic activity, which is not the case with nandrolone. That is another plus for equipoise.

On the other hand, nandrolone has quite expressed progestogenic activity, which already allows it to overtake boldenone in terms of weight gain, although not so significantly. To enhance the “mass-gaining effect” of boldenone undecylenate in veterinary practice it is combined with a substance such as methandriol dipropionate.

Application and combination of Equipoise

Equipoise undecylenate can be included both in bulking cycle and in drying cycle as well. There are a lot of options for using boldenone undecylenate, we will focus on the main and most, in our opinion, effective.

Usually newbies to pharma need to inject 300 mg – 600 mg of the steroid per week, for experienced athletes the working dosage starts from 600 mg to 1.5 g per week.

Equipoise cycle

Since boldenone almost does not aromatize and does not have progestogen activity, and also has a very long half-life, so for gaining good muscles it is ideal to combine equipoise with long esters and composite testosterone (enanthate, cypionate, omnadren, sustanon). Here, the property of equipoise to increase appetite is very good. To optimize such a cycle in addition to testosterone you can take methandienone (dosage of 30 mg – 50 mg per day), turinabol (dosage of 40 mg – 60 mg per day), anadrol (dosage of 50 mg – 150 mg per day – this is an option for advanced athletes with good pharma background).

Here is one of the options for mass gain: Equipoise 600mg per week; Enanthate 500mg per week; Methandienone 40 mg per day; cycle length – 8 weeks.

Quite often, boldenone undecylenate is used on bulking cycles as a replacement of nandrolone, because it does not inhibit the production of endogenous testosterone as much as nandrolone … and, unlike the latter, is not a progestin.

In some publications, another interesting property of boldenone is mentioned:

it stimulates the release of erythropoietin in the kidneys, which leads to an increase in the number of red blood cells. This property is important for representatives of those sports where athlete endurance is at the forefront. However, for bodybuilders this property is not so insignificant; one of the mechanisms of muscle growth is based on an increase of the number of capillaries in the muscle. Yes, and increasing venous, especially in before the competition is an important thing.

Now let’s talk about the main purpose of boldenone undecylenate – “drying and preparation” of bodybuilders. Although equipoise is not suitable for pre-competitive drying cycle of athletes, since when using it, it is not possible to avoid even a little water retention in the body, because the drug is still subject to slight aromatization. Therefore, equipoise is ideal to become ready for the beach season, when you want to shine with six packs and show good venous muscle body.

Drying cycle which is based on boldenone, may also include trenbolone, winstrol (injectable or tablet), testosterone propionate, turinabol, masteron, oxandrolone and, in some cases, primobolan.

In order to make it easier for the reader to imagine what such cycles are like, here are two options.

1. Boldenone 800mg per week + Sustanon 500mg per week, all this for 10 weeks. Also, the first 6-8 weeks you can take Turinabol 40mg per day. After ten-week “loading phase” with equipoise and testosterone, we switch to a four-week “output” on short propionate in a weekly dosage of 500 mg.

2. Boldenone Undecylenate 600mg per week + Testosterone enanthate 400-500g per week – this is the first part of the cycle for a period of 8-10 weeks; during this period, you can take Dianabol as well in the dosage of 40-50 mg per day. Then the standard “output” on the testosterone propionate.

Equipoise Side Effects

About such great anabolic, the following can be read in the specialized sport and medicine literature:

The double bond between 1 and 2 carbon atoms is responsible for many Equipoise properties. First of all, it inhibits the process of aromatization (conversion to estrogen) of the steroid. When compared with testosterone, the conversion level of boldenone is twice lower. Athletes almost never notice such side effects of boldenone which is related to estrogen (gynecomastia, edema, increased pressure), even if the dosage reaches 1 g per week. This means that during Equipoise cycle there is no need to take antiestrogens.

The same double bond provides the Equipoise resistance to the enzyme 5-alpha reductase. This enzyme converts a small amount of boldenone to dihydroboldenone, which is a powerful anabolic. Therefore, the drug practically does not cause such androgenic side effects as baldness, acne, prostate hypertrophy, etc., and less inhibits the production of own testosterone in the body.

Low androgenic activity allows female athletes to use equipoise. Virilization phenomena occur quite rarely, compared with other steroids. Boldenone is one of the few injectable drugs that can be used in female’s bodybuilding with the less risk of side effects.

Theses:

1. Athletes have been using this “veterinary wonder” for many years, due to which some experience has been gained of its use in bodybuilding and other sports disciplines.

2. It can be said that boldenone is an “ideal” anabolic, which has a wide range of possible uses in sports practice and does not have those side effects that other “heavy” anabolic steroids possess (for example deca).

3. Boldenone Undecylenate is almost doesn’t have aromatization, which allows it to be classified as a “soft” steroid (in the same “safe” category of AS you can find Primobolan, Oxandrolone, Masteron, Winstrol). You can use equipoise not on pre-competitive “drying” cycle, because Boldenone, although minimally, but retains water, here we talk about “bringing” muscle mass.

4. Boldenone has the ability to stabilize (activate) the androgen receptor, which makes it similar to nandrolones. It also has another interesting feature – the ability to stimulate appetite, which makes it very similar to testosterone and dianabol. These two characteristics make boldenone a good helper in the fight for muscle mass, i.e. perhaps his participation in the bulking cycles.

5. Boldenone is a steroid for “cautious” users who care about their health, and for beginners. If you already have a dozen cycles behind which included “heavy” ASS, then you will almost not feel the effect of using Equipoise, while beginning user can truly appreciate all the benefits of this “soft” steroid.

6. The working dosage for beginners is from 300 mg to 600 mg per week, for athletes with experience from 600 mg to 1000 mg. I recommend that experienced pharma users do not put less than 1g per week – it makes no sense.

7. Boldenone is almost non-toxic to the liver.

8. The drug almost does not cause such androgenic side effects as baldness, acne, prostatic hypertrophy, etc.

9. Boldenone stimulates the release of erythropoietin in the kidneys, which leads to an increase in the number of red blood cells. Such a property is important for those sports representatives where athlete endurance is at the forefront, i.e. not only bodybuilders, but also athletes can use equipoise.

10. Synonyms for boldenone – Equipoise, Ganabol, Boldesten, Boldabol.

There are several negative points when using this steroid:

1) Blood rheology worsens, hematocrit grows due to increased production of red blood cells under the action of boldenone. Perhaps on boldenone cycle, you will have to drink pentoxifylline, which prevents the aggregation of red blood cells.

2) In many users bodies Boldenone acts as an aromatase inhibitor, due to which the conversion of Testosterone to Estrogens decreases, therefore monitoring of estradiol levels on the cycle is prevented so that this hormone does not go to zero.

3) Equipoise has a very long half-life, so it is very long “output” from the body after cancellation. Accordingly, there might be a situation when you have to wait more than a month after the last injection to start PCT.
